Aliquoting for longer QC stability
Aliquoting for longer QC stability
Al-i-quot: An amount that is an exact divisor of the whole quantity of a substance (Collins Dictionary of Medicine, R. Young, 2005).
Why aliquot QC material?
Aliquoting QC material can extend the open vial stability of a lyophilised control, according to manufacturer recommendations. By splitting your QC material into a number of tubes and freezing these you can extend the working stability of the control, ultimately reducing wastage and the amount of money spent on unnecessary additional controls.
Example
A laboratory purchases a lyophilised QC with a volume of 3ml once reconstituted the control is stable for 7 days at 2-8oC. However, the laboratory only uses 1ml of this control per week, meaning that 2ml could potentially be wasted. The manufacturer states that the control can be frozen after reconstitution, extending the working stability from 7 days at 2-8oC to 30 days at -20 oC to -80oC. The following outlines the process for aliquoting reconstituted material and extending the control’s working stability.
Aliquoting reconstituted material
- Reconstitute the QC material according to the manufacturer’s instructions.
- Using a micropipette aliquot the required volume (generally a minimum of 0.5ml should be used) of reconstituted material into a tube.
- Repeat step 2 until all the reconstituted material has been aliquoted.
- Label each tube with the date the material was reconstituted to avoid the use of expired material.
- Store each aliquot at -20oC in a frost free freezer. Be sure to check the kit insert for frozen stability claims.
- Remove and thaw each aliquot as and when required making sure to use all material within the frozen stability period.
- Once thawed do not refreeze, dispose of any leftover QC material.
Conclusion
Aliquoting reconstituted material is an ideal way of extending the control’s open vial stability. This will ensure that your laboratory minimises the amount of QC material wasted and saves money by eliminating the need to purchase additional controls. Please note that not all lyophilised controls can be frozen like this. To ensure the controls you are selecting are suitable for aliquoting check the product’s kit insert or contact your supplier.

Inflammatory Biomarker Series: Antioxidants
So far in our inflammatory biomarker series, we have considered the clinical significance of measuring rheumatoid factor (RF) and C-reactive protein (CRP) to detect inflammation. Inflammation, either chronic or acute, is the body’s immune response to protect against harmful stimuli such as damaged cells, irritants or pathogens and can be present in a range of diseases and conditions.1 Measuring inflammatory biomarkers can assist clinicians in the identification of a particular disease or can provide a marker of treatment response. In this blog, we consider the role of antioxidants and identify relevant biomarkers which may be linked to inflammatory states.
What is an antioxidant?
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that produces free radicals, which are groups of very reactive molecules that can interrupt important cellular processes. Antioxidants are commonly referenced with regards to food, however antioxidants are also found in the body in the form of enzymes. Their purpose is to protect against the effects of oxidative stress to reduce damage from free radicals.
What is the link between antioxidants and inflammation?
Oxidative stress and the inflammation associated with it are the cause of most human disease. This would suggest that free radicals are implicated in many disease states for example rheumatoid arthritis, asthma, stroke, or cancer. Therefore antioxidants are important to protect against oxidative damage, thus reducing the risk of inflammation. There are a number of antioxidants which play a protective role the body, such as ferritin, superoxide dismutase, transferrin, uric acid and glutathione reductase.
Ferritin
Ferritin is responsible for storing iron and releasing it when required. Ordinarily, ferritin is found inside blood cells with only a small amount circulating in the blood. Ferritin is clinically significant at both high and low levels. Low levels of ferritin can highlight an iron deficiency which causes anaemia. Whereas elevated levels of ferritin can be a result of conditions such as rheumatoid arthritis, haemochromatosis, liver disease, metabolic syndrome, type 2 diabetes and renal failure.2 As ferritin is an acute phase reactant, levels will be elevated in any inflammatory state within the body.3
Transferrin
Transferrin is a protein that is responsible for binding and transporting iron in the blood. Transferrin acts as a preventative antioxidant as it binds with free iron, removing it from the bloodstream. This is a critical function, as free iron can stimulate the production of harmful free radicals. As transferrin is a negative acute phase protein, lower levels are associated with inflammatory conditions.7
Superoxide Dismutase
Superoxide is a by-product of oxygen metabolism and is one of the most damaging free radicals in the body as it can cause cell damage. Superoxide Dismutase (SOD) is an enzyme which catalyses the breakdown of superoxide into a less damaging oxygen or hydrogen peroxide. Therefore SOD preforms a vital defensive function to reduce oxidative stress.4 Extensive research exists which links oxidative stress to chronic inflammation, which can be a contributing factor to diabetes, arthritis, cardiovascular disease and cancer.5 Therefore if levels of superoxide dismutase are low, patients are at risk inflammation, for example, SOD levels are significantly less in rheumatoid arthritis patients.6
Glutathione Reductase
Glutathione reductase is found in red blood cells and plays a key role in maintaining cell function and preventing oxidative stress in human cells. Reduced levels of glutathione reductase can contribute to the prevalence of inflammatory states, suggesting that adequate levels of glutathione reductase are essential for optimal function of the immune system. 7, 8
Uric Acid
Uric acid is a waste product produced when the body breaks down chemical compounds called purines. It is a scavenging antioxidant that acts by inactivating free radicals. Elevated levels of uric acid is commonly associated with gout, a type of arthritis which is caused when crystals of sodium urate form inside joints causing rapid and painful inflammation.9 Other research has indicated that elevated levels of uric acid is associated with increased risk of cardiovascular disease.
Total Antioxidant Status (TAS)
TAS is a measurement of antioxidant function rather than quantity and considers the cumulative effect of all antioxidants present. The antioxidant defence system has many components, and a deficiency in any of these components can cause a reduction in the overall antioxidant status of an individual.10 Reduction in total antioxidant status has been implicated in several disease states including cancer, CVD, Arthritis and Alzheimer’s disease.
As demonstrated above, different types of antioxidants can help reduce different types of inflammation. Antioxidant tests can be requested from any doctor, who may also review dietary intake, investigate any symptoms and advise if testing is required. If antioxidant levels are found to be inadequate, improving them can be easily done through dietary changes, and can help reduce a body’s overall inflammation.

Inflammatory Biomarker Series: Rheumatoid Factor
What are inflammatory biomarkers?
The purpose of measuring an inflammatory biomarker is to detect inflammation, which can assist clinicians in the identification of a particular disease or provide a marker of treatment response. Inflammation, either chronic or acute, is the body’s immune response to protect against harmful stimuli such as damaged cells, irritants or pathogens.1 When inflammation occurs in the body, extra protein is released from the site of inflammation and circulates in the bloodstream.2 It is these proteins, or antibodies, which clinicians are testing for in the blood as they can indicate if inflammation is present.Like many inflammatory biomarkers, such as rheumatoid factor (RF), C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR), further tests will be required as testing for these tests alone does not provide a clearly defined diagnosis. However inflammatory biomarker tests can provide clinicians with a good indication of what may be wrong with a patient, which is why they are commonly tested for in a clinical setting.
What is Rheumatoid Factor?
Rheumatoid factor (RF) is an autoantibody which can target and damage healthy body tissue and in turn cause inflammatory symptoms.3 It is uncommon for this antibody to be present in healthy individuals, which is why it is a beneficial test to aid the diagnostic process. In particular, rheumatoid factor can be used as an inflammatory biomarker to assist in the diagnosis of rheumatoid arthritis (RA). However the rheumatoid factor antibody can also be present in healthy individuals or patients with systemic lupus erythematosus, liver cirrhosis, Sjögren’s Syndrome, Hepatitis and other conditions.4 If a test detects rheumatoid factor levels above 14 IU/ml, this is considered abnormally high.3
What is Rheumatoid Arthritis?
Rheumatoid arthritis is an autoimmune disease which attacks the lining tissue of joints, resulting in chronic inflammation. This disease commonly affects the hands, feet and wrists, with symptoms causing pain, fatigue and loss of bodily function and over time may even lead to multiple organ damage.5 Although diagnosis of rheumatoid arthritis requires a physical examination, testing for rheumatoid factor can be beneficial to assist in the diagnosis of this disease. Other blood tests that can be used to detect biomarkers associated with rheumatoid arthritis include C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), IgA, IgG, IgM and anti-cyclic citrullinated peptide (anti-CCP).
For health professionals
Randox Laboratories offer a leading portfolio of diagnostic reagents which includes a test for rheumatoid factor, with applications available for a range of biochemistry analysers. With a measuring range of 6.72 – 104 lU/ml, this assay can comfortably detect levels outside the normal range. Randox offer a complete diagnostic package for the screening of rheumatoid factor with a range of kit sizes, controls and calibrators available. Other inflammatory biomarker tests available from Randox include CRP, High Sensitivity CRP, Full Range CRP, IgA, IgG and IgM.

The Benefits of Peer Group Data to your Troubleshooting Process
Drive for more accurate results in your laboratory
We’ve all been there, you’re in the middle of a run of patient tests when you are alerted to an out of control event, such as your analyser is reporting QC results 25% low to target. What do you do? In reality, we all know that the problem is unlikely to correct itself, especially if it’s a calibration or analyser issue. Human error is a potential factor, however all possible causes must be eliminated to proceed with patient testing.
What’s the solution?
ISO 15189:2012 recommends that a laboratory should “have a procedure to prevent patient results in the event of a quality control failure”. Implementing an interlaboratory data management program which features peer group reporting can help you meet this requirement and monitor the results you are producing. Such programs can help detect errors in the analytical phase of patient testing, through the automatic application of pre-programmed QC rules, thus alerting staff to failed results.
Why must Peer Groups be a feature?
A peer group is defined as a “Community in which most or all members have roughly the same characteristics…” (Businessdictionary.com, accessed 2017). In this instance the characteristics could refer to the; instrument, test method or QC material in use. As such peer group programmes could help you detect errors in your laboratory by comparing your results to those who are employing a similar method, instrument and QC to what you are using, i.e. comparing apples for apples. Therefore it is essential that the peer group data you require is available in real-time, to ensure you are accessing the most up-to-date data when reviewing your patient test results.
Scenario
Take the example from the introduction. You’re in the middle of a run of patient tests when you are alerted to an out of control event, such as your analyser is reporting QC results 25% low to target. As part of your troubleshooting procedures, you are able to compare your results to the results of your peer group and note that this is an isolated incident. Consequently, you have eliminated a widespread problem with the QC, reagent or calibrator and narrowed down the root cause to one of the components in your test system. Thus saving you time in the troubleshooting process.
Benefits of Peer Group Comparison
There are a number of benefits to employing peer group comparison in your laboratory. Peer group data comparisons facilitate faster troubleshooting, helping you identify whether the problem you are seeing is unique to your laboratory, or if other laboratories are reporting the same issue. If other laboratories are reporting the same issue it is possible to conclude that there is a widespread problem with either the QC, reagent or calibrator. On the other hand, if it is not occurring within your peer group you will have to investigate further, reviewing your QC processes. As a result, you could resolve issues much quicker by eliminating either a supplier or laboratory issue. Furthermore, you can also eliminate the need for unnecessary repeat tests or instrument maintenance, saving both valuable time and money.
Other characteristics you should look out for
Whilst peer group comparison is a useful feature there are a number of other features you should consider when selecting the right interlaboratory data management program for you. These include;
- Automatic calculation of Measurement Uncertainty, Total Error and Sigma Metrics
- Multiple laboratory management on a single platform
- Accessing data anytime, anywhere via PC, laptop or tablet via a web-based platform
- All data charts you may require to assess whether any bias or imprecision issues are present
- Ability to combine data for multiple QC lots, analytes and instruments on a single Levey-Jennings or Histogram chart
- Automated data import via a direct connection to your LIMS

Randox supports calls from Oxford University for more accurate diagnosis of diabetes following report warning
Calls for more accurate diagnosis of people at risk of developing Type-2 diabetes have been supported by Randox, following a warning raised by an Oxford University study which looked into efforts to tackle the worsening epidemic of the condition.
The study, which was published in the British Medical Journal, examined results from the NHS’s programme which involves a screening test for pre-diabetes. The authors determined that the UK’s National Diabetes Prevention Programme is unlikely to have much impact because the blood tests used were inaccurate at detecting pre-diabetes, though these are currently the only ones available to doctors and patients. The study argues that if the screening is inaccurate then people will either be falsely reassured or receive incorrect diagnoses, which will not help the worldwide challenge to reduce people at risk of developing diabetes that continues to increase across the world.
It is estimated that Type-2 diabetes causes 22,000 early deaths every year in England alone. Across the UK over 3m people currently have the condition though experts say this will increase to 5m by 2025.
With current treatment taking up almost 9% of the annual NHS budget – roughly £8.8bn a year – the implications for future healthcare budgets are clear if this dangerous trend persists.
Global reagents Manger Susan Hammond said,
“Although we wholly back the NHS’s belief that positive lifestyle changes make crucial differences in people’s health and lives, we also believe that unless earlier and more accurate diagnostic screening is employed on a twin-track of treatment, this epidemic will continue to worsen. We welcome that this study highlights the fact that clinician’s s are currently limited in what they can use to tackle the threat posed by diabetes. There are emerging biomarkers they could be given access to, such as Adiponectin and determining a person’s risk of Metabolic Syndrome.”
Assessing Adiponectin levels allows doctors to calculate the amount of visceral fat stored around a patient’s organs. This deep fat, which is not visible to the naked eye, is linked to health problems including Type-2 diabetes. High levels of adiponectin equate to low levels of visceral fat which can be combated by improving your diet, exercise habits and even stress levels. Given that 70% of Type-2 diabetes can be prevented by lifestyle changes, there is strong correlation that by detecting low levels of Adiponectin and taking corrective and preventive action, it could results in a decrease in the numbers of people who develop the life altering condition.
In addition to a test for the Adiponectin biomarker, Randox Biosciences have created a Metabolic Syndrome Array that measures 12 markers associated with metabolic syndrome and cardiovascular disease. Metabolic Syndrome is a is a group of cardiovascular risk factors that affects over 20% of adults and results in a person being three times more likely to have a stroke or heart attack, and five times more likely to develop diabetes.
Mrs Hammond concluded,
“We would ultimately like to see all medical professionals who are at the forefront of patient care armed with the most accurate diagnostic tools available. Updating traditional practice may not be easy but we believe it is imperative to do so, if we are to effectively challenge this global epidemic.”
Randox remains focused on providing early diagnoses and preventing illnesses by providing innovative diagnostics tests that will continue to revolutionise the healthcare landscape.

Talented Teoranta: David McIntyre’s journey from the 2015 Open Morning to joining Team Randox
It’s not every day you get to have a cup of tea and a chat with someone who’s been involved in revolutionising the face of global health – that’s why we think our Open Mornings are so important.
Our next one is on Friday 23rd December at Randox Teoranta in Dungloe, Donegal – if you’re a scientist, engineer, software developer or software tester we’d love you to join us.
During our 2015 Open Morning, final year Engineering student David McIntyre came along to find out more, and was so inspired he left his CV. Now he’s part of our team. Read more to find out why.
Hi David, how did you start your career with Randox Teoranta?
I first came here on the Christmas Eve Open Morning 2015. I was home for the holidays, and as I was in my final year I was obviously thinking about where I would go after graduation. I already knew a few people who worked here and I’d heard it was doing some impressive things, but I wanted to see for myself what a €25m R&D facility looked like.
What was your first impression of the facilities here?
My first impression didn’t disappoint. It is a top class facility and is packed with the latest technology. You don’t see many companies as high end as this in Donegal- it’s really one of a kind. When I arrived I met Christina the Engineering Manager who gave me a tour of each of the departments. I was really pleased that I got to view the Randox Biochip as I’d heard a lot about it in the news, and I also get to walk about the manufacturing and engineering departments. I got to talk to some of the engineers and ask them questions, and see some of their design work which I was extremely impressed with. It gave me a good feel for the facility, because I could visualise myself here –where I’d be, and who I’d be working with. Everyone was very friendly which put me at ease straight away so I decided to submit my CV at the end of the tour.
How did you find the recruitment process?
As part of the recruitment process I was invited back for six weeks to undergo an assessment period which was a brilliant experience. It actually happened before University started back so it suited me perfectly.
At the end of the six weeks I was offered a full time positon which I was thrilled about. I was delighted that I was able to get a job in my own county and not have to commute long distances to work each day. Currently I live in to Kincasslagh, Belcruit, Co Donegal which is only 15 minutes from Dungloe.
What was the most challenging thing you faced during your first few months?
The most challenging thing that I faced in the beginning was getting used to how everything works. This was my first job related to my degree so I didn’t really know what to expect. It took a while to get used to procedures and dealing with documentation – with a global company there is a lot you have to get right!
I’m well settled in now and really enjoying my role here in Randox, especially working with our 3D printer. To be given the opportunity to work with a 3D printer is great, that’s really been the highlight of my year so far as it’s such a unique piece of equipment. I have had the opportunity to create gears and even bearings which has been really interesting. It’s such an impressive machine. We can design a part and print it the very same day. If you were going to do this via conventional methods you would need to create the drawings and send the drawings to a fabricator and then you would be waiting a week or so to get it back.
What advice do you have for anyone who is interested in engineering?
My advice to anyone who is interested in engineering or science is to definitely come along to the Open Morning 2016 and see what Randox Teoranta has to offer. It’s a fantastic facility in Donegal, in a beautiful location and you will get a good insight as to what goes on in a design and manufacturing facility.
This is something that you don’t really get the opportunity to do in college and it’s a chance to get some behind the scenes knowledge of what it’s really like to work as an engineer. Everyone who works here is very friendly so you can ask as many questions as you like. It worked out great for me – it could do for you too!

Senior R&D Scientist at Randox Teoranta in Dungloe, Dr Sarah Gildea, on her PhD in Equine Influenza Virus and what she loves the most about being home
Since the opening of Randox Teoranta back in 2010, our team of scientists, engineers and software developers has grown significantly.
Career opportunities at our state-of-the-art research, development and manufacturing centre is utilising the talented skill set of Donegal people and newcomers alike, while actively attracing the Donegal Diaspora back to the area.
Donegal graduates who are working away from home have the opportunity to return, or for those from further afield, they have the opportunity to experience the distinct Donegal lifestyle for the first time.
Senior R&D Scientist at Randox Teoranta in Dungloe, Dr Sarah Gildea, returned to her native Donegal to work in Randox Teoranta, after having worked in the Irish Equine Centre in Kildare. She chatted to us about her PhD in Equine Influenza Virus and what she loves the most about being home.
Hi Sarah, can you tell us a little bit about your background and where you started your career?
I’m originally from Ardara which is in the south west of Donegal and about half an hour away from Dungloe where Randox Teoranta is based. Once I graduated from the University of Limerick with a Bsc in Equine Science, I got a job in the Virology Unit of The Irish Equine Centre, which is in Kildare. I stayed there for 13 years and during that time I got the opportunity to complete my PhD in Equine Influenza Virus.
Why did you choose Randox Teoranta?
After travelling to Kildare each week I finally got the opportunity to return home to work last June when I was lucky enough to join the Randox Teoranta team here in Dungloe. Travelling to Kildare was beginning to take its toll on me – I wasn’t home until late Friday evening and then I was away again on Sunday so it was always a short trip home. Don’t get me wrong now, it’s great to travel and see different parts of the world that you wouldn’t get the opportunity to see otherwise, but being a bit of a home bird I had wanted to come home for a while. I never thought that I would get the opportunity to work at home in the field of science, especially veterinary science. So as you can imagine I was delighted when I heard that Randox was opening a new R&D site in Dungloe and was expanding their expertise to include a veterinary division. I thought it was such a rare opportunity to be given the chance to work in my area of expertise so close to where I grew up.
What’s the difference in terms of the facilities between Randox Teoranta and the Irish Equine Centre?
Coming from the Irish Equine Centre where I was involved in diagnosing diseases for race horse trainers and veteran surgeons from all around Ireland to Randox Teoranta where I am developing tests to supply the likes of Irish Equine Centre and like-minded companies had its advantages. I already had a broad knowledge of vet diagnostics and diseases but now instead of diagnosing diseases I am creating the innovative diagnostic tests that the Irish Equine Centre would use. It meant that I already had a good knowledge on the flaws of some of the current tests and my experience gave me a good insight for what’s important when developing new innovative diagnostic tests.
How important is it that companies like Randox invest in places like Dungloe?
By investing in science and engineering at Randox Teoranta I have not only been able to bring back my knowledge and experience to my home county, but also teach and educate those in the community who are interested in pursuing a career in science but don’t necessarily want to travel far from home. Randox Teoranta not only allows me to give back to the community but also make huge savings on travel expenses as I no longer have to commute long distances to work each day. But really the most important thing for me is being close to all my family and friends.

Inflammatory Biomarker Series: CRP
An inflammatory biomarker detects inflammation in the body. Inflammation is not just the immediate, short-term response of the body to an injury or infection. Inflammation within the body can be a long-term, chronic condition resulting in a number of health implications. In diagnostics, measurement of an inflammatory biomarker can not only detect acute inflammation but provide a marker of treatment response.
C-reactive protein (CRP) is an acute phase protein produced by the liver in response to inflammation, infection and tissue injury. CRP is a particularly beneficial inflammatory biomarker as it is detected much faster than other markers in the blood. Levels of CRP increase when inflammation occurs and therefore it can be a significant biomarker in a range of diseases, including the following.
Cardiovascular Disease
An increasing amount of research exists to suggest CRP is not only a useful, non-specific inflammatory biomarker, but it may have a direct influence on coronary heart disease and cardiac events1. Inflammation can occur when LDL cholesterol builds up in the artery walls causing atherosclerosis. Modifiable risk factors of atherosclerosis include smoking, diabetes, poor diet, high blood pressure and physical inactivity, all factors which subsequently increase the risk of heart attacks, ischemic stroke, peripheral artery disease and even vascular dementia2,3.
Studies have also shown that persistent low levels of CRP can contribute to a person developing CVD. Therefore using high sensitivity CRP as an inflammatory biomarker can detect low levels, helping to predict the likelihood of a patient developing CVD in the future.
Diabetes
Research suggests that inflammation in the body can influence the development of type 2 diabetes. With the ability to be managed through diet and exercise, type 2 diabetes is commonly associated with obesity. Research has shown that excess body fat can cause continuous chronic low-grade inflammation as a result of inflammatory cytokines and increased plasma levels of CRP. As a result, this chronic inflammation has the ability to cause insulin resistance leading to the development of type 2 diabetes4.
Rheumatoid Arthritis
A three year study which analysed the bone and joint health of 10,000 patient samples in India has found that inflammatory biomarkers, in particular CRP and ESR (Erythrocyte Sedimentation Rate) were raised in most of the samples compared to any other markers5. Although CRP is a non-specific inflammatory biomarker, it can be used alongside other tests, such as Rheumatoid Factor, to diagnose inflammatory joint diseases such as Rheumatoid Arthritis. Not only will CRP levels be higher due to chronic inflammation, but CRP levels can be monitored to assess levels of inflammation over time, allowing clinicians offer effective treatment.
Chronic Obstructive Pulmonary Disease (COPD)
COPD is a condition associated with inflammation of the lungs and airways. Studies have shown that measuring CRP levels is beneficial to detect exacerbations, when symptoms of COPD get suddenly worse and can last for several days. This is because CRP levels spike when exacerbations happen, causing lung function to deteriorate6.
Neonatal Bacterial Infections
CRP is one of the preferred and frequently used tests in neonatal units when diagnosing suspected bacterial infections, such as neonatal sepsis, in newborns who show signs on infection. Due to delayed synthesis during the inflammatory response, the sensitivity of CRP is lowest during early stages of infection. It is therefore critical that extremely low levels of CRP can be detected during diagnosis to distinguish whether symptoms are related to an infectious or non-infectious condition. This early detection then allows for rapid and appropriate neonatal treatment7.
Inflammatory Bowel Disease
Research suggests that using CRP as an inflammatory biomarker can help distinguish between Inflammatory Bowel Disorder (IBD) and Irritable Bowel Syndrome (IBS)8. Although IBD and IBS have some similarities in symptoms, IBD causes chronic inflammation, whereas IBS is a non-inflammatory condition. Therefore using CRP as a biomarker can allow clinicians to deliver a confident and accurate diagnosis.

Celebrate Christmas with Randox Quality Control
T’was the week before Christmas and all through the lab not a thing could be heard not even a sound. The analyser lay silent asleep in the corner, the lab staff at home dreaming of a few days’ rest, only a few more days to go before the big day!
The big man in red, what will he bring those who already have everything? Peace, happiness and health for their loved ones throughout the festive break, that would be the wish for everyone to make. And what better way to ensure they stay healthy, well it all begins in the laboratory…
An important consideration to remember when choosing your lab Quality Control (QC) is that approximately 70% of clinical decisions are based on laboratory test results. It is therefore essential that the results gained from laboratory testing are accurate and reliable in order to provide the appropriate treatment and avoid or prevent potential misdiagnosis.
Patient results are of the utmost importance for a laboratory and therefore running the best Quality Control material should be at the top of their agenda. QC material should have a number of features that allow a lab to judge the overall quality of their output. These features include the controls ability to be commutable (which means how well it reacts as a replicate of a patient sample), is it a true third party control that has been manufactured to provide an independent and unbiased assessment of performance, does your control come with clinically relevant levels and does it have a long shelf life as well as a good open vial or reconstituted stability? These are the questions lab staff will be asking themselves when deciding on what QC is the right QC.
So stay off Santa’s naughty list by providing accurate and reliable patient test results, do this by employing Randox QC in your laboratory. Our controls have been designed to deliver significant cost savings without sacrificing on quality. With consolidated controls (combining up to 100 analytes in a single vial) your lab can reduce QC costs and preparation time, the inclusion of analytes present at clinical decision levels will eradicate the need for additional controls and because of our long shelf life (2 years for liquid controls, 4 years for lyophilised) and excellent stability claims your laboratory can be sure that expensive lot changes will be a thing of the past! Our controls can be described as true third party and this, combined with the commutable nature of the controls, leads to us being able to claim that we have the best Quality Control material around.
So this Christmas when deciding what QC to choose – make sure you look no further than Randox Quality Control. Our QC family is known as Acusera and our product offering includes QC and calibrator material, Interlaboratory Data Management Program (Acusera 24.7), the world’s largest international EQA/PT scheme better known as RIQAS and the newest addition to the family, Linearity or Calibration Verification material.
We have packages for every lab regardless of size and budget and we guarantee you will become ho-ho-hooked on Randox QC.
Wishing you all season’s greetings and a prosperous New Year from everyone at Randox QC.
