Product Spotlight: Liquid Urinalysis Control
Liquid Urinalysis Quality Control
The Randox Acusera Urinalysis Quality Control is designed primarily to ensure accurate test system performance however offer the laboratory additional benefits that will help them to meet regulatory requirements whilst also reducing costs and time.
Background
It is estimated that 1 in 2 people will be affected by a urological condition at some point in their lifetime. Conditions and diseases related to kidneys, bladder and prostate, among others, are commonplace and can be devastating for millions of men, women and children across the globe.
Urological conditions can be common, such as urinary tract infections, or they can be much more serious, for example, prostate or testicular cancer.
Urinalysis is used as a screening or diagnostic tool because it can detect kidney and metabolic disorders. Often, substances such as glucose or protein will appear in the urine before a patient is aware that they have a problem. In some conditions, urinalysis also provides an easy and economical test to track patient progress, for example, if you want to know if a condition is improving.

Product Spotlight: Maternal Screening
Maternal Screening Control
Background
A maternal serum screening test (MSS) is a blood test offered to pregnant women that helps determine the risk of Down’s syndrome and other chromosomal conditions, further testing can be offered if the patient is found to be high risk. It can be performed at 10 weeks (combined first trimester screening test), and 14-20 weeks (second trimester maternal serum screening test).
MSS is generally offered to all pregnant women, but the decision to have the test is a personal decision.
Quality Control is an important part of any diagnostic test but is of particular importance in screening methods, when a disorder must be detected without the presence of symptoms. In such screening methods, errors can present as false negative or false positive results both of which can have devastating consequences. In the case of maternal screening a false positive result could mean additional and often invasive procedures which can carry risk of harm to the unborn child. The accuracy and reliability of the laboratory test results are extremely important in minimising both false positive and false negative results.
Product Overview
The Randox Acusera Maternal Screening quality control is the only commercially available control which covers all six analytes used during first and second trimester screening of Down’s syndrome and Spina Bifida.

Product Focus: Randox HbA1c
This month’s product spotlight is our new Liquid HbA1c Control. Over the next few weeks, we will be taking a look at some of the QC solutions available from Randox for HbA1c.
Haemoglobin is an oxygen-transporting protein found inside Red Blood Cells (RBC). Glycated Haemoglobin is simply a haemoglobin with a glucose molecule attached. The higher the level of glucose in the blood the more glycated haemoglobin is formed. Red Blood Cells live for around 2-3 months, because of this the HbA1c test is used by clinicians to get an overall picture of average blood sugar levels for the last 2-3 months. For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications. It is suggested that an individual’s HbA1c target should be under 48mmol/mol or below 6.5%. By lowering your HbA1c, you help reduce the risk of long-term health problems.
HbA1c is used to monitor patients with diabetes providing an indication of how well the condition is controlled. A measurement of less than 6% of HbA1c in the sample indicates good glucose control and a lower risk of diabetic complications for the majority of diabetics.

Product Focus: Calibrators
Calibrators
The importance of accurate instrument calibration in the laboratory is often overlooked. At Randox Quality Control we believe that accurate calibration is the foundation for producing reliable patient results. In fact, we believe that this should be your first step in ensuring accurate instrument performance and something you should consider carefully.
Effective instrument calibration will provide you with a baseline for your analysers from which accurate results can be produced. This baseline is then used to adjust readings to match the computed value and ensure accurate patient results are reported.
Calibrator features you should consider;
As well as frequent recalibration, according to the instructions provided by the instrument / reagent manufacturer, Randox Quality Control recommends;
- Utilising a third party calibrator, such as those available from our Acusera range, which have independently assigned values and have not been optimized for use with any specific instrument or reagent system
- Ensuring the calibrator you employ has the same matrix as a patient sample
- Choosing a calibrator that is 100% commutable, ensuring it mimics the behaviour of a patient sample
- A multi-analyte calibrator with a long shelf life
