Reconstituting Lyophilised Controls
What is Lyophilisation?
Lyophilisation or ‘freeze drying’ is the process by which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate processes:
- Freezing
- Primary Drying (Sublimation)
- Secondary Drying (Desorption)
There are many benefits to using a lyophilised control including; improved product shelf-life and enhanced stability of volatile analytes. For example, many lyophilised controls have a shelf life of up to four years from the date of manufacture resulting in a reduction of costly new lot validation studies. Furthermore, lyophilised controls can be aliquoted and refrozen to extend the working stability of the product.
Reconstituting Lyophilised QC Material
The process of reconstitution involves adding a specified volume of distilled water to lyophilised QC material. The water should completely dissolve the lyophilised contents, giving a liquid solution, which is ready for analysis.
Reconstitution is a straightforward process, but requires a high level of precision. Small errors can have serious implications to the reconstituted material:
- If too much water is pipetted during reconstitution, the material will be heavily diluted and results will be lower than expected
- If too little water is pipetted during reconstitution, the material will not be sufficiently diluted, and results will be higher than expected
- If the correct volume of water is pipetted, but a small amount of water gets stuck in the pipette tip due to poor pipetting technique, results will be higher than expected
If a lyophilised control has been reconstituted incorrectly the contents of the vial will be wasted. It is therefore vitally important that controls are reconstituted with care.
Materials and Methods Required
The list of requirements for an accurate and consistent reconstitution technique is not extensive, but each requirement is vital. Labs should have:
- Calibrated volumetric pipettes
- Sterile, appropriately sized pipette tips
- Distilled water, or other reconstitution fluid as specified
- Technician with good pipetting technique
- Lyophilised QC stored according to manufacturer’s specifications
How to Reconstitute Lyophilised QC Material
Each different lyophilised control may require slightly different preparation, always refer to the instructions for use before reconstituting control material. The below guide provides a general overview of the reconstitution process, using the Randox Human Assayed Chemistry Premium Plus control (HN1530) as an example
- Place the vial of lyophilised QC on a flat surface, carefully remove the lid and the rubber stopper making sure not to spill any material
- Using a calibrated pipette and sterilised pipette tip, add exactly 5ml of distilled water directly into the QC vial, ensuring no water is left in the pipette tip, or on the rim/side of the vial
- Place the rubber stopper and lid firmly back onto the QC vial, and leave to stand for 30 minutes
- After 30 minutes, gently invert the QC vial 10-15 times to ensure the contents is completely dissolved, making sure to avoid the formation of foam. It is important that you DO NOT SHAKE the vial. Alternatively place the vial on a roller for 30 minutes to ensure the contents is thoroughly mixed
- Once satisfied all material has been completely dissolved, proceed to use the QC product in accordance with the ‘Control’ section of the individual analyser application
- Once finished, refrigerate any unused material. It is good practice to label the vial with the date of reconstitution to prevent the use of material outside of the recommended stability period
- Prior to reusing lyophilised material, mix the contents thoroughly by gentle inversion, as highlighted in Step 4
Additional Considerations
It is important to remember that there may be slightly different reconstitution requirements for different QC material. For this reason, it is vital that the instructions provided on the QC Kit Inserts are closely followed.
Reconstituting lyophilised QC can be time-consuming. Therefore, Randox Acusera offer convenient 5ml distilled water serum diluent to assist laboratories with reconstitution of lyophilised controls. These user-friendly pour over vials streamline the reconstitution process and eliminate the risk of pipetting errors.

Product Focus: Randox HbA1c
![product-focus-hba1c-1024x232-px](https://www.randox.com/wp-content/uploads/2016/11/product-focus-HbA1c-1024x232-px.png)

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
Clinical Chemistry Calibration Serum
Third party calibrator covering 42 commonly used clinical chemistry tests. Method and instrument specific target values and ranges are provided for most chemistry analysers. Two clinically significant levels are available.
