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.
Week 1: HbA1C Quality Control
The Randox Acusera HbA1c control is designed for use in the quality control of both HbA1c and Total Haemoglobin assays. Assayed instrument and method specific target values and ranges are provided for all major systems and methods including HPLC. A reconstituted stability of 4 weeks keeps waste to a minimum and helps to reduce costs.
Main Features and Benefits:
Lyophilised for enhanced stability
100% human whole blood
Assayed target values provided for 2 parameters
Convenient bi-level pack containing two clinically significant levels of control
Stable to expiry date at 2°C – 8°C
Reconstituted stability of 4 weeks at 2°C – 8°C
Week 2: Liquid HbA1C Quality Control
The Randox Acusera Liquid HbA1C control is conveniently supplied in a liquid ready-to-use format and is ideally suited to both clinical laboratories and POCT helping to significantly reduce preparation time. With a stability of 30 days, waste and costs are also kept to a minimum.
Main Features and Benefits:
Liquid ready-to-use
Human based whole blood
Convenient bi-level pack covering clinically relevant decision levels
Stable to expiry date at 2°C – 8°C
Open vial stability of 30 days at 2°C – 8°C
Week 3: RIQAS HbA1C Programme
RIQAS is the largest international External Quality Assessment Scheme, with more than 40,000 participants in over 124 countries. World renowned for reducing the number of individual programmes required by even the most demanding laboratories, RIQAS covers 360 parameters across 32 flexible multi-parameter programmes. Effective consolidation in this way will not only deliver real cost savings but free up storage space and ultimately reduce the time spent preparing multiple samples at each survey.
The RIQAS Glycated Haemoglobin (HbA1c) EQA programme is designed to monitor the performance of HbA1c and Total Haemoglobin assays.
Main Features and Benefits:
Accredited to ISO/IEC 17043 designed to meet ISO 15189 requirements
Lyophilised for enhanced stability
100% whole blood ensuring a matrix similar to the patient sample
Monthly reporting allowing identification of any system errors sooner
Submit results and view reports online via RIQAS.Net
Register up to five instruments at no extra cost
ISO 22870- Are you meeting expectations?
Quality control has recently become crucial in the Point-of-Care (POC) field due to the introduction of ISO 22870 regulations and increased focus in patient safety. Quality control is critical in reducing turnaround time and saving money.
There is now an international standard specifically for POC testing, ISO 22870. This standard is intended to be used in conjunction with the standard for medical laboratories, ISO 15189. This means that aspects relating to Point-of-Care such as training, competence and documentation should be carefully planned, implemented and governed by a quality management system and there is a requirement for QC and EQA to be performed, where available.
POCT is typically carried out by non-laboratory staff, therefore when selecting the appropriate IQC material for POCT there are a number of key characteristics you must consider;
- Format of the material – QC material employed should be liquid stable, requiring no preparation, reducing the likelihood of human error and increasing convenience.
- Value assignment – all values must be accurately assigned. Look out for suppliers who use a large number of independent labs to determine the target value.
- Third party controls – manufactured independently from any specific instrument or method third party controls are designed to deliver unbiased performance assessment.
- Storage – for convenience controls should be liquid stable, as these can be easily stored in a fridge at 2oC – 8oC and won’t need to be shipped on dry ice.
- Stability – a control with a good open vial stability will mean that it can be used for longer with less waste produced, meaning it is more convenient for the medical professional to use.
- Transportation– the liquid stable controls can be conveniently stored at 2oC – 8oC reducing the need to ship on dry ice
- Minimal training– easy to use with little training required, therefore suitable for use by non-laboratory personnel
In addition to IQC, External Quality Assessment (EQA) must also be employed to ensure a comprehensive review of test system performance. It is best to select a programme that offers frequent reporting with a large database of users. This will enable rapid error identification and ultimately accurate and reliable patient testing.
Our Acusera liquid ready-to-use controls include:
- Blood Gas Control– A liquid stable control provided in easy to open ampoules for added convenience and ease-of-use. Assayed, method specific target values are provided for the most common blood gas instruments.
- Liquid Cardiac Control– This is a highly convenient liquid stable cardiac control offering excellent consistency. Assayed, instrument specific target values are provided for 8 cardiac markers, enabling flexibility and consolidation.
- Liquid Urinalysis Control– Liquid control that is compatible for use with both manual and automated methods of dipstick analysis. Available in convenient 12ml vials or 25ml dropper bottles with assayed ranges provided for 13 parameters covering the chemical examination of urine specimens.
- Liquid HbA1c Control– This is another highly convenient liquid ready-to-use control. With an open vial stability of 30 days, keeping waste and costs to a minimum.
Complementary EQA programmes are also available to meet the needs of ISO 22870.
