Control Reagent Monitors the Performance of HbA1c Assays

Good Quality control is essential to monitor accu­rately and efficiently the performance of glycated hemoglobin (HbA1c) tests. The HbA1c test is used primarily to identify the average plasma-glucose concentration over prolonged periods and is a more reliable indicator of long-term diabetic control than blood glucose. The new HbA1c control from Randox Laboratories (Crumlin, UK; www.randox.com) is made from 100% human whole blood and is designed to be consistent over repeated analysis. The HbA1c controls are lyophilized providing enhanced shelf life and stability. An extended shelf life reduces the frequency of lot crossovers and allows the user to sequester and use the same lot of control over a number of years significantly reducing reagent costs.
