The Afinion and DCA Vantage instruments increasingly underestimated the HbA1c compared to the CL as the HbA1c values increased. There are three National Glycohemoglobin Standardization Program (NGSP)-certified POC A1C devices available in the United States for use by health care facilities: the handheld A1CNow and two bench-top models called the Axis-Shield Afinion and the Siemens DCA Vantage ( 7 ). HbA1c levels obtained using Variant II (mean=7.9 95% CI=7.5-8.3%) and In2it (mean=7.9 95% C.I.=7.5-8.2%) instruments were found to have no statistical mean difference (p=0.21), while the values obtained using DCA Vantage (mean=7.2% C.I.=6.9-7.5%) and Afinion (mean=7.3% C.I.=7.0-7.6%) instruments were different (p<0.001) from those of the CL method. Normal fasting blood glucose - or blood sugar - is between 70 and 100 milligrams per deciliter or mg/dL for people who do not have diabetes. Since the use of point-of-care (POC) devices for monitoring HbA1c is increasing, it is important to determine how these devices compare in relation to instrumentation used in the central laboratory (CL).Įighty-eight randomly selected samples previously analyzed using the Bio-Rad Variant™ II Hemoglobin Testing System were run on three POC Analyzers (Siemens DCA Vantage™ Analyzer, Axis-Shield Afinion™ AS100 Analyzer, and Bio-Rad In2it™ Analyzer).Īll POC instruments showed good correlation to the CL method (R(2)>0.95 for all methods). ![]() Glycosylated hemoglobin evaluation is very important for assessing the control of diabetes. ![]()
