Analysis of the accuracy and precision of the Axis-Shield Afinion hemoglobin A1c measurement device.

Point-of-care (POC) hemoglobin A1c measurement is now used by many physicians to make more timely decisions on therapy changes. A few studies have highlighted the drawbacks of some POC methods, e.g., poor precision and lot-to-lot variability. Evaluating performance in the clinical setting is difficult because there is minimal proficiency testing data on POC methods. In this issue of Journal of ...

Accuracy and precision of the Axis-Shield Afinion hemoglobin A1c measurement device.

BACKGROUND The Afinion HbA1c (Axis-Shield) is a newer point-of-care device for measurement of hemoglobin A1c (A1C) using a boronate affinity method unlike the more commonly used DCA immunoassay method (Siemens Medical Solutions Diagnostics). The Afinion's accuracy and precision, when compared with high-performance liquid chromatography (HPLC) and DCA methods, have not been established in pediat...

Measurement of Hemoglobin A1c

Evaluation of glycemia is used for the diagnosis and management of patients with diabetes. Glucose and hemoglobin A1c (HbA1c) provide complementary information and both are used to assess an individual’s glycemic status. The concentration of glucose in the blood indicates the subject’s glycemia at the time of blood sampling. However, blood glucose concentrations are modified by numerous factors...

Evaluation of the Afinion AS100 Point-of-Care Analyzer for Hemoglobin A1c

An evaluation of a new Afinion AS100 Analyzer was conducted to assess analytical performance. Precision was estimated by analyzing 2 control and 3 patient samples twice a day for 10 days. Accuracy was established by analysis of 6 samples from the National Glycated Hemoglobin Standardization Program for a 3-day period. Agreement was correlated to a laboratory method, the Variant II Turbo Hemoglo...
