![]() HbA1c accuracy diagnosis of diabetes hemoglobin A1c point of care precision. The results indicate that the POC test evaluated here is accurate and precise using both fingerstick and venous whole blood. Imprecision ranged from 0.62% to 1.93% CV for fingerstick samples and 1.11% to 1.69% CV for venous samples. The mean bias was -0.021% HbA1c (-0.346% relative) using fingerstick samples and -0.005% HbA1c (-0.093% relative) using venous samples. The SD and CV by study site and overall were calculated.Īcross the assay range, POC test results from fingerstick and venous whole blood samples were highly correlated with results from the NGSP SRL ( r =. ![]() The precision of the POC test using venous blood was evaluated from samples run in four replicates on each of three test cartridge lots, twice per day for 10 consecutive days. The precision of the POC test using fingerstick samples was estimated from duplicate results by calculating the coefficient of variation (CV) and standard deviation (SD), and separated into its components using analysis of variance (ANOVA). The accuracy of the POC test using fingerstick and venous whole blood samples was estimated via correlation and bias with respect to values obtained by an NGSP secondary reference laboratory (SRL). Samples spanning the assay range were collected from prospectively enrolled subjects at three clinical sites. The accuracy and the precision of the POC Afinion™ HbA1c Dx test were investigated. Blood HbA1c levels are reflective of how well diabetes is controlled. The blood test for HbA1c level is routinely performed in people with type 1 and type 2 diabetes mellitus. ![]() Point-of-care (POC) hemoglobin A1c (HbA1c) testing has advantages over laboratory testing, but some questions have remained regarding the accuracy and precision of these methods. Hemoglobin A1c, often abbreviated HbA1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. ![]()
