Clinical Accuracy
The A1CNow+ test is annually certified(7) by the National Glycohemoglobin Standardization Program (NGSP) and therefore traceable to the DCCT. Further, each lot is factory calibrated using a set of blood samples that have been quantitated by an NGSP certified laboratory using an NGSP certified method. Since in-field calibration is neither needed nor possible, the user cannot alter the accuracy of the test. Allowing for the normal variation seen with all laboratory methods, a 7 percent A1C using A1CNow+ will thus be, on average, the same as a 7 percent A1C on other instruments that are also calibrated to NGSP standards.
