A1c Test Results

5732

The AccuBase A_1c Testing procedure employs a multi-method HPLC (IE/BA) analysis to determine A_1c.  Samples are analyzed first by HPLC-IE to determine the presence of any abnormal hemoglobin's (such as "S or C", E, F, D, O, J and/ or unknown peaks) and to ensure the optimal total hemoglobin.

Samples are also analyzed by HPLC-BA (an interference-free) method to negate any carbmylated hemoglobin and/or chemical derivatives that might otherwise alter the actual A_1c value. 

This method of analysis is considered the most clinically appropriate procedure to use in the measurement of individual glycemic control by the Steering Committee Chairman of the National Glycohemoglobin Standardization Program (NGSP) and the International Federation of Clinical Chemistry (IFCC).

Normal Assay Range 4.2 % - 6.0%

A1c Derived Average Glucose (ADAG) Formula

(% A1c X 35.6 - 77.3) = ADAG mg/dl

After September 08, DTI Laboratories, Inc., will be reporting the latest formula developed by the NGSP/IFCC for the determination of average glucose associated with % A1c values.

Formula:

Estimated Average Glucose (eAG)

eAG mg/dl = 28.7 X HbA1c - 46.7
