HbA1c- An Indicator!!??


Hemoglobin Fractions

Glycohemoglobin - HbA1c

HbA1c as Diagnostic Tool
• HbA1c as an Indicator of glycemic control, recommended for diagnosis of Diabetes by ADA in 2010.

Test Results are not affected by - Time of the Day - Meal Intake - Exercise - Just Administered Diabetes Drugs - Emotional Stress

HbA1c level correlates well with risks of Diabetic complications.

[Reference: American Diabetes Association Clinical Practice Standards of Medical Care in Diabetes - 2010 Diabetes Care 2010;33, suppl.1: S4-5.]

Why Use HbA1c Vs OGGT/FPG!?
• • • • • The patient does not need to be fasting HbA1c is standardized and aligned to DCCT Better index of overall glycemic exposure and risk for long-term complications Substantially less biologic variability/ pre-analytic stability Relatively unaffected by acute (e.g., stress or illness related) perturbations in glucose levels

NIH Publication No 11-7816 Sept 2011.

HbA1c Standardization

Need for Standardization
• 1993: Diabetes Control & Complication trial (DCCT), correlated chronic complications of Diabetes to degree of glycemic control with HbA1c as an Index. April 1993: American Association of Clinical Chemistry (AACC) estd HbA1c Standardization Subcommitee. Goal: To relate Individual Lab HbA1c results to those of DCCT, where relationships of HbA1c values to MBG and to risks of complications has been established. 1996: National Glycohemoglobin Standardization Program (NGSP) implements rec...
