HEMOGLOBIN A1c- HbA1c
Pre-test preparation or requirements
• Sample can be drawn at any time. No fasting or special preparation required.
• Sample should taken in Citrated or EDTA vial.
Significance of test
In vitro quantitative determination of HbA1c in whole blood is utilized in long term monitoring of glycemia. The HbA1c level correlates with the mean glucose concentration prevailing in the course of the patient's recent history (approx - 6-8 weeks) and therefore provides much more reliable information for glycemia monitoring than do determinations of blood glucose or urinary glucose.
It is recommended that the determination of HbA1c be performed at intervals of 4-6 weeks during Diabetes Mellitus therapy.
Results of HbA1C should be assessed in conjunction with the patient's medical history, clinical examinations and other findings.
ADA recommended reference range-
Metabolically healthy <5.7 % HbA1c
High risk group 5.8 - 6.4 % HbA1c
Diabetic >6.5 % HbA1c
