Hemoglobin A1c (HbA1c)
AKA
hemoglobin A1c (glycated hemoglobin, glycosylated hemoglobin, HbA1c, or A1c) test
- Measure of glucose control for previous 2-3 months
- Goal for DM 6-7%
- Higher number=worse control
Blood test
hemoglobin A1c (glycated hemoglobin, glycosylated hemoglobin, HbA1c, or A1c) test
Factors that increase HbA1c
When the RBC turnover is slow, the red blood cells spend more time in the bloodstream which causes
Factors that decrease HbA1c
Individuals with a high/fast RBC turnover rate will have an artifically low HbA1c. Individuals who have high hemolysis, usually due to oxidation, replace their red blood cells faster than individuals with a normal hemolysis rate.
