HbA1c stands for what?

HbA1c stands for what?

• A. Hemoglobin A1c test
• B. Glycated hemoglobin assay
• C. Glycemic control analysis
• D. Anemia screening panel

Answer: (B)

HbA1c refers to the amount of glycated hemoglobin in the blood, and the best way to express that concept is glycated hemoglobin assay. When glucose circulates, it nonenzymatically attaches to hemoglobin in red blood cells, creating HbA1c. The degree of this glycation reflects the average blood glucose level over the life of the red blood cell, about 2 to 3 months, and the lab measurement (the assay) quantifies how much Hb is glycated. That’s why this option is the most accurate description: it specifies both the modified hemoglobin (glycated hemoglobin) and the method used to measure it (assay). The other choices describe related ideas or unrelated concepts (a general test name, a general glycemic control concept, or anemia screening) but do not name the molecule and measurement as precisely.
