Show answer and explanation
Correct answer: D. Glycated hemoglobin (hemoglobin A1c)
- A. Serum glucose is a point-in-time blood glucose measurement — not the same as HbA1c.
- B. Fasting plasma glucose is a different test — measures blood glucose after an 8-hour fast.
- C. Insulin resistance index is measured differently (HOMA-IR, hyperinsulinemic clamp) — not HbA1c.
- D. Correct. HbA1c stands for glycated hemoglobin A1c — specifically hemoglobin that has been non-enzymatically bound to glucose. The 'A1c' refers to a specific fraction of adult hemoglobin (HbA). It is also called glycosylated hemoglobin.
