An HbA1c measurement is used to assess glycemic control. Which of the following is the EXCEPTION to what it measures?
Show answer and explanation
Correct answer: C. Current (real-time) blood glucose level
HbA1c reflects AVERAGE blood glucose over the PREVIOUS 2-3 months (lifespan of RBCs). It does NOT measure current/real-time glucose (that's fasting glucose or postprandial glucose testing). It IS a percentage of glycosylated Hgb and DOES assess long-term diabetic control. 'Within 6 months' monitoring is incorrect — it reflects 2-3 months.
