What does A1C measure?

• A. Current blood sugar level
• B. Average blood sugar levels over the past 1-2 weeks
• C. Average blood sugar levels over the past 2-3 months
• D. Blood sugar levels during fasting

Answer: (C)

A1C measures the average blood sugar levels over the past 2-3 months. This test provides an important indication of long-term glucose control for individuals with diabetes or those at risk of developing the condition. The A1C test works by measuring the percentage of hemoglobin proteins in the blood that have glucose attached to them, reflecting how much sugar has been in the bloodstream over that time frame. This measurement is crucial for understanding how well an individual’s diabetes management plan is working and helps guide treatment decisions. In contrast, the other options refer to more immediate blood sugar readings or shorter time frames, which do not provide the same long-term perspective that A1C offers. By focusing on the average blood sugar concentration over months instead of days or weeks, healthcare providers can better assess the effectiveness of a patient’s overall diabetes management strategy.
