Your patient asks you what the purpose of the Hgb A1C test is. The BEST answer is:
It tells us your average blood Sugar levels over the last 4 months
It tells us if your pancreas is producing the hormone insulin
It tells us your blood sugar levels without regard to your last food intake
It tells us how much sugar you have been eating over the last few months
The Correct Answer is A
A. The Hgb A1c test provides a snapshot of your average blood sugar levels over the past 2-3 months.
B. The Hgb A1c test does not measure insulin production. It measures the amount of glucose attached to hemoglobin in red blood cells.
C. While the Hgb A1c test is not affected by recent food intake, it doesn't provide a snapshot of your current blood sugar level. It reflects an average over several months.
D. The Hgb A1c test measures blood sugar levels, not directly sugar intake. While diet affects blood sugar, the test does not isolate sugar consumption.
