The doctor orders for a glycosylated hemoglobin test for a client with diabetes. The client asked you what the purpose of this test is. You explained that glycosylated hemoglobin is used:
  1. To check for anemia
  2. To determine the average blood glucose level for up to 4 prior months
  3. To compare hemoglobin to glucose levels
  4. To calculate the amount of glucose in hemoglobin for the past 6 months
Explanation
Answer - B - Glycosylated hemoglobin reflects the average blood glucose over the life of the red blood cells, usually 4 months. This test is not a ration of hemoglobin to glucose content, nor is it helpful in diagnosing anemia. The time frame of 6 months is too long.
