The long-term diabetic has had a glycosylated hemoglobin (HbA1c) test done to evaluate the effectiveness of his glucose control. The nurse evaluates the laboratory report of 5% to indicate that the effectiveness of the glucose control is:
a. excellent.
b. good.
c. fair.
d. poor.
A
The hemoglobin A1c (A1C) test (formerly called the glycosylated hemoglobin test) measures blood glucose over a period of many weeks. Glucose in the bloodstream attaches itself to the hemoglobin A (red blood cell) molecule and remains there for the life span of the red blood cell. Physicians use A1C test results to prescribe adjustments to a patient's treatment program for managing diabetes. Results of 4.9% to 6.7% are considered excellent results. Good results are between 7.6% and 8.5%. Fair results are between 9.4% and 10.0%. Poor control is considered 12.1% and 13.0%.
