Which diagnostic test is commonly used to assess long-term glucose control in individuals with diabetes mellitus?
Fasting blood glucose test.
Oral glucose tolerance test (OGTT).
Hemoglobin A1c (HbA1c) test.
C-peptide test.
The Correct Answer is C
The HbA1c test measures the average blood glucose level over the past 2-3 months and provides information about long-term glucose control. It is commonly used to monitor diabetes management and assess the effectiveness of treatment.
Incorrect choices:
a. This choice is incorrect. The fasting blood glucose test measures blood glucose levels after an overnight fast and provides information about current glucose levels, not long-term control.
b. This choice is incorrect. The OGTT measures the body's ability to clear glucose from the blood and is used to diagnose diabetes and impaired glucose tolerance, but it is not typically used for assessing long-term glucose control.
d. This choice is incorrect. The C-peptide test is used to assess insulin production by the pancreas and is not typically used to assess long-term glucose control.
