Glycosylated hemoglobin (HbA1C) test measures the average blood glucose control of an individual over the previous three months. Which of the following values is considered a diagnosis of pre-diabetes?
A. 6.5-7%
B. 5.7-6.4%
C. 5-5.6%
D. >5.6%
Correct Answer: B. 5.7-6.4%
Glycosylated hemoglobin levels between 5.7%-6.4% are considered as pre-diabetes. The hemoglobin A1c (glycated hemoglobin, glycosylated hemoglobin, HbA1c, or A1c) test is used to evaluate a person’s level of glucose control. The test shows an average of the blood sugar level over the past 90 days and represents a percentage. Anyone with an HbA1c value of 5.7 % to 6.4 % is considered to be prediabetic
Option A: Glycosylated hemoglobin levels over 6.5 % are considered diagnostic of diabetes. Diabetes can be diagnosed with an HbA1c of 6.5% or higher. The American Diabetes Association (ADA) recommends that the HbA1c is checked twice a year in patients that are stable and well-controlled, versus every 3 months in patients with changes in their medications, or not well controlled.
Options C and D: Glycosylated hemoglobin levels less than 5.6 % are normal. For an HbA1c test to classify as normal, or in the non-diabetic range, the value must be below 5.7 %. Tests should be sent to a laboratory certified by the NGSP to ensure results are standardized.
