Criteria for Diagnosis of Diabetes*
Fasting plasma glucose ≥ 126 mg/dl -or-
2-hr plasma glucose ≥ 200 mg/dl post 75g oral glucose challenge -or-
Random plasma glucose ≥ 200 mg/dl with symptoms -or-
A1C ≥ 6.5%
*For criteria 1-3: Repeat test to confirm unless symptoms are present. It is preferable that the same test be repeated for confirmation. If two different tests are used (ie: FPG & A1C) and both indicate diabetes, consider the diagnosis confirmed, but if the two different tests are discordant, repeat the test above the diagnostic cut point.
Criteria for Pre-diabetes**
- Fasting plasma glucose 100 - 125 mg/dl -or-
- 2-hr post 75g oral glucose challenge 140 - 199 mg/dl -or-
- A1C 5.7% - 6.4%
**For all tests, risk of diabetes is continuous, extending below the lower limit of the range and becoming disproportionately greater at higher ends of the range.
