Adapted from Tables 2.2 and 2.5 in the complete 2023 Standards of Care.

*

For all three tests, risk is continuous, extending below the lower limit of the range and becoming disproportionately greater at the higher end of the range.

In the absence of unequivocal hyperglycemia, diagnosis requires two abnormal test results from the same sample or in two separate samples.

Only diagnostic in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis.
