Diagnostic criteria for gestational diabetes based on plasma glucose concentrations after an oral glucose tolerance test.

	After 100 g Glucose [6]	After 100 g Glucose [7]	After 75 g Glucose [8,9]
Fasting	95/5.3	105/5.8	92/5.1
1 h	180/10.0	190/10.6	180/10.0
2 h	155/8.6	165/9.2	153/8.5
3 h	140/7.8	145/8.0	--

Glucose concentrations are expressed in mg/dL and mmol/L. Meeting two or more thresholds is usually required for diagnosis, although a single value is sometimes used (reviewed in Reference [5]).
