In Step 2 of the 2-step GDM test, how many of the four time-point thresholds must be exceeded to diagnose GDM?

Explanation:
In Step 2, you use a 100 g oral glucose tolerance test with four measurement points: fasting, 1 hour, 2 hours, and 3 hours after the glucose load. GDM is diagnosed if two or more of these four values meet or exceed the predefined cutoffs. This rule ensures that the abnormality is consistent across multiple time points, not just a single borderline value, which helps distinguish true gestational diabetes from random variation. If only one value is high, it does not establish GDM, and further evaluation would be needed.
