International Diabetes Federation Position Statement on the 1-hour post-load plasma glucose for the diagnosis of intermediate hyperglycaemia and type 2 diabetes

Health services should consider developing a policy for screening for IH based on local human and technical resources.

1-h plasma glucose (PG) ≥ 155 mg/dL (8.6 mmol/L): considered IH; prescribe lifestyle intervention and refer to a diabetes prevention program.

1-h PG ≥ 209 mg/dL (11.6 mmol/L): considered T2D; repeat test to confirm diagnosis, then refer for further evaluation and treatment.

Use a 1-h oral glucose tolerance test (OGTT) subsequent to screening with a non-laboratory diabetes risk tool, and intervene early.

Redefine current diagnostic criteria for IH and T2D by adding the 1-h PG.
