A standard oral glucose tolerance test should measure glucose and insulin at baseline and at 30, 60, 90, and potentially 120 minutes.

“so let me give you an example so when I use an oral glucose tolerance test with my patients I'm a bit of a stickler so if they take their 75 you know grams of glucose I measure their glucose and insulin at baseline administer the glue Cola 30 minutes later 60 minutes later 90 minutes later and if I'm feeling aggressive 120 minutes later weari measure the glucose the insulin and the FFA and maybe even the c-peptide but for simplifying it just the glucose and insulin”
