Postprandial is defined as 2-3 hours
after/post
a meal, when
glucose plateaus in the bloodstream. Thus, it serves as
a test of whether
a person may have diabetes, or of whether a person who has diabetes is successfully controlling their glucose levels. At 1 hour glucose is still on the rise not providing an accurate assessment. Another example is an OGTT for diabetes screening, the most important sample is the 2 hour sample.
