Full write-up
What is it
Postprandial Glucose (2h) is a metabolic biomarker that refers to a glucose measurement taken two hours after a meal. It provides a time-specific view of glucose following food intake and is reported in mg/dL.
How to test it
Postprandial Glucose (2h) is measured from a serum sample collected two hours after eating. The timing is central to the test: glucose changes in response to food, so collecting the sample at the intended two-hour point helps ensure the result represents the post-meal measurement being assessed.
Fasting is not required for this test. When arranging the collection, confirm when the two-hour interval should begin and follow the laboratory’s instructions so the sample is taken at the appropriate time. A result may be considered alongside Glucose Fasting, Hba1C, and Insulin Fasting, since these markers reflect different aspects of glucose regulation and can provide context for interpreting a post-meal measurement.
Because the result is reported in mg/dL and lower values are generally preferred within the stated interpretation framework, results should be read using the ranges shown with the test rather than in isolation. A clinician or laboratory professional can explain how meal timing, the reason for testing, and other relevant circumstances affect interpretation.
