Post-Prandial Blood Glucose (PPBG) Test

Does it matter what I eat before this test?

Eat your usual, typical meal rather than something unusually large, small, or sugary, so the result reflects your real day-to-day glucose response.

Why is this tested alongside fasting glucose?

Some people have normal fasting glucose but an abnormal rise after eating, so testing both gives a more complete picture of overall blood sugar control.

Can I drink coffee or tea during the 2-hour wait?

It's best to stick to plain water during the waiting period, since coffee, tea, and other beverages can affect blood sugar readings and the timing of the test.
