Glucose Tolerance Test

Maryland rates for HCPCS 82951

This test checks how your body processes sugar over time by measuring blood glucose from a baseline sample and two additional blood draws taken after you drink a sugary solution, for three samples total. It's commonly used to help diagnose diabetes or gestational diabetes when a single blood sugar reading isn't enough for a clear answer. The multiple readings show how quickly your blood sugar rises and returns to normal.
