Diabetes / Glucose
Also known as: OGTT, Glucose Tolerance Test, GTT
No common urgent flag from this test alone.
This test checks how well your body takes sugar from your blood. It looks at how sugar moves into your muscles and fat. You will drink a sweet liquid first. Then, the test shows how your body deals with that sugar over several hours.
Doctors often order this test to look for or diagnose prediabetes and diabetes. They use it when other blood sugar tests are high, but not high enough to say for sure that you have diabetes.
Normal value ranges vary by lab, and interpretation can depend on whether you are pregnant or have other health conditions.
