Pre-diabetes and Other Medical Tests

 

OGTT: See "oral glucose tolerance test."

Oral Glucose Tolerance Test (also called Glucose Tolerance Test and OGTT). A test used to help diagnose pre-diabetes, gestational diabetes, and type 2 diabetes.

The oral glucose tolerance test is given by a health care professional after an overnight fast. A blood sample is taken, then the patient drinks a high-glucose beverage. Blood samples are taken at intervals for 2 to 3 hours. Test results are compared with a standard and show how the body uses glucose over time.

OGTTs are also usually given to women who are pregnant to detect gestational diabetes.
