The OGTT (75g) for non-pregnant individuals assesses how the body processes glucose and helps diagnose diabetes or insulin resistance.
This test is used for individuals with risk factors such as obesity, family history of diabetes, or symptoms like increased thirst or frequent urination. It also helps monitor prediabetes or confirm a diabetes diagnosis.
After an overnight fast, the patient drinks a 75g glucose solution, followed by blood draws at timed intervals—typically at 1 and 2 hours.
