Service Providers for Glucose Tolerance Test 3 hrs
A 3-hour Glucose Tolerance Test (GTT) evaluates how your body processes glucose over a 3-hour period, often to diagnose gestational diabetes or diabetes mellitus. Preparation involves fasting for 8-12 hours prior. A fasting blood sample is collected, and you then drink a glucose solution. Blood samples are taken at fasting, 1-hour, 2-hour, and 3-hour intervals to track glucose levels. Mild side effects, such as nausea, dizziness, or fatigue, may occur. Elevated glucose levels at two or more intervals typically confirm diabetes or impaired glucose tolerance. Factors like recent illness, stress, or medications may affect results, so inform your doctor of any conditions beforehand.
