Can I drink water during GTT test?

Water is generally allowed during the GTT to stay hydrated, but excessive consumption might dilute glucose levels. It's best to follow the specific instructions provided.

What is an abnormal GTT?

An abnormal GTT suggests impaired glucose metabolism. High levels may lead to a diagnosis of diabetes or prediabetes, necessitating lifestyle changes or medical intervention.

What is 75g GTT blood test pregnancy?

This test during pregnancy assesses glucose metabolism. Normal levels help ensure maternal and fetal well-being, while abnormal results may indicate gestational diabetes.

What is the 75g GTT test?

A 75g Glucose Tolerance Test (GTT) involves ingesting 75g of glucose, and blood samples are taken at intervals (usually 2 hours) to evaluate how efficiently the body handles glucose.

What is the principle of the glucose tolerance test?

The GTT measures how well the body metabolizes glucose. After fasting, glucose is ingested, and blood samples are taken at intervals to assess how effectively the body clears glucose.

What is a normal OGTT level in pregnancy?

A normal Oral Glucose Tolerance Test (OGTT) level during pregnancy is fasting <92 mg/dL, 1-hour <180 mg/dL, and 2-hour <153 mg/dL.

What is a normal GTT level?

Typically, a normal fasting glucose level for a Glucose Tolerance Test (GTT) is less than 100 mg/dL.
