Typically, a normal fasting glucose level for a Glucose Tolerance Test (GTT) is less than 100 mg/dL.
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 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.
Why 75g of glucose is used in OGTT?
The 75g glucose load is used to challenge the body's ability to handle a larger amount of glucose, simulating the stress of a meal, providing a more comprehensive assessment.
