2 Hour Glucose Tolerance

The test is typically requested by healthcare professionals, such as endocrinologists, obstetricians, or general practitioners, when they suspect prediabetes or diabetes in a patient.

These tests are used when healthcare providers need to assess how a person's body processes glucose, commonly for diagnosing prediabetes, diabetes, or gestational diabetes in pregnant women.

In a 2-Hour Glucose Tolerance Test, a patient fasts for at least 8 hours, drinks a glucose solution, and then has their blood sugar levels measured four times over a 2-hour period to evaluate glucose metabolism.
