Why This Biomarker Matters

Screens for gestational diabetes and glucose intolerance. Abnormal results identify increased diabetes risk in pregnancy and warrant further testing for diagnosis and early intervention.

Overview

This test measures blood glucose 1 hour after consuming 50 grams of glucose, a simplified screening test for gestational diabetes and glucose intolerance. Unlike the standard glucose tolerance test, this does not require fasting and is more convenient for screening. Elevated glucose after the glucose challenge suggests impaired glucose handling and increased diabetes risk. This test is commonly performed during pregnancy (typically between 24-28 weeks) to screen for gestational diabetes, which affects maternal and fetal health. Abnormal results warrant a full diagnostic glucose tolerance test.
