About the test

This test checks for abnormally high glucose levels after eating, which may indicate gestational diabetes in pregnant patients. If initial results suggest gestational diabetes, a more detailed 3-hour oral glucose tolerance test is recommended for confirmation.

Who might consider it:

This test is particularly important for pregnant individuals who may show signs of gestational diabetes, a condition that can affect both mother and baby's health.
