When during pregnancy is a woman tested for gestational diabetes? How is the testing done?

All pregnant women are checked for gestational diabetes, according to The American Congress of Obstetricians and Gynecologists (ACOG).

The screening is usually done between 24 weeks and 28 weeks of pregnancy but is sometimes done earlier for women who have risk factors that increase the chances of having gestational diabetes, according to ACOG.

The screening involves a couple of steps, according to the National Institutes of Health (NIH).

First, you drink a sugary drink. An hour later, you have your blood drawn to check your blood sugar level. You do not need to fast for this test, and it can be done any time of day, according to the NIH.

If the level is higher than normal, you might have to have another, for which you will have to fast for at least eight hours before the test, according to the NIH.

Your blood sugar level will be checked before you start, then you will drink a sugary drink, according to the NIH. Your blood sugar will be checked again after one hour, two hours and maybe three hours to determine if your levels are again too high.
