Can the HbA1c test detect gestational diabetes?

While the HbA1c test can provide information about long-term blood sugar control, it’s not typically used to diagnose gestational diabetes. Gestational diabetes is usually diagnosed through an oral glucose tolerance test (OGTT) during the second trimester of pregnancy. However, if you have pre-existing diabetes or are at high risk for gestational diabetes, your doctor may use HbA1c tests as part of your overall monitoring strategy. It’s important to work with your healthcare provider to manage blood sugar during pregnancy to ensure the health of both mother and baby.
