Glucose, 1-Hour (Post-Challenge) details
What Glucose, 1-Hour (Post-Challenge) shows
This value comes from a three-hour, 100 g oral glucose tolerance test used in pregnancy, usually after an abnormal screening result. After a fasting sample, you drink a solution containing 100 g of glucose, and blood is drawn at one, two and three hours. This is your glucose level at the one-hour point. It helps show how well your body clears a sugar load while pregnancy hormones make insulin less effective. A higher result than expected suggests reduced glucose tolerance. Gestational diabetes is diagnosed from the pattern across all four samples, not from this value alone, using the criteria your clinician follows.
Tests that include Glucose, 1-Hour (Post-Challenge)
This test measures plasma glucose levels to help diagnose and manage carbohydrate metabolic disorders. It's particularly useful for identifying conditions of abnormally high (hyperglycemia) or low (hypoglycemia) blood sugar levels.
- Fasting Glucose Blood sugar measured after fasting, one of the primary tests used to screen for prediabetes and diabetes.
- Glucose, 1-Hour (Post-Challenge) Your blood glucose one hour after the 100 g glucose drink in a four-sample pregnancy glucose tolerance test for gestational diabetes.
- Glucose, 2-Hour (Post-Challenge) Your blood glucose two hours after the 100 g glucose drink in a four-sample pregnancy glucose tolerance test for gestational diabetes.
- Glucose, 3-Hour Your blood glucose three hours after the 100 g glucose drink, the final sample of a pregnancy glucose tolerance test for gestational diabetes.
