The Glucose Challenge Test (GCT) is a screening test used to assess how your body handles sugar and is commonly used to screen for gestational diabetes during pregnancy. It typically involves two samples:
Fasting Sample: A blood sample is taken after an overnight fast to measure your baseline blood sugar levels.
2-Hour Post-Glucose Sample: After consuming a sugary drink (usually containing 50 grams of glucose), a second blood sample is taken two hours later to see how your body processes the glucose.
