What Is A Glucose Challenge Test?
A GCT or Glucose Challenge Test is a blood test drawn at 28 weeks (7 months) of pregnancy to screen for gestational diabetes. All pregnant patients should be screened in the late second trimester and a positive screening test must then be followed by a Glucose Tolerance Test or GTT. A GTT is the diagnostic test for gestational diabetes and a positive test means gestational diabetes is present. After diagnosis, a special diet and exercise will be recommended.
