Women with type 1 or type 2 diabetes, HbA1C \u22656.5%, and\/or fasting plasma glucose \u2265126\u00a0mg\/dL were excluded, as were women whose glucose levels had already been tested before 24\u00a0weeks of pregnancy. Data were extracted from a maternal and neonatal database. The primary outcome measure was the association between first trimester HbA1C and adverse pregnancy outcome, primarily, gestational diabetes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The cohort included 142 women. HbA1C concentration was linearly and inversely correlated to length of gestation (r=\u22120.317, <jats:italic>P<\/jats:italic>&lt;0.001). Higher HbA1C was associated with gestational diabetes. An HbA1C concentration of \u22655.45% predicted gestational diabetes with 83.3% sensitivity, 69% specificity, and gave positive and negative predictive values of 53% and 90.8%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Early pregnancy HbA1C could serve as a predictor of gestational diabetes.
