Brief Summary:

Gestational Diabetes Mellitus (GDM) is a common metabolic complication of pregnancy defined as new onset hyperglycemia during gestation. GDM conveys significant risk of morbidity and mortality for both mother and infant. An estimated 268,900 infants were born to mothers with GDM in the USA, accounting for approximately 6.9% of births. Although individual correlations have been found between elevated GGT and uric acid levels and later development of GDM, no research has established and validated combined criteria for GGT and uric acid levels that would lead to their use in identifying women at high risk of GDM in the first trimester.

Central Hypothesis: Serum GGT and serum uric acid collected between >9-14.0 weeks gestation will be significantly elevated in women who later develop GDM compared to those who do not. Combined analysis of serum uric acid and GGT levels within the first trimester allows for accurate prediction of the development of GDM.

Study population includes women between 9-14 weeks gestation undergoing a standard first trimester blood draw. Additional blood will be drawn during the standard blood draw to assess GGT and uric acid levels. Research participants will be tracked afterwards to determine whether they tested positive for gestational diabetes during the standard testing process which typically occurs at 24-28 weeks gestation. The data will then be analyzed to estimate the sensitivity, specificity, positive and negative predictive values of the first trimester GGT and uric acid tests. The GGT and uric acid levels which maximize the area under the receiver-operator characteristic curve will be identified.
