Background: The aim of the study was to correlate between first trimester uric acid level and its association with subsequent development of gestational diabetes mellitus.Methods: This is a prospective study conducted at Govt. Raja Mirasudar Hospital attached to Thanjavur Medical College, Thanjavur over a period of one year from September 2015. A total of one hundred and eighty seven ante natal women less than 14 weeks of gestational age who attended the outpatient antenatal department were included in this study. Serum uric acid estimation was done in women with 3.6 mg/dl and 2 with serum uric acid <3.6 mg/dl developed GDM. This shows development of GDM increases with increase in uric acid concentration.Conclusions: Though our study results suggest that serum uric acid level estimation in first trimester can be used as a marker to predict GDM in pregnant women, large scale studies are required before it can be recommended as a routine first trimester screening test for prediction of gestational diabetes mellitus
