Aim: Comparison between one-step Diabetes in Pregnancy Study Group India (DIPSI) and American Diabetes Association (ADA) recommended two-step oral glucose tolerance test (OGTT). Material and methods: This study has a sample size of 200; 100 participants each were subjected to either of the two tests. Gestational diabetes mellitus (GDM) and non-GDM diagnosed by one-step test versus two-step test, respectively, were compared to one another and results were compared on the basis of various antenatal complications and fetomaternal outcomes. Results: No statistical difference was found between both the groups on the basis of various antenatal and fetomaternal outcomes. Conclusion: In Indian subcontinent with poor resources and lack of follow-up, single-step DIPSI can be preferred to ADA recommended two-step OGTT; however, large database studies are still required
