One-Step versus Two-Step Diagnostic Test for Gestational Diabetes Mellitus

Abstract

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.
