Universal screening for gestational diabetes mellitus (GDM) is advocated in Indian women as they have the highest frequency of GDM, among South Asian population. For this the diagnostic procedure has to be simple, economical and evidence based. Hence, this study was undertaken to compare the point-of-care measuring capillary blood glucose (CBG) by glucometer and venous plasma glucose (VPG) estimated in the laboratory and to suggest the feasible diagnostic tool. Consecutive pregnant women in the third trimester were included in this study with the approval of the institutional ethical committee. They were given 75 g oral glucose in the fasting state. After 2 hours, CBG was measured by finger-prick using one touch select simple glucometer and venous blood was drawn to estimate VPG in the laboratory by GOD- POD method. The diagnosis of GDM was based on 2 hours plasma glucose > or = 7.8 mmol/l. Among a cohort of 500 pregnant women, 32 (6.4%) were diagnosed as GDM in their first visit. The CBG value at 2 hours plasma glucose > or = 7.8 mmol/l had a sensitivity of 93.8% and specificity of 97.4% with a false positive and false negative of 2.6% and 6.2%, respectively. The area under the receiver operating characteristic curve of CBG was 0.993. CBG value at 2 hours plasma glucose > or = 7.8 mmol/l may be recommended for the diagnosis of GDM in healthcare centres where laboratory technology is not available.
