A universal screening which is simple, feasible, acceptable and a single step procedure is applicable in Indian scenario as Indian women have an eleven fold increased risk of developing glucose intolerance during pregnancy. When compared to Caucasian women and also among ethnic group in south Asian countries, Indian women have the high frequency of GDM [12].
Seshiah et al., recommended DIPSI as a single step procedure irrespective of the last meal. Pregnant women attending the antenatal OPD were given 75g anhydrous glucose in 250-300ml of water and plasma glucose was estimated after 2 hour. A 2-hours plasma glucose ≥ 140 mg/dl is taken as GDM. [13] However, the cut off has not been put to test to find the correlation with adverse perinatal outcome. A value of ≥ 200 mg/dl as DM and ≥ 120 mg/dl as decreased gestational glucose tolerance (DGGT) has been suggested [Table/Fig-1].
