A random plasma glucose method for screening for gestational diabetes.

ABSTRACT

Low renal threshold for glucose during pregnancy renders glycosuria less specific for the diagnosis of gestational diabetes. Screening for gestational diabetes was done by utilising random plasma glucose (RPG). RPG was done at the first antenatal visit. In 12,623 patients who registered for antenatal care at the N.W.M. Hospital, 1371 patients had a RPG more than 100 mg%. An oral glucose tolerance test was advised in these patients. The pick-up rate of gestational diabetes correlated with RPG level. Thirty-six cases of gestational diabetes were picked up. The pick up rate is significantly higher as compared to that which would have been detected utilising conventional screening criteria.
