Abstract:
116 pregnant women with risk factors of GD M (24 - 28 weeks) were studied and the
patients were allocated in to two groups randomly. OGCT was done (50g) irrespective of
their last meal, venous blood sample were checked with glucometer after one hour in the
first group. Post Parandial Blood Sugar (PBS) (two hour) was done in the second group both
groups were subjected to Oral Glucose Tolerance Test (OGTT) with 75g within seven days
intervals of the first test. Out of 116 pregnant women, 27 [23.3 percent] diagnosed to have
glucose intolerance.] Venous samples of OGCT analyzed by lactometer, having good
positive predictive value (58.3 percent), negative predictive value (100 [percent) and chi -
square test value is 0.001. Cut off value of 130 mg/dl for the OGCT [50g] gives
comparatively lesser values of specificity. (44 percent) positive predictive value (33.3
percentage). Chi square value is 0.02. OGCT (50g) by using glucometer is a usefill
screening test in identifying GDM in pregnancy with cut off value of 140 mg/dl. OGCT-50g
is superior to the PPBS.
