Introduction: The present study aimed to assess OGCT and BSL (fasting and post prandial) as a mode of screening of GDM in pregnancy. The study was intended as there is considerable controversy
regarding the type and timing of test used to screen for GDM. Methods: A total of 500 antenatal patients matching the inclusion and exclusion criteria was taken up for this study. Each subject was asked to consume 75g OGCT and was also asked to do fasting and post prandial blood sugars within 1 week and values were noted and compared. Results: Out of 500 women in the study, 247 had impaired blood sugar parameters as per oral glucose test, in the form of impaired oral glucose test (28%), gestational diabetes (17.4%) and frank diabetes(3.2%). 232 women has impaired fasting levels (46.4%). Astonishingly only 75 women had deranged post prandial values. The correlation of OGCT to BSL fasting was found to have statistical significance with p value 0.01 and as noted in (table), OGCT and fasting BSL have a good correlation. On the contrary the correlation of OGCT with abnormal PP was insignificant. Conclusion: Fasting glucose measurement performs comparably to 75-g OGCT, but post prandial glucose does not.
