Screening of Gestational Diabetes Mellitus with Glucose Challenge Test in High Risk Group

摘要

The present study of screening for gestational diabetes mellitus was carried out in 480 high risk women attending Suvidha Mother & Child Nursing Home. The patients underwent glucose challenge test with 50 gm glucose (GCT ) using glucometer, between 18-20 weeks and if negative the test was again done after 28 weeks. All the 120 patients with abnormal GCT were subjected to 3 hours 100gm oral glucose tolerance test (OGTT ) and 49 patients were found to have abnormal GTT. 3.05% of women were found to have gestational diabetes . Sensitivity of glucose challenge test in detection of gestational diabetes in high risk group was 40.5% The incidence of PIH in patients with abnormal GCT was 22.5%.Since screnning of high risk group was done with the help of glucometer it required no extra laboratory facilities, long waiting period or trained manpower. It has no side effects and guarantees good compliance of patient. GCT hence is a reliable method to detect gestational diabetes mellitus in high risk group.
