OBJECTIVE: To compare the 50 g oral glucose tolerance test with capillary sampling used in the Mercy Hospital for Women, Melbourne with the 75 g test with venous sampling advocated by the Australasian Diabetes in Pregnancy Society. METHODS: Both the 50 g and 75 g glucose tolerance tests were performed on 60 women. Criteria for diagnosing gestational diabetes were the combination of a 1-hour capillary plasma glucose > or = 9 mmol/l and a 2-hour glucose > or = 7 mmol/l for the 50 g test and a fasting glucose > or = 5.5 mmol/l and/or a 2-hour venous plasma glucose > or = 8.0 mmol/l for the 75 g test. RESULTS: Twenty-eight of 60 women had gestational diabetes diagnosed with the 50 g test; 24 of these, and an additional 5 had gestational diabetes diagnosed on the 75 g test. Twenty-seven women had normal results on both tests. The kappa statistic was 0.70. The 1-hour glucose value was similar for both tests, but the 2-hour value was significantly higher for the 75 g test (mean difference 0.65 mmol/l, 95% confidence limits 0.24-1.01 mmol/l, p = 0.003). The area under the curve was similar for the 2 tests. CONCLUSIONS: The 2 tests diagnose similar women as having gestational diabetes. The combination of a 75 g load and venous sampling gives similar 1-hour but higher 2-hour values than a 50 g load and capillary sampling. |
