ANTENATAL SCREENING FOR DIABETES MELUTUS BY RANDOM BLOOD GLUCOSE SAMPLING

Abstract
A system is decribed for screening an antenatal population for diabetes mellitus based upon random blood glucose sampling. Samples obtained from 186 healthy pregnant women at 28 wk gestation provided a range of blood glucose concentrations after normal meals from which it was possible to derive 2 glucose values to define an upper limit of normality. The first, 6.4 mmol/l if within 2 h of eating and the 2nd, 5.8 mmol/l when taken more than 2 h postprandial were prospectively applied to the screening of 763 consecutive antenatal patients. Ten women exceeding these limits were referred for an oral glucose tolerance test and 3 had a diabetic response, an incidence of about 4 undiagnosed diabetic women per 100 antenatal population.
