ABSTRACT
This study compared 2 screening tests for detecting undiagnosed diabetes mellitus when applied in a mass-screening campaign in the Eastern province of Saudi Arabia in 2004-05. Of 15 082 individuals screened, 65.8% were positive by the American Diabetes Association risk-score questionnaire and 71.3% by determination of capillary blood glucose [CBG] using a portable glucometer. Type 2 diabetes mellitus was confirmed in 20.3% of participants and pre-diabetes in 33.9% using fasting venous blood testing. The risk-score questionnaire did not perform well versus fasting and random CBG. Optimal cut-offs for fasting and random CBG were 120 mg/dL and 160 mg/dL respectively. Fasting CBG had higher sensitivity, specificity and discriminating ability than random CBG for detection of diabetes and pre-diabetes in this population
