Accuracy of Screening Tests

Three tests have been used to screen for diabetes: fasting plasma glucose (FPG), 2-hour post-load plasma glucose (2-hour PG), and hemoglobin A1c (HbA1c). Sensitivity and specificity are in the range of 75% to 80% for all three tests using these thresholds: FPG = 126 mg/dL, 2-hour PG = 200 mg/dL, and HbA1c = 6.4% (Harris et al., 2002). The American Diabetes Association (ADA) has recommended the FPG or 2-hour PG test for screening; the FPG is easier and faster to perform, more convenient, and acceptable to patients, and it is less expensive than other screening tests. The FPG is also more reproducible than the 2-hour PG test and has less intraindividual variation.
