title: The usefulness and cost of a shorter duration of fasting in workplace screening for glucose intolerance and metabolic syndrome.
abstract: For worksite biometric screening, we shortened traditional fasting instructions to 4h. The positive predictive value (PPV) of elevated capillary glucose test results (> or =100mg/dL) for predicting elevated values obtained on repeat testing after an 8h fast was 57%, which rivals the PPV of an 8h fasting glucose.
