Comparison of Single-Test Point-of-Care Results with the Reference Laboratory Tests
Laboratory Positive Laboratory Negative POC positive 1 11 Positive predictive value: 8.3% POC negative 0 840 Negative predictive value: 100% Sensitivity: 100% Specificity: 98.7% Note: Analysis of 852 samples with valid test results on both the single-test point-of-care (POC) and laboratory real-time polymerase chain reaction (RT-PCR) test (see discussion in the text). Laboratory RT-PCR testing served as the definition of disease in this analysis. Sensitivity is defined as the proportion of true-positive results among all positive results. Specificity is defined as the proportion of true-negative results among all negative results. Positive predictive value is the proportion of true-positive results among all positive test results. Negative predictive value is the proportion of true-negative results among all negative results.
