Quantitative test methods must be validated based on accuracy, precision, sensitivity, specificity, predictive value, and efficiency before a decision is made. Sensitivity is the percentage of individuals with the particular disease for which the test is used in whom positive test results are found. These are also called True-positives. Tests with very high sensitivity (99%) can, if negative, be used to exclude the presence of disease. For example, if an RSV direct antigen test is negative and the test sensitivity is 99.9%, then the infant is unlikely to have RSV. Most tests will show some False-positive results; these represent cases in which individuals without the particular disease test positive by a certain test.
