Included in the complete list are sensitivity and specificity measures, specimens required, target genes, and test details. If individuals who have the condition are considered "positive" and those who don't are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives: 2021 Mar 24;3(3):CD013705. AN, anterior nasal;, Participant flowchart. FOIA Seiler LK, Stolpe S, Stanislawski N, Stahl F, Witt M, Jonczyk R, Heiden S, Blume H, Kowall B, Blume C. BMC Public Health. These rapid tests detect basic levels of antigen already present in a sample, providing only a simple yes or no, similar to a pregnancy test. Sensitivity and specificity are measures that are critical for all diagnostic tests. It can be calculated using the equation: sensitivity=number of true positives/ (number of true positives+number of false negatives).
