In epidemiology, the measure of a test's ability to correctly identify those without disease is called what?
Correct Answer:
Specificity
Explanation:
Specificity is the measure of a test's ability to correctly identify those without disease. It equals true negatives divided by the sum of true negatives and false positives (TN / [TN + FP]). A high specificity means few false positives, so a positive result strongly indicates disease being present. Sensitivity focuses on detecting those who have the disease (true positives among all with disease), predictive value deals with the probability of disease given a test result, and prevalence is how common the disease is in the population. Therefore, the described measure is specificity.
