(b) Table Q1 below provides the results from a study of a rapid diagnostic test for tuberculosis (TB). Calculate its sensitivity and specificity. What is the likelihood that a patient tested positive with this test is infected with TB ? Groups TB Non-TB Healthy Controls Total Trustline kit, n Positive Negative 385 53 24 462 243 166 138 547 Table Q1: Clinical performance of the Trustline diagnostic kit for tuberculosis (TB). (non-TB patients are sick patients, but that do not suffer from TB). Taken from Eur J Clin Microbiol Infect Dis (2014) 33:1989-1994 Solution: Sensitivity = 61% Specificity = 79% positive predictive value 83%. So roughly out of 10 positive results, 8 patients will actually have the disease. 2 patients will be wrongly diagnosed.
