rapid diagnostic tuberculosis tests in the study missed more
cases than they found Open Society Institute/Pep Bonet An
inquiry into some tuberculosis tests on sale to developing
countries has found that most were missing more cases than they
found. The evaluation of 19 commercially available rapid
diagnostic tests, which detect antibodies to tuberculosis
bacteria, found that on average they could identify only about a
