Tuberculosis screening: usefulness of new KREATECH IgA ELISA test.
A total of 71 sera from 15 proved cases of pulmonary tuberculosis, 2 cases with doubtful radiological report and 54 suspected cases, contacts, donors etc. were subjected to Elisa IgG, IgM and IgA tests for tuberculosis, with a view to comparing the merits of IgA test with those of IgG and IgM. Kreatech IgA test which is claimed to indicate presence of active tuberculosis was positive in 13 of the proved cases and negative in both the doubtful cases. These preliminary results indicate that KREATECH IgA is a promising new ELISA test which can be a useful laboratory aid in the diagnosis of active tuberculosis, both pulmonary and extrapulmonary, for screening of suspected cases, and for monitoring cases undergoing therapy.
