Use of Adenosin Deaminase in Diagnosis of Tuberculosis

This research deals with the possibility of assaying the activity of adenosin deaminase (ADA) for Tuberculosis diagnosis. Results indicated that its activity increases by Tuberculosis infection though its level in serum is lower than in pleural effusion samples due to infection by pleural effusion Tuberculosis. The high values of ADA activity on pleural effusion infection, makes this a specific test for Tuberculosis infection rather than total protein test and leucocyte differentiation number which are not specific tests for this case.
