Abstract

Concurrent testing with 1 TU RT XXIII with tween 80, 5 IU PPD-S and 10 TU PPD-B in North Indians aged 15 years and above attending a Tuberculosis Centre because of their symptoms suggestive of pulmonary tuberculosis was under-taken to find out the value of dual antigen testing with a standard tuberculin and an antigen prepar-ed from an atypical myco-bacterium. Dual antigen testing was found to be helpful in deciding higher and lower risk groups amongst persons classified as infected by a standard tuberculin test. For such a purpose dual testing with 5 IU PPD-S and 10 TU PPD-B appears to be more specific than dual testing with 1 TU RT XXIII and 10 TU PPD-B. Significantly lower tuberculosis case rate was observed among symptomatics having infection with myco-tuberculosis perhaps with the presence of atypical infection, as compar-ed to those possibly infected with myco-tuber-culosis alone; this might be due to the protection offered by non-specific sensitivity against myco-bacterium tuberculosis.
