RESUMO
This study was carried out on 80 tuberculous patients [pulmonary, extrapulmonary or combined tuberculosis] and 30, age and sex matched healthy subjects as a control group. The aim was to evaluate the diagnostic value of BCG test in adulthood tubercubus patients and comparing it with tuberculin test. All subjects were tested with purified protein derivative and BCG vaccine. The study showed that. the BCG test was positive in 77 patients [96.34%] while tuberculin test was only positive in 52 patients [65%]. In the contrary BCG test was positive in 3 healthy control subjects [10%] while tuberculin test was positive in only two healthy subjects [6.6%]. It can be concluded that BCG test is more reliable and sensitive than the tuberculin test in diagnosis of tuberculosis specially in malnourished and immunocom-promised patients. Furthermore BCG test is safe if it is injected properly
