+ve predictive value was 87.9%.<br />
Table (17) shows that, specificity and +ve predictive value was<br />
improved when measured for combined <strong>symptoms</strong> and CXR and tuberculin<br />
test as for (Cough + expectation and weight loss) combined specificity was<br />
78.1% and +ve predictive value <strong>of</strong>90.6% and when combined with typical<br />
CXR was 90.6%, 94% respectively while combined manifestations that<br />
only presented in smear +ve cases had a specificity, sensitivity, negative<br />
and <strong>positive</strong> predictive value <strong>of</strong> 100%, 7.8%, 18.4%. and 100%.<br />
