Es suggestive of PTB and only three patients of these were subsequently discovered to possess culture positive PTB.To our understanding, there have been at the very least 3 research which have examined the sensitivity of consecutive smears.Nelson et al. discovered that only in the third samples were positive when the very first two smears have been unfavorable, while Siddiqui et al. reported a related rate of .A metaanalysis by Burken et al. concluded that the sensitivity of two AFB smears was the exact same as that of three AFB smears for the diagnosis ofTable Comparison of TB culture constructive and culture adverse patientsPositive TB Culture (N ) Mean Age yr Symptomatic no.
