Es suggestive of PTB and only 3 individuals of those have been subsequently located to possess culture good PTB.To our know-how, there happen to be at least three research which have examined the sensitivity of consecutive smears.Nelson et al. found that only of the third samples have been positive when the first two smears have been adverse, when Siddiqui et al. reported a comparable price of .A metaanalysis by Burken et al. concluded that the sensitivity of two AFB smears was the identical as that of 3 AFB smears for the diagnosis ofTable Comparison of TB culture constructive and culture damaging patientsPositive TB Culture (N ) Imply Age yr Symptomatic no.
