This study has shown that there is no significant loss of positive results if spot specimen of sputum is used in place of collection specimen for bacteriological confirmation in the newly diagnosed patients of pulmonary tuberculosis. This appears to be so even in patients with less extensive and non-cavitatory disease. While collection specimen may be used in individual doubtful case, it is not necessary in every patient. Numerically inferior positive results from spot specimen of sputum are more than made up by its other advantages—mainly that it can be obtained easily from every patient attending the clinic. Hence it can be used as a routine for finding bacillary cases amongst newly diagnosed patients in a TB clinic, taking the aid of laryngeal-swab where necessary, for obtaining satisfactory sputum or culturing the swab itself when no sputum is available.
