Records were collected in terms of age, gender, contact with TB, vaccination with Bacillus Calmette-Guerin (BCG), albumin, body mass index (BMI), smoking and alcohol intake, presenting complaints, sputum smear
and culture, range of TB disease, lung cavity and its range, course of TB, history of TB treatment, comorbidity, etc.
While efforts were made to merge databases that captured individual patient-level sputum smear
microscopy, Xpert MTB/RIF, and MTB culture results, this was not always technically possible.
Keeping in mind the above facts, the present study was conducted among new smear-positive pulmonary TB patients to identify medicosocial factors associated with a delay in sputum smear
conversion at the end of IP and also the influence of smear conversion on treatment outcome.
Patient 5's treatment continued without further problems; she continued improving clinically, with improved chest radiograph findings and continuously negative sputum smears
Pre-treatment poor glycemic control is associated with a significant increased risk of advanced and more severe TB disease in the form of lung cavitations, positive sputum smear
, and slower smear conversion after initiation of treatment.

microscopy in tuberculosis: is it still relevant?
8% (n=1,725) of the examined TB suspects in intervention districts were sputum smear
positive, compared to 9.
Objectives: To determine the factors affecting sputum smear
conversion time in newly diagnosed pulmonary tuberculosis patients.
positive sputum smear

RNTCP is heavily relying on conventional sputum smear
microscopy (done by Ziehl-Neelsen staining) which is not as sensitive as LED microscopy.
When examining a sputum smear
in SSM or FSSM, the procedure involves not only determining whether or not AFBs are present, but also determining the average number of bacteria found per microscopic field.
