Lot quality assurance sampling of sputum acid-fast bacillus smears for assessing sputum smear microscopy centers.
Assessment of 12 microscopy centers in a tuberculosis unit by blinded checking of eight sputum smears selected by using a lot quality assurance sampling (LQAS) method and by unblinded checking of all positive and five negative slides, among the slides examined in a month in a microscopy centre, revealed that the LQAS method can be implemented in the field to monitor the performance of acid-fast...
متن کاملRelationship between CT Findings of Pulmonary Tuberculosis and Acid-Fast Bacilli Sputum Smears
Background and purpose: Computed tomography (CT) scan is of great help in confirming the diagnosis of tuberculosis (TB) before the sputum test result. The purpose of this study was to investigate the relationship between pulmonary involvement patterns in CT scans of TB patients with positive sputum smears. Materials and methods: This retrospective descriptive-analytical study was conducted usi...
متن کاملEvaluation of sputum smears concentrated by cytocentrifugation for detection of acid-fast bacilli.
Early identification and isolation of tuberculosis patients is of utmost importance to minimize the risk of further epidemic spread of the disease. The traditional concentrated acid-fast smears are not very reliable tools for the presumptive diagnosis of tuberculosis. Acid-fast bacillus (AFB) smears from 120 patients specimens and 80 simulated AFB samples were processed according to standard la...
متن کاملImproved method of direct microscopy for detection of acid-fast bacilli in sputum.
Microscopy of direct smears for acid-fast bacilli (AFB) is the most commonly used method for diagnosis of tuberculosis. However, direct microscopy of sputum, though rapid, has low sensitivity and there is a need for improved methods. Sputum samples were collected from patients attending the Union Tuberculosis Institute, Yangon. The microscopy of smears made directly from sputum were compared wi...
متن کاملComparison of machine and manual staining of direct smears for acid-fast bacilli by fluorescence microscopy.
Comparisons were made in Lusaka and in London between manual staining and staining in an automatic machine with auramine-phenol of direct smears of sputum and other types of specimen for acid-fast bacilli. No evidence was obtained of carry-over of acid-fast bacilli from positive to negative smears during machine staining. There was improved contrast between bacilli and the background in smears ...
