Decentralization of Acid Fast Bacilli(AFB) External Quality Assurance Using Blind Rechecking for Sputum Smear Microscopy in Ethiopia
INTRODUCTION Ethiopia achieved a rapid expansion of TB microscopic centers for acid fast bacilli (AFB). However, external quality assurance (EQA) services were, until recently, limited to few regional and sub-regional laboratories. In this paper, we describe the decentralization experience and the result of EQA using random blinded rechecking. MATERIALS AND METHODS The routine EQA quarterly r...
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...

conclusion fm is more sensitive than zn for diagnosis of tb. however, since fm is more sensitive and rapid, using this method in clinical laboratories with large specimen numbers is recommended. results a total of 102 out of 920 study subjects had pulmonary tb, of them 68 (66.66%) patients were smear positive by either staining method while others were smear negative. the proportion of positive...
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 کاملEvaluation of a Cold Staining Method for Detecting Acid Fast Bacilli in the Sputum
Tuberculosis is a disease of great importance in developing countries, such as India, where it has caused considerable morbidity and mortality. Sputum smear microscopy is the cornerstone in diagnosis of pulmonary tuberculosis, which is usually done using Ziehl–Neelsen (ZN) method (Vasanthakumari et al., 1986; Gupta et al., 2009; Chandrasekaran et al., 1991). The use of ZN Method in remote areas...
