Clinical usefulness of the nested polymerase chain reaction in the diagnosis of extrapulmonary tuberculosis.
OBJECTIVE To evaluate the effectiveness of nested polymerase chain reaction (PCR) for diagnosis of extrapulmonary tuberculosis (ETB), as well as the impact of PCR results on clinical management. MATERIALS AND METHODS We conducted a study of nested PCR tests in 45 patients and a review of patient hospital files, calculating sensitivity, specificity, positive predictive value (PPV), and negativ...
متن کاملPolymerase Chain Reaction for the Diagnosis of Tuberculosis
Dear Editor-in-Chief We read with interest the study by Khazaei et al. (1) in which the authors have nicely concluded that PCR is more sensitive test than Ziehl-Neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (TB). They have rightly pointed to use PCR, selectively, in acidfast bacilli negative paucibacillary forms of TB. However, we intend to highlight few...
متن کاملClinical utility of the polymerase chain reaction in the diagnosis of extrapulmonary tuberculosis.
This study examines the diagnostic utility of the polymerase chain reaction (PCR) in 156 patients (five human immunodeficiency virus (HIV) seropositive) suspected of extrapulmonary tuberculosis. The results of PCR in 226 samples from 11 different sites were compared with the results of microscopy and culture. Positive culture results were predicted in 86% of samples by PCR but in only 31% by mi...
