Retrieved from ” https: Polymerase chain reaction for rapid diagnosis of tuberculous meningitis in AIDS patients. Evaluation of polymerase pcr anidada reaction for rapid diagnosis of clinically suspected tuberculous meningitis. According to the authors, false-negative results can be detected through the inclusion of a control-positive reaction.

Controls Three different controls were included in PCR reactions. The incidence rate varies from 14 to 70 cases perinhabitants, according to the different pcr anidada regions. All patients had image data radiological or CT scans with minor changes, the most frequent of these being the presence of pulmonary nodules pcr anidada opacities. We conducted a study of pcr anidada PCR tests in 45 patients and a review of patient hospital files, calculating pcr anidada, specificity, positive predictive value PPVand negative predictive value NPV.

On the other hand, no amplification was obtained when we tested the samples from group b. Books at your local library about nested polymerase chain reactions Scholarly articles on nested polymerase chain pcr anidada. In order to evaluate the performance of nested-PCR we used as gold standard the criteria employed by the health services in the diagnostic definition of TB such as the combination of epidemiological, clinical and laboratory data chest X-ray, tuberculin test, sputum smear or culture and patient history.

However, in children with pneumonia, blood culture yields a sensitivity lower than 10 per cent due to the most of them presents no bacteraemia pcr anidada, 16 or due to a previous antibiotic therapy.
