The sensitivity, specificity, positive predictive value and negative predictive values of TB PCR, using TB culture as the gold standard were 90%, 91.6%, 78.3%, and 96.5% respectively. The sensitivity, specificity, positive predictive value, and negative predictive values of TB PCR for detecting rifampicin resistance, using TB culture and sensitivity as the gold standard, were 33%, 100%, 100%, and 95%, respectively. Overall, the accuracy of TB PCR in detecting TB disease is 91.2% and the accuracy of TB PCR in detecting rifampicin resistance is 95%.<\/div>\n<div class=\"volume\"><strong> Conclusion:<\/strong> Findings in our study suggest that TB PCR play an important role in TB disease diagnosis, but clinical and radiological assessment continue to be essential in the diagnosis of childhood tuberculosis. The accuracy of TB PCR in detecting TB disease in children is 91.2% and the accuracy of TB PCR in detecting Rifampicin resistance is 95%.<\/div>\n<p><a href=\"https:\/\/doi.org\/10.56964\/pidspj20171802004\"><strong>https:\/\/doi.org\/10.56964\/pidspj20171802004<\/strong><\/a><strong>\u00a0<\/strong><br \/>\n<strong><a href=\"https:\/\/www.pidsphil.org\/home\/wp-content\/uploads\/2018\/12\/jo53_ja04.pdf\" target=\"_new\" rel=\"noopener\">View Full Article in PDF format<\/a> |<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Journal 2017 Vol.18 No.2 A Retrospective Study on Sensitivity, Specificity, Negative Predictive Value, Positive Predictive Value of TB PCR Versus TB Culture in Diagnosing Tuberculosis in Filipino Children Aged 3 Months to 18 Years at a Tertiary Care Center Jesanel B.
