PREVALENCE OF POSITIVITY OF CBNAAT IN EXTRA PULMONARY TUBERCULOSIS

Abstract

Background: TB is the 9^th leading cause of death worldwide and the leading cause from a single infectious agent. It is estimated  that 15 to 20% of all TB cases are extra pulmonary.

Methods: This study conducted on Patients of EPTB diagnosed on the basis of clinico radiological basis attending the OPD. Patients with signs and symptoms and radiological examination suggestive of extra-pulmonary tuberculosis were included in this study.

Results: In present study 16(64.00%) patients suggestive of TB by FNAC were CBNAAT positive and 9(36.00%) were CBNAAT negative. 5 patients (45.45%) were NOT suggestive of TB by FNAC were CBNAAT negative and 6(54.55%) were CBNAAT positive. This difference however is not found to be statistically significant (p=0.869).

Conclusion: Present study revealed that more positivity rate by CBNAAT in comparision to smear staining in pleural fluid which indicate that it is a more sensitive technique as compared to conventional methods.
