Summary:Objective: To determine the prevalence of Tuberculosis and MDR Tuberculosis by GeneXpert assay in Tehsil Hazro District Attock.  Study design: cross sectional study Place and duration of study: Study was carried out at THQ hospital Hazro of District Attock from January 2019 to December 2020 Patients and Methods: Total 1460 patients of TB suspect were included in the study. First LED microscopy of all TB suspects was done. LED Microscopy positive cases along with suspects having history of HIV, close contacts of MDR TB, all TB cases of retreatment and sputum-negative cases of LED microscopy having positive clinical findings were sent for GeneXpert Assay. Results from the GeneXpert assay were categorized as GeneXpert positive, GeneXpert negative, and MDR Tuberculosis. Determinants of MDR- TB were identified using questionnaires regarding MDR –TB. Results: Out of total 205 patients on GeneXpert Assay, 43 patients were GeneXpert positive test with no rifampicin resistance, 3 patients were GeneXpert positive with rifampicin resistance and 63 patients were GeneXpert negative but sign and symptoms, X-ray findings and laboratory tests were supporting tuberculosis and according to opinion of TB specialist they were labeled as Sputum negative Tuberculosis. Tuberculosis prevalence in Tehsil Hazro was 0.073. From the results, it was concluded that an overall MDR rate was 2.7% in our study population. Conclusion: GeneXpert Assay is a rapid technique and reliable for Mycobacterium detection. The main determinants of MDR-TB were the patients who had contact h/o with MDR cases and those who did not follow the treatment regime in their previous Tuberculosis treatment.   Keywords: GeneXpert Assay, LED microscopy, MDR Tuberculosis, Sputum positive TB, Sputum negative TB.
