Long-Term GeneXpert Positivity after Treatment for Pulmonary Tuberculosis

Abstract

GeneXpert assays have a pivotal role in the diagnosis of tuberculosis (TB), with overall good sensitivity and excellent specificity.Patients with a history of TB can be GeneXpert positive up to several years after the end of appropriate antitubercular treatment.Further studies are warranted to fully understand the role of GeneXpert assays in the diagnostic algorithms of patients with a history of TB.
