Increased detection of smear-negative pulmonary tuberculosis by GeneXpert MTB/RIF ® assay after bleach concentration

Conclusion Testing of a single sputum sample by Xpert can reach reasonable sensitivity and results would be available on the same day, avoiding loss of patients and treatment delay. The sensitivity of Xpert was improved after bleach concentration and pelleting, although its added value needs further study on a larger scale.
