Without a tuberculosis diagnosis, many were not followed up because of this disease. MDR tuberculosis developed in some of these patients if they took their medicines improperly. Recently, the WHO recommended the use of the GeneXpert program to evaluate individuals who are suspected to possess MDR tuberculosis and those with unfavorable sputum smears for acid-fast bacilli.30,31 The use of this diagnostic program can offer a definitive medical diagnosis for nearly all patients with pulmonary tuberculosis.Kaiser Family Foundation.
