Tuberculosis (TB) is responsible for 1.4 million deaths annually. Wide-spread misuse of anti-tubercular drugs over three decades has resulted in emergence of drug resistant TB including multidrug-resistant TB and extensively drug-resistant TB globally. Accurate and rapid diagnosis of drug-resistant TB is one of the paramount importance for instituting appropriate clinical management and infection control measures. The present article provides an overview of the various diagnostic options available for drug resistant TB, by searching PubMed for recent articles. Rapid phenotypic tests still requires days to weeks to obtain final results, requiring biosafety and quality control measures. For newly developed molecular methods, infrastructure, training and quality assurance should be followed. Successful control of drug resistant TB globally will depend upon strengthening TB control programs, wider access to rapid diagnosis and provision of effective treatment. Therefore, political and fund provider commitment is essential to curb the spread of drug resistant TB.
