Affordable TB testing technology developed by ICMR's Assam centre

An affordable tuberculosis testing technology that can detect the disease using a patient's sputum for just Rs 35 has been developed by apex medical research body ICMR's regional centre in Assam's Dibrugarh. The 'A CRISPR case-based TB detection system' is light, portable and involves three steps of testing. Over 1,500 samples can be tested in one single run in around two-and-half hours, ICMR sources said. Conventional diagnostic techniques for TB commonly rely on culture, which requires 42 days to confirm as TB negative, microscopy, and nucleic acid-based methods. These are also time-consuming and may require sophisticated equipment. An official said, "Tuberculosis (TB) remains a global health challenge, necessitating the development of accurate and rapid diagnostic tools for effective disease management. Current diagnostic methods often exhibit limitations in terms of sensitivity, specificity, speed and cost, emphasising the need for innovative approaches". Additionally, some ...
