National Environmental Engineering Research Institute (Neeri) has come up with a path-breaking innovation for Covid testing. It has developed a technique of collecting samples through gargling and then testing it under RT-PCR is a world first. It has got approval from the Indian Council of Medical Research (ICMR). Under the new technique, no RNA extraction is necessary as is the case with existing testing of samples. Even though the RT-PCR procedure remains the same, potentially the suspected patient can get the test result faster. Krishna Khairnar, the scientist who brought about this innovation, informed us that this is a simpler and faster technique for RT-PCR testing. 'We have been working on this technique for almost a month. Gargling is one of the commonly used methods to tackle the upper respiratory infection. We thought why not use the same method to trap the virus,' he said. Khairnar is a scientist and head of environmental virology cell at Neeri.
