May 19, 2021 × ‘Capability to quantify the Covid-19 antibody concentration will be crucial in estimating the declining antibody response over time’ PathShodh Healthcare, a start-up incubated at the Society for Innovation and Development (SID), Indian Institute of Science (IISc), has developed a semi-quantitative electrochemical ELISA test for Covid-19 IgM and IgG antibodies. PathShodh has received the licence to manufacture the test for sale from the Central Drugs Standard Control Organisation (CDSCO), after due diligence validation at the Translational Health Science and Technology Institute (THSTI), Faridabad, as per the requirements of the Indian Council of Medical Research (ICMR). The novelty of the technology is based on the measurement of electrochemical redox activity of IgM and IgG antibodies specific to the SARS-CoV-2 Spike Glycoprotein (S1).
