PathShodh Healthcare has developed a breakthrough semi-quantitative electrochemical ELISA test for Covid-19 IgM and IgG antibodies. The Indian Central Drugs Standard Control Organisation (CDSCO) has granted the start-up a licence to manufacture the test for commercial use, after validation at the Translational Health Science and Technology Institute (THSTI), and according to Indian Council of Medical Research (ICMR) requirements.

Online food ordering and delivery platform DoorDash has collaborated with Vault Health to deliver same-day Covid-19 tests in Cleveland. The at-home test kits have to be ordered before 1 p.m., while patients will receive an email to track the delivery. A Vault staff is also expected to remotely supervise the use of the test, confirm the identity of the individual, guide users in collecting the right amount of saliva, and to answer their queries. The test results can be expected within a day at the partner lab.

The US Food and Drug Administration (FDA) issued a safety statement warning the public not to rely on the results from SARS-CoV-2 antibody tests to determine their immunity or protection against Covid-19. The FDA will be continuously evaluating authorised SARS-CoV-2 antibody tests for other purposes.
