Innovita test verified Good
Accuracy assessments
Several groups are now independently evaluating antibody tests for these measures. One study, dubbed the COVID-19 Testing Project and run by physicians and researchers at institutions including the University of California, San Francisco (UCSF), the University of California, Berkeley (UCB), Massachusetts General Hospital (MGH), and the Chan Zuckerberg Biohub, evaluated 10 LFAs and two ELISAs. To assess their ability to identify antibodies against SARS-CoV-2, the team used plasma or serum samples from three groups: 80 people who had shown symptoms of COVID-19 and had tested positive using a PCR-based screen, 52 who had a respiratory infection but were found to be infected with another virus or had tested negative on a PCR test for SARS-CoV-2, and 108 blood donors whose samples were drawn in 2018 or earlier, before the pandemic began.
According to the The New York Times, one of the tests examined in the study, by the Chinese company Innovita, has been ordered by Los Angeles–based start-up Scanwell Health, which hopes to market the product for at-home use, pending FDA authorization. That test identified antibodies in up to 83 percent of people with confirmed infections and has a specificity of 96 percent. https://www.the-scientist.com/news-opinion/why-the-accuracy-of-sars-cov-2-antibody-tests-varies-so-much-67513
