Researchers with the Swiss-based Quotient blood screening company say they have developed a COVID-19 antibody test that will quickly and accurately determine whether test subjects have developed antibodies that will make them immune to viruses.
In an interview with the French news agency Agence France-Presse, Quotient Chief Executive Franz Walt said the test had been shown to have 100% sensitivity and 99.8% specificity claims, which would make it one of the most accurate tests for COVID-19 available
Walt said the test was developed jointly by scientists working in Edinburgh, Scotland, and at the Quotient headquarters in Switzerland. He said the test runs on an instrument called Mosaic which can provide an initial test in 35 minutes, with subsequent results every 24 seconds. After that, up to 3,000 tests per day can be sent.
An accurate antibody test will be a valuable tool to end the lockdown, because it can identify people who can’t get the virus and don’t infect others.
The company said the European Union had an interest in testing and the machines that run it. The BBC reports the company is also interested in negotiations with the UK.
