In March, the FDA relaxed their standards by allowing companies to sell antibody testing without proving that the tests worked. After this resulted in poor quality tests flooding the market, the FDA has reconsidered their options and decided that government scientists must now review the tests before they enter the market. Antibody testing can lead people to think they are immune from Covid-19, so it is crucial that these tests yield accurate results. For this reason, all antibody tests will now undergo scientific approval, in order to obtain correct results and prevent further inaccurate tests from entering the market.
