Investment bank Goldman Sachs has predicted that US monthly coronavirus antigen test capacity could jump 600% as new tests hit the market.
US antigen testing capacity stands at 32 million tests per month, but the bank’s analysts think the four currently approved antigen tests will reach a capacity of 70-75 million per month before the end of 2020 and 82 million by mid-2021.
