The first home test for COVID-19 that doesn’t require a prescription will soon be on U.S. store shelves. U.S. regulators Tuesday authorized the rapid coronavirus test, which can be done entirely at home. The announcement by the FDA represents another important — though incremental — step in efforts to expand testing options. Regulators granted emergency use for a similar home test last month, but that one needs a doctor’s prescription. … Initial supplies of the over-the-counter test will be limited. Australian manufacturer Ellume said it expects to produce 3 million tests next month before ramping up production over the first half of 2021. A company spokesperson said the test will be priced around $30 and be available at pharmacies and for purchase online.
