A new at-home test for the coronavirus has been approved by the U.S. Food and Drug Administration. The test will cost about $30 and will be available over-the-counter, according to the company who makes it, Ellume. The U.S. Food and Drug Administration Tuesday authorized the first coronavirus test that people will be able to buy at a local store without a prescription and use and get immediate results at home to find out if they're positive or negative. The test will cost about $30 and be available by January, . The FDA had previously authorized other tests that let people avoid long lines by collecting a sample themselves at home. But those tests require people to send the sample to a lab and wait for the results. Another recently authorized test doesn't have to be sent off to a lab, but it requires a prescription to get it.
