This inaccuracy is more likely to occur early in the infection in people who display no symptoms.<\/li>\n<li aria-level=\"1\">\u201cCurrently, all at-home COVID-19 antigen tests are FDA-authorized for repeat, or serial use. This means people should use multiple tests over a certain time period, such as 2-3 days, especially when the people using the tests don\u2019t have COVID-19 symptoms,\u201d the FDA said.<\/li>\n<\/ul>\n<p>People should keep multiple tests on hand for the purpose of this new guidance, the agency said. Most over-the-counter, at-home COVID-19 tests are sold in multipacks.<\/p>\n<p>&nbsp;<\/p>\n<p>The guidance:<\/p>\n<ul>\n<li>The FDA recommended that people take one initial test if they suspect they may be infected or exposed to COVID-19. If they test negative and have some symptoms, then they should test again 48 hours after the first test. If the second test is still negative, a laboratory molecular-based test should be considered.<\/li>\n<li>If a person has no COVID-19 symptoms but believes they have been exposed to the virus, the FDA said they should also test themselves a second time, also 48 hours after their first at-home test. If the second test is negative, they should take an additional third test another 48 hours afterward.<\/li>\n<\/ul>\n<p>If any of these at-home tests come back positive, then the individual likely has COVID-19 and should follow guidance from the Centers for Disease Control and Prevention.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Food and Drug Administration (FDA)&#46;&#46;&#46;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[],"class_list":["post-51324","post","type-post","status-publish","format-standard","hentry","category-health"],"_links":{"self":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/51324","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=51324"}],"version-history":[{"count":1,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/51324\/revisions"}],"predecessor-version":[{"id":51325,"href":"https:\/\/lapost.us\/index.php?rest_route=\/wp\/v2\/posts\/51324\/revisions\/51325"}],"wp:attachment":[{"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=51324"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=51324"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lapost.us\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=51324"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
