What molecular tests are available for home use? As of this writing the test was in stock at Walmart.Īccuracy: In a clinical study of symptomatic patients, the InteliSwab test correctly identified 84 percent of the positive cases and 98 percent of negative cases, compared to PCR, according to data submitted to the FDA. Where to purchase: Walgreens and Walmart. InteliSwab COVID-19 Rapid Antigen Home Test As of this writing they were in stock at CVS, Sam’s Club, Walgreens, and Walmart.Īccuracy: The test correctly gave a positive result 84.6 percent of the time, compared to a PCR test, and correctly gave a negative result 98.5 percent of the time, according to data submitted to the FDA. Sold at: Abbott’s website sells the tests directly, and they are sold online at CVS, Walmart, Rite Aid, Sam’s Club, and Walgreens. The figures give a general sense of each test’s performance but should not be interpreted as a head-to-head comparison of the various brands. The figures reflect the findings of tests that were performed on varying numbers of subjects, some symptomatic and some asymptomatic, at different points during the pandemic. Note that “accuracy” refers to data the manufacturers submitted in applications to the FDA. These are the brands that are currently available from major U.S. The FDA has approved 13 fully at-home COVID antigen tests.

The CDC explains: “Performing serial tests, meaning two or more tests over several days with at least 24 hours between tests-with one test as close as possible to the event you will attend-improves the reliability of testing and reduces your risk of transmitting disease to others even further.” Certain manufacturers recommend serial testing to boost accuracy, which is why some kits come with two tests. What antigen tests are available for home use?Īntigen tests are more sensitive in people experiencing symptoms, and within the first week that symptoms emerge, as that’s when people have the highest viral load. But when people lament the lack of at-home testing, they’re usually talking about rapid antigen tests that allow users to swab themselves and get a result in as little as 15 minutes, without any lab processing and without a prescription. At-home collection kits – which allow people to collect their own sample at home, mail their results to a lab, and get results within days – are available for each type of test. The FDA has issued emergency-use authorization for a variety of COVID-19 tests. These tests are not used for diagnosing an active infection. Antibody tests, which are blood tests that determine if the body has had an immune response to the virus.There are a handful of tests in the former two categories that can be performed at home, providing users with results in a matter of hours or minutes, as opposed to days with PCR. The category also includes loop-mediated isothermal amplification (LAMP) tests, and clustered, regularly interspaced short palindromic repeat (CRISPR) tests. The most familiar test from this category is the polymerase chain reaction (or PCR) test, which requires lab processing. These are considered the “gold standard” for diagnosing COVID, as they are generally more accurate than antigen tests. Molecular tests, which test for an active infection by amplifying genetic material from the virus.Most at-home tests and “rapid tests” performed by healthcare providers fall in this category. Antigen tests, which test for an active infection by detecting specific virus proteins.So why are home COVID tests, which are cheap and widely available in other countries, still so hard to find in the U.S.? Can they detect the Omicron variant? Where can you buy a home test and what are your options? And when, if ever, will we Americans know the joy of jabbing a swab up their nose whenever they please? Here’s what you need to know.
#TARGET BINAX NOW FREE#
Though Americans can now order four free home COVID tests from the government (as well as free N95 masks), rapid antigen tests are often out of stock online and in stores. In late December, holiday plans and the emergence of the Omicron variant strained America’s COVID testing capabilities in general, and demand for home tests skyrocketed. As the Post reported, the White House was finally trying to make that a reality, awarding a nearly $232 million contract to help Ellume scale up production.īut nearly a year later, at-home COVID tests are still scarce. On Februthe Washington Post published a story titled, “A fast, at-home coronavirus test will be available to Americans this year.” At the time, public-health officials had been calling for home COVID-19 tests for months, saying that allowing people to determine whether they’re infected without lining up at a clinic or waiting days for lab results could help turn the tide in the pandemic.
