“And the reason for that is because the gold standard PCR test is run on the sample, and the people running the test are professionals.” FDA-authorized home collection kitsīelow are some of the most widely available Covid home collection tests on the FDA-authorized list. “These home collection kits have better accuracy than home testing kits,” Garner said. When the lab receives the sample, experts run tests on it and you receive your results a few days later. While there are no approved PCR tests for at-home testing, you can collect the sample for a PCR test at home and mail that sample to a lab. From there, the methods differ, and experts said those differences determine how reliable tests are and how you should use them. The two testing methods are similar in that they can diagnose infection, and are performed on either nose or throat swabs. Each one detects different parts of the Covid virus. The most well-known type of molecular test is the PCR test. Home collection and test kits fall into two buckets on the FDA’s lists: molecular diagnostic tests and antigen diagnostic tests.

Here’s how to start. “But if you’re feeling fine, you may need to be tested much more frequently than just today to say you can go on that trip next week.” Related “If you’re symptomatic and you’re testing because you don’t want to go to work sick, at-home tests are going to be very helpful,” she said. So are at-home testing methods reliable? The answer is complicated and often comes down to who is being tested, when the test takes place and what type of test is being used, explained Sharon Nachman, MD, chief of the division chief of pediatric infectious diseases at Stony Brook Children’s Hospital. At-home testing kits do not require you to send the sample to a lab for testing. At-home collection kits prompt you to collect a sample and mail that sample to a lab - the lab performs a PCR test and then you get your results a day or two later. Home collection tests generally produce more accurate results than at-home testing kits. If you test too early, there may only be low levels of the virus present in the sample, which could lead to an inaccurate result.

At-home testing kits are not as accurate as PCR tests done in professional labs because at-home testing - sometimes referred to as “rapid tests” - require a higher amount of virus in a sample in order to detect a positive result. No PCR test is approved for at-home testing, meaning “the most accurate Covid test cannot be done entirely at home,” he said. The best type of diagnostic Covid test is the Polymerase Chain Reaction (PCR) test, according to Omai Garner, PhD, chief of clinical microbiology for UCLA Health. “If you had a high risk exposure and/or are symptomatic and you have a negative test, it still may be worthwhile to get a formal test done in a hospital lab.” How accurate are at-home Covid test kits? “These tests need to be used judiciously,” Beeler said. But there’s danger in deriving a false sense of security from at-home testing methods as they’re generally less sensitive than tests performed by professionals in medical offices. The benefit of at-home Covid testing methods is that they allow people to get tested more frequently, which could lead to catching more infections and, in turn, decrease spread, noted Cole Beeler, MD, director of symptomatic testing for Indiana University’s COVID-19 Medical Response Team and an assistant professor at the IU School of Medicine.
