Be aware the FDA expects similar performance with Point of Care (POC) COVID-19 antigen tests performed at a clinic or doctor's office.Visit At-Home OTC COVID-19 Diagnostic Tests for a list of all FDA-authorized home tests and for more information about who can use a test and for what ages. You do not need to use the same brand of test each time for repeat testing. If you plan to use at-home COVID-19 antigen tests, have several tests on hand so you can test more than once.This is the reason why repeat testing is important. COVID-19 antigen tests may not detect the SARS-CoV-2 virus early in an infection, meaning testing soon after you were exposed to someone with COVID-19 could lead to a false-negative result, especially if you don't have symptoms. Be aware that at-home COVID-19 antigen tests are less accurate than molecular tests.Recommendations: Before you use a COVID-19 antigen test: At-home COVID-19 antigen tests, while not perfect, provide a fast and convenient COVID-19 testing option. ![]() COVID-19 diagnostic testing remains a cornerstone of our nation's fight against COVID-19. Today's recommendations are based on the latest study results from people with likely omicron infection showing that repeat testing after a negative at-home COVID-19 antigen test result increases the chance of an accurate result. Over the course of the COVID-19 pandemic, public health scientists have continued to learn about the SARS-CoV-2 virus and the impact of variants on diagnostic tests that detect SARS-CoV-2. Today, the FDA is highlighting the continued need for repeat, or serial testing when people get a negative result with an at-home COVID-19 antigen test, including recommending additional testing over a longer period of time. 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't have COVID-19 symptoms. ![]() Currently, all at-home COVID-19 antigen tests are FDA-authorized for repeat, or serial use. This is especially true early in an infection or in people who do not have COVID-19 symptoms. At-home COVID-19 antigen tests are less likely to detect the SARS-CoV-2 virus than molecular tests, such as polymerase chain reaction (PCR) tests. The FDA recommends repeat testing following a negative result whether or not you have COVID-19 symptoms.Īt-home COVID-19 antigen tests detect proteins, called antigens, from the SARS-CoV-2, the virus that causes COVID-19. Food and Drug Administration (FDA) is advising people to perform repeat, or serial, testing following a negative result on any at-home COVID-19 antigen test, to reduce the risk an infection may be missed (false negative result) and to help prevent people from unknowingly spreading the SARS-CoV-2 virus to others. You should, however, still follow CDC guidelines around travel to and from the US.Perform repeat, or serial testing following a negative result on any at-home COVID-19 test, whether or not you have symptoms. by air, land or sea from a foreign country, you will no longer need to show a negative COVID-19 test result or proof of recovery in the last 90 days. Traveling without COVID testing requirement Previously, the viral test could be taken within three days of departure. In December 2021, as the omicron variant spread rapidly around the world, the CDC amended its order to require a negative COVID-19 viral test result taken no more than one day before travel. ![]() The requirement applies to all passengers, regardless of citizenship or vaccination status, according to the CDC website. Since January 2021, the CDC has required all air passengers over the age of 2 to show proof of a negative COVID-19 viral test or documentation of recovery within the last 90 days before boarding a flight from a foreign country into the United States. “If there is a need to reinstate a pre-departure testing requirement - including due to a new, concerning variant - CDC will not hesitate to act." COVID-19 testing requirement in place since 2021 The CDC will reevaluate its decision in 90 days - and after that on an ongoing basis - to determine if the requirement needs to be reinstated, a Biden administration official told CNBC.
