Using the search box in the EUA tables, you can use keywords to search and filter the type of test or collection kit you are looking for. For additional information on reading and understanding your test results, see Understanding At-Home OTC COVID-19 Antigen Diagnostic Test Results.įor details about each authorized COVID-19 diagnostic test, see the lists of authorized Molecular Diagnostic Tests and Antigen Diagnostic Tests, as well as the At-Home COVID-19 Diagnostic Tests webpage. For more information about how to reduce your risk of getting a false negative result on an at-home COVID-19 antigen test, read our FDA Safety Communication. To increase the accuracy of an at-home COVID-19 antigen diagnostic test, it is important to perform repeat testing, after 48 hours, following a negative test result, whether you have symptoms or not, to reduce your risk of a false negative test result. Be aware that COVID-19 diagnostic tests are authorized for specific uses and that laboratory-based molecular COVID-19 tests, are generally more accurate than at-home tests. Be sure to check the At-Home OTC COVID-19 Diagnostic Tests website for information on expiration dates, who can use the test, and other details that may help you decide what test is right for you.

Samples for COVID-19 diagnostic tests are typically collected using an anterior nares (nasal) swab sample. Antigen tests, often referred to as rapid tests or, for some, at-home or self tests, which detect proteins called antigens from the virus.Molecular tests, such as polymerase chain reaction (PCR) and other nucleic acid amplification tests (NAATs) tests, which detect genetic material called RNA from the virus.There are two common types of COVID-19 diagnostic tests: There are different types of COVID-19 tests – diagnostic tests and antibody tests.ĭiagnostic tests can show if you currently are infected with SARS-CoV-2, the virus that causes COVID-19.
