As of January 15, 2022, private health insurers are required to reimburse Americans for the at-home COVID-19 rapid antigen tests they purchase. Many Americans are testing themselves for the first time, and some are reporting that their at-home antigen tests are coming back negative despite experiencing symptoms. Here’s what you should know about self-testing when at home.
According to the Centers for Disease Control and Prevention (CDC) antigen tests are less sensitive than polymerase chain reaction (PCR) tests.* At the onset of one’s COVID-19 infection, use of an antigen home test may not indicate a positive result when one is infected with the disease, due to lower sensitivity. Self-tests do not detect antibodies, nor can they measure your level of immunity.
If you suspect that you’ve been infected with COVID-19 due to exposure to a positive individual or you are experiencing symptoms consistent with COVID-19, and you test negative with an at-home rapid antigen home test, you may want to consider taking a PCR test.

Per the CDC’s guidance on self-testing at home, although home antigen tests may not detect the virus, a negative result does not necessarily rule out the possibility of infection. If you’re experiencing COVID-like symptoms, CDC’s COVID-19 Prevention Actions are physical distancing when possible, vaccination, and wearing a high-quality mask around others to prevent transmission of SARS-CoV-2, the respiratory infection that causes COVID-19.
According to the CDC, some self-tests are designed to be used in a series (also known as serial testing). You may want to consider repeating the test 24 to 48 hours later. Multiple negative tests may increase the confidence that you are not infected with the virus that causes COVID-19.
If you suspect that you’ve been infected, exposed to an infected individual, or have symptoms consistent with COVID-19, and test negative with a home test, getting a more accurate and sensitive COVID-19 PCR test could help confirm that the negative results are accurate rather than risk exposing members of your family and others to a possible COVID-19 infection.
