When should I consider using a self test?
Self-tests may be used if you have COVID-19 symptoms or have been exposed or potentially exposed to an individual with COVID-19.
Even if you don’t have symptoms and have not been exposed to an individual with COVID-19, using a self-test before gathering indoors with others can help you know if you are likely to spread the virus that causes COVID-19. This is especially important before gathering with unvaccinated children or adults, older individuals, those who are immunocompromised, or individuals at risk of severe disease.
My test was positive, what should I do now?
If you are at risk for severe disease from COVID-19 infection, you should contact your healthcare provider immediately to talk about any treatments you may need.
People over age 65 or those with certain medical conditions are more likely to get seriously ill and require hospitalization, especially if they are unvaccinated. Please visit the CDC website to find out if you have any medical conditions that put you at greater risk for severe disease. If you have questions or are unsure about your risk, you should contact your healthcare provider. If you have or develop severe symptoms, such as difficulty breathing, you should call 911.
You will need to stay home and isolate yourself from others for 10 days until you are no longer able to spread the disease to others.
Tell your close contacts that they may have been exposed. You can begin spreading COVID-19 starting 2 days before you have any symptoms or test positive. By telling your close contacts they may have been exposed, you are helping to protect everyone.
My test was negative, what does that mean?
A negative test result means the virus that causes COVID-19 was not found, and you may have a lower risk of spreading the disease to others. If you took the test while you had symptoms and followed all instructions carefully, a negative result means your current illness is probably not COVID-19, though it does not guarantee you do not have a COVID-19 infection.
It is possible for a test to give a negative result in some people who have COVID-19. This is called a false negative. You could also test negative if the specimen was collected too early in your infection. In this case, you could test positive later during your illness.
If you have symptoms of COVID-19, especially if you know you were exposed to someone else with COVID-19 or if COVID-19 is common in your community, consider getting tested at a testing site or repeat testing with a self-test in a day or two.
How often should I repeat my self-test?
Some self-tests are designed to be repeated. Repeated (sometimes called serial) self-testing is when a person tests themselves multiple times for COVID-19, or on a routine basis, such as every few days. By testing more frequently, you might detect the virus that causes COVID-19 more quickly and could reduce the spread of infection. Some self-tests include instructions for performing repeat testing, including the number of days between tests. No matter which test you are taking, please read and follow the instructions carefully.
