COVID-19 Testing worldwide health and medical information

How to Get a COVID-19 Test

Low or no-cost COVID-19 tests are available to everyone in the U.S., including the uninsured, at health centers and select pharmacies nationwide. Additional testing sites may be available in your area. Contact your health care provider or your state or local public health department for more information. Testing is very important to help reduce the spread of COVID-19. You should always discuss your test results with your healthcare provider.

What is diagnostic data?

In general, diagnostic data refers to information collected and used in the investigation and diagnosis of a disease. For the COVID-19 pandemic, U.S. diagnostic data refers to information collected from laboratory and non-laboratory diagnostic testing for the purposes of clinical diagnosis and public health screening.

Reasons to Get Tested

Types of COVID-19 Tests

COVID-19 tests can detect either SARS-CoV-2, the virus that causes COVID-19, or antibodies that your body makes after getting COVID-19 or after getting vaccinated.

Tests for SARS-CoV-2 tell you if you have an infection at the time of the test. This type of test is called a "viral" test because it looks for viral infection. Antigen or Nucleic Acid Amplification Tests (NAATs) are viral tests.

Tests for antibodies may tell you if you have had a past infection with the virus that causes COVID-19. Your body creates antibodies after getting infected with SARS-CoV-2 or after getting vaccinated against COVID-19. These tests are called "antibody" or "serology" tests.

Viral Tests

A viral test tells you if you are infected with SARS-CoV-2, the virus that causes COVID-19, using samples that come from your nose or mouth. There are two types of viral tests: rapid tests and laboratory tests. COVID-19 testing is one of many risk-reduction measures, along with vaccination, masking, and physical distancing, that protect you and others by reducing the chances of spreading COVID-19. Rapid Point-of-Care tests, test performed or interpreted by someone other than the individual being tested, can be performed in minutes and can include antigen and some NAATs. Self-tests are rapid tests that can be taken at home or anywhere, are easy to use, and produce rapid results. Laboratory tests can take days to complete and include RT-PCR and other types of NAATs.

Antibody Tests

An antibody test (also known as a serology test) can detect antibodies to SARS-CoV-2 in your blood. Antibodies are proteins that your immune system makes to help fight infection and protect you from getting sick in the future. Antibody tests should not be used to diagnose a current infection, but they may indicate if you had a past infection. Antibody tests help learn about how human immune systems defend against the virus, as well as learn about population-level protection. If you get an antibody test after receiving a vaccine, you might test positive by some (but not all) antibody tests. This depends on which type of antibody the specific test detects.

Tests are available for every residential address in the U.S., including Alaska, Hawaii, Puerto Rico, U.S. Territories, and overseas military and diplomatic addresses.

Can I choose what type or brand of test I get?

All tests distributed as part of this program are FDA-authorized at-home rapid antigen tests. You will not be able to choose the brand you order as part of this program.

When will I get my tests and how will they be delivered?

Tests will be delivered in the mail through the U.S. Postal Service and will typically ship within 7-12 days of ordering. All orders within the continental United States will be sent through First Class Package Service. Shipments to Alaska, Hawaii, U.S. Territories, and overseas military and diplomatic addresses will be sent through Priority Mail.

Health Centers

Health centers are an important component of the national response to the COVID-19 pandemic. Find a health center near you, for available COVID-19 screening and testing. Please call the health center for more information about availability of low or no-cost testing. Health centers provide COVID-19 testing services to individuals who meet criteria for COVID-19 testing, regardless of their ability to pay. Health centers will determine whether there is available reimbursement, funding, or compensation sources, and any related cost sharing restrictions for COVID-19 testing prior to billing patients. If there are any out-of-pocket costs—for example, in the case of no or only partial coverage by private insurance—health centers will provide sliding fee discounts for eligible patients based on income and family size.
