COVID-19 Testing: What You Need to Know | CDC

Types of COVID-19 Tests

COVID-19 tests can detect either SARS-CoV-2 or biomarkers of SARS-CoV-2, the virus that causes COVID-19, or antibodies that your consistency 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 character of test is called a “ viral ” test because it looks for viral contagion. antigen tests, Nucleic Acid Amplification Tests ( NAATs ) and other tests are viral tests .
Tests for antibodies may tell you if you have had a past infection with the virus that causes COVID-19. Your soundbox creates antibodies after getting infected with SARS-CoV-2 or after getting vaccinated against COVID-19. These tests are called “ antibody ” or “ serology ” tests .
Testing is very authoritative to help reduce the spread of COVID-19. You should constantly discuss your test results with your healthcare provider.

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 tests, some NAATs, and other tests.
    • 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 trial ( besides known as a serology test ) can detect antibodies to SARS-CoV-2 in your blood. Antibodies are proteins that your immune organization makes to help fight contagion and protect you from getting brainsick in the future .
antibody tests should not be used to diagnose a stream infection, but they may indicate if you had a past infection. antibody tests help learn about how human immune systems defend against the virus, american samoa well as memorize about population-level protection. If you get an antibody examination after receiving a vaccine, you might test positive by some ( but not all ) antibody tests. This depends on which type of antibody the specific examination detects .
antibody testing is not presently recommended to determine :

  • If you have a current infection.
  • If you have immunity to SARS-CoV-2 following COVID-19 vaccination.
  • Whether you need to get a booster following COVID-19 vaccination.
  • Whether you need to quarantine after a known or suspected exposure to COVID-19.
