CDC recommends collecting and testing a single upper respiratory sample. This sample is then processed. Using a technique called real-time reverse transcriptase (RT)-polymerase chain reaction (PCR), the test can detect the COVID-19 virus RNA genome.

Types of tests. COVID-19 tests are available that can test for current infection or past infection. A viral test tells you if you have a current infection. Two types of viral tests can be used: nucleic acid amplification tests (NAATs) and antigen tests. An antibody test (also known as a serology test) might tell you if you had a past infection. Antibody tests should not be used to diagnose a current infection.

Viral tests are used to look for current infection. A viral test checks specimens from your nose or your mouth to find out if you are currently infected with the virus that causes COVID-19. Viral tests can be performed in a laboratory, at a testing site, or at home or anywhere else. Two types of viral tests are used: nucleic acid amplification ...

In general, a positive antibody test is presumed to mean a person has been infected with SARS-CoV-2, the virus that causes COVID-19, at some point in the past. It does not mean they are currently infected. Antibodies usually start developing within 1 to 3 weeks after infection.

To understand how COVID-19 vaccines work, it helps to first look at how our bodies fight illness. When germs, such as the virus that causes COVID-19, invade our bodies, they attack and multiply. This invasion, called an infection, is what causes illness. Our immune system uses several tools to fight infection.

A positive antibody test result shows you may have antibodies from a previous infection with the virus that causes COVID-19. Antibodies to the virus that causes COVID-19 provide protection from getting infected. CDC is evaluating how long protection from antibodies might last. Cases of reinfection have been reported, but remain rare.

We’ve been asked by readers whether a Covid-19 test can return a positive result if the person tested only has the common cold rather than Covid-19. This is based on the fact that the common cold can be caused by a number of human coronaviruses, which are related to (but not the same as) the new coronavirus which causes Covid-19.

With two negative genetic tests done 24 hours apart, according to CDC, the person is not contagious (shedding virus), meaning the person either has never been infected or (if previously infected) is no longer shedding virus. If immunoglobulin tests are all negative, the test indicates the person has not been recently exposed to the COVID-19 virus.

Note that these recommendations do not apply to people with severe COVID-19 or with weakened immune systems (immunocompromised). I tested positive for COVID-19 but had no symptoms. If you continue to have no symptoms, you can be with others after 10 days have passed since you had a positive viral test for COVID-19.

The CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay, is still a type of PCR test, but rather than individuals having to be tested for Covid-19 and then other respiratory viruses, this test involves taking one sample which can then be simultaneously tested for influenza and SARS-CoV-2.

COVID-19 is caused by infection with a coronavirus first identified in 2019, and flu is caused by infection with influenza viruses. COVID-19 seems to spread more easily than flu. However, as more people become fully vaccinated against COVID-19, the spread of the virus that causes COVID-19 should slow down.

Coronavirus in dogs and cats According to the U.S. Centers for Disease Control and Prevention, a few pets — including cats and dogs — also have been infected with the virus that causes COVID-19.

Evidence collected for SARS-CoV-2 showed that viruses in droplet aerosols (a fine mist) had a half-life of just over an hour but some could survive for three hours or more. Infectious virus could be detected on copper surfaces for up to four hours, on cardboard for up to 24 hours, and on plastic and stainless steel for at least 72 hours.
