What are the different types of tests for COVID 19?

The two kinds of tests are viral tests, also called diagnostic tests, and antibody tests, also called a serology or serological test.

• ‍Viral tests detect the presence of the SARS-CoV-2 virus. A positive result means the person is currently infected.
• ‍Antibody tests detect the presence of antibodies that the body produces after being exposed to the virus. A positive result means the person was infected at some time in the past.
