COVID-19 tests are available that can test for current infection or past infection. Human coronaviruses were first identified in the mid-1960s. Types of test.

Tests that detect the presence of the virus that include nucleic acid tests that detect genetic material of the virus and tests that detect specific viral proteins.

There are two main kinds. Molecular tests such as the PCR test which look for the genetic material or RNA thats inside the virus. There are currently two primary types of COVID-19 tests being used to test patients for COVID-19.

The seven coronaviruses that can infect people are. 229E alpha coronavirus NL63 alpha coronavirus. The Johns Hopkins 30-Minute COVID-19 Briefing.
