Antibody testing determines the presence of antibodies that recognize markers of SARS-CoV-2, the virus that causes COVID-19, indicating that the body previously had been infected.

See the glossary section of our website to learn about the difference between Nucleocapsid Protein Antibody Tests and Spike Protein Antibody Tests.

PCR testing is used to accurately detect active infections. It is a type of molecular test and considered the gold standard for testing. PCR is the most commonly used nucleic acid amplification test (NAAT).

Antigen testing is used to identify active infections. It expands testing capacity as a fast, reliable, and affordable screening and diagnostic option.
