There are two kinds of tests for viruses like COVID-19. One tests for the presence of the virus in the sample, and the other for antibodies to the virus. Both are important for understanding who is infected and might transmit the virus to others, who have had the virus and might now be immune, and even who might potentially help others with treatment.
COVID-19 IgG antibody testing, also known as serology testing, checks for a type of antibody called immunoglobulin G (IgG). If you have been exposed to the virus that causes COVID-19, your body typically produces IgG antibodies as part of the immune response to the virus. Antibody tests may not be able to show if you have been exposed to COVID-19 because it can take at least two weeks after exposure to develop antibodies.
This type of COVID-19 test is for individuals who think they may have had COVID-19 and do not currently have symptoms. This test does not tell you if you have an active infection. Please consult your healthcare provider if you have symptoms or suspect you currently have COVID-19.
