COVID-19 IgM & IgG Antibody Testing
Upon infection with the SARS-CoV-2 Virus (COVID-19), the body’s immune system tries to fight the virus by producing blood-circulating proteins called antibodies (Ab), also known as an immunoglobulins (Ig). IgM is a type of antibody that appears early after the initial exposure to the virus (antigen or Ag). IgM antibodies can appear as early as 3-5 days after exposure. IgG is another type of antibody that appears later and gradually replaces the IgM antibodies. IgG antibodies generally appear within 3-4 weeks after initial exposure to the virus. The presence of SARS-CoV-2 specific IgM and/or IgG antibodies in a blood sample is a strong indication that an individual has been infected with the SARS-CoV-2 virus.
What will the antibody test tell you?
The COVID-19 antibody test result will allow you the know if you have been exposed/infected with the virus, even if you never showed symptoms, and whether you have acquired antibodies which may help you fight the virus in the future.
This chart describes what happens to the immune system when exposed to the COVID-19 virus. The immune system responds the same way against any infection. First, you are exposed to the virus, which is represented by the blue line. Your body starts making more viruses and then eventually is detected by your white blood cells (WBCs). The WBCs start making antibodies. First they make IgM antibodies to help in the short term, and then they go away. This gives the body time to make the IgG antibodies, which is the same thing as the IgM antibodies, except that the IgG antibodies are for the long term. When you get a vaccine, you go through the same process and end up making IgG antibodies to protect you for the long term.
