HOW DOES THE IgG-IgM COVID-19 ANTIBODIES TESTING WORK?
It’s actually very simple. Our body’s IgM’s are the first line of defense in fighting the virus. If you are positive for IgM, it means you have been exposed to the virus within the past 3-5 days . A positive test means you have the virus and should self quarantine for at least 14 days. An IgG positive test means that you were exposed to the virus 3-4 weeks ago and now have the antibodies to fight the disease.
