At Nourishing Medicine, LLC we want to help ensure you are well. We are now offering COVID 19 antibody testing to determine if you have had prior exposure and potential immunity to the Coronavirus. It should be noted that we currently do not know how long immunity to the virus lasts.
When you are exposed to a virus or bacteria your body makes antibodies (proteins) in response to it in order to fight off the infection. In the case of the Coronavirus, your body sees the virus as a foreign substance and makes proteins to fight the infection. By doing a blood test we can see if these antibodies are present and thus get an idea of your prior exposure or immunity.
IgM and IgG are the two types of antibodies tested. IgM antibodies are produced within days of exposure to a foreign substance and circulate for about 2-3 weeks in the body. IgG antibodies are produced approximately 3-4 weeks after the start of an infection. These are the antibodies that produce “memory” of past infection and help prevent future illness from the same infection.
It is a simple blood test done in our Naperville and Waterman offices with results in as little as 2 days.
No. The antibody test is best for people who are not currently sick or have been sick in the past 3-4 weeks and are wondering if the illness was due to Coronavirus.

A positive IgG antibody test does not guarantee protection from coronavirus. We are uncertain at what level of IgG and for how long antibodies can be protective. For those reasons, it’s still best practice to follow the usual precautions to help stop the spread of the virus. Also unknown is whether patients can be re-infected with the virus after a period of time. If you start to develop symptoms of COVID-19 like fever, cough, chest tightness, and shortness of breath, do not assume that a positive antibody test means you cannot have the infection.
