If your test results came back negative, please continue to protect yourself and others as per CDC recommendations.




My Antibodies Test results came back positive, now what?

What does my COVID-19 antibody test results tell me?


Negative Result: no novel coronavirus antibody has been detected and the result is negative.
Positive Result, IgM only: the novel coronavirus IgM antibody has been detected and the result is positive for the IgM antibody.
Positive Result, IgG only: the novel coronavirus IgG antibody has been detected and the result is positive for the IgG antibody.
Positive Result, IgG and IgM: the novel coronavirus IgG and IgM antibodies have been detected and the result is positive for both the IgG and IgM antibodies.




My COVID-19 antibody test came back positive for IgG or IgM, or both. What does that mean?


The test is capable of detecting both early marker and late marker, IgM/IgG antibodies in human blood, serum, and plasma samples. While nucleic acid PCR test is only positive during the brief window of acute infection, after which it becomes negative, the Elisa test administered by Xera Med Research is able to detect COVID-19 antibodies for a prolonged period of time after disease resolution, which enables identification of prior infection. Knowledge of prior infection is epidemiologically important and represents a significant unmet need in the management of the COVID-19 pandemic.




What does it mean if I tested positive for IgM antibodies?


IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been infected and that your immune system has started responding to the virus. When IgM is detected you may still be infected, or you may have recently recovered from a COVID-19 infection.




What does it mean if I tested positive for IgG antibodies?


IgG antibodies develop in most patients within seven to 10 days after symptoms of COVID-19 begin. IgG antibodies remain in the blood after an infection has passed. These antibodies indicate that you may have had COVID-19 in the recent past and have developed antibodies that may protect you from future infection. It is unknown at this point how much protection antibodies might provide against reinfection.
