Covid IgG IgM positive means that a person has had a previous infection of the SARS-CoV-2 (the virus that causes Covid-19) and has now developed antibodies to it. The IgG antibody, which stands for immunoglobulin G, is the long-lasting or “memory” antibody that is produced after a person has been exposed to a virus. IgM antibodies, which stand for immunoglobulin M, are the short-term antibodies that are produced in response to an infection.
If a person is tested for Covid IgG IgM antibodies, this means that they are being tested for both types of antibodies. The presence of both antibodies in the blood indicates that the person has had a previous infection and has developed an immune response. It is possible for a person to test positive for both IgG and IgM antibodies, even after they have recovered from the infection. This is because it takes time for the body to develop an immune response and the antibodies may not be detected until the body has fully recovered from the infection.
It is important to note that a positive result for Covid IgG IgM antibodies does not mean that the person is currently infected. It only indicates that the person has had a previous infection and has developed an immune response. It is also important to remember that even if a person tests positive for both IgG and IgM antibodies, they may still be able to spread the virus to others if they are not taking proper precautions. Therefore, it is important to continue to practice social distancing, wear face masks, and wash hands regularly to prevent the spread of the virus.
