This is the key difference between IgM and IgG. Following are the key differences between IgM and IgG: Though both the antibodies (IgM and IgG) are proteins, made for fighting against antigens or foreign particle, IgM The molecular weight of IgM is 900,000MW or 900kDa and that of IgG is 150,000MW or 150kDa. IgM account only 10% of the total IgM is a short term response while IgG is a long term response antibody. For example, imagine that some kid is exposed to chickenpox antigen. His blood IgM value will rise during the time immediately following the exposure.

IgM vs IgG. IgG and IgM are measured together usually to understand the functioning of immune system better. To understand the difference between both, let us first see them individually and get an idea of what they’re and how they work. What is IgM? IgM antibodies are produced by the body immediately after the exposure to the specific antigen. Key Differences Between IgM and IgG. Following are the key differences between IgM and IgG: Though both the antibodies (IgM and IgG) are proteins, made for fighting against antigens or foreign particle, IgM provides immediate response when any antigen enters the body while IgG responds later with the permanent eradication of antigen and its effect is lasting. Immunoglobulin G (IgG), the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections. Immunoglobulin M (IgM) , which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection. IgA and IgM are early indicators of viral exposure and can aid in the diagnosis of COVID-19.
