A negative IgG result coupled with a negative IgM result indicates the absence of prior exposure to mumps virus and nonimmunity. However, a negative result does not rule-out mumps infection or response to vaccination. The specimen may have been collected before the appearance of detectable antibodies.

IgM-/- mice show normal B-cell development and maturation, with IgD replacing membrane-bound and secretory IgM. These data suggest that IgD is largely able to substitute for IgM functions in B-cells. IgD apparently is also able to bind to basophils and mast cells and activate these cells to produce antimicrobial factors that are functional in respiratory immune defence in humans.

It’s a simple blood test and the result is commonly available within a week. Blood Test: Immunoglobulins (IgA, IgG, IgM) What It Is. An immunoglobulin test measures the level of certain immunoglobulins, or antibodies, in the blood. Antibodies are proteins made by the immune system to fight antigens, such as bacteria, viruses, and toxins. The body makes different immunoglobulins to combat different antigens.

There are five major types of antibodies: immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin E (IgE) and immunglobulin D (IgD).

The IgM antibody is one of the five subcategories of antibodies and it is found both in the blood and the lymph. It is the first antibody that is generated by the body while responding to an infection.

The presence of IgG and/or IgM antibody to SARS-CoV-2 indicates that the patient has developed an immune response to the virus. 3,5-8 Although the immune response may protect against reinfection, this has yet to be conclusively established. 16,17 It is not known how long antibodies to the virus will protect someone, if at all.
