Immunoglobulin M (IgM):
Fasting Required: No
Lab: Quest Diagnostics
Specimen: Blood
Results: Average processing time, Set up: Tues-Sat; Report available: 5 days
Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Description: IgM is a type of antibody, a protein produced by the immune system to fight infections. It is the first antibody to be produced in response to an initial exposure to an antigen (a foreign substance that triggers an immune response).
Increased IgM is associated with Waldenström's macroglobulinemia, infectious mononucleosis, viral infections, nephrotic syndrome, and estrogen therapy; decreased IgM is found in selective IgM deficiency, Bruton's Disease, and acquired immune deficiency.
