Background
IgM (immunoglobulin M) is the is the third most abundant and largest antibody in the human circulatory system. IgM is expressed on the surface of immature and mature B cells as a monomer and is expressed in a secreted form as a pentamer with very high avidity. IgM is the first human immunoglobulin to appear in response to initial exposure to an antigen and eliminates pathogens in the early stages of B cell-mediated (humoral) immunity before there is sufficient IgG. IgM is a strong complement activator and agglutinator due to its pentameric structure and binds fragment crystallization (Fc) receptors. IgM has a molecular mass of approximately 970 kDa in its pentamer form with ten binding sites. Typically, however, IgM cannot bind 10 antigens at the same time because the large size of most antigens hampers binding to neighboring sites. IgM antibodies do not pass across the human placenta. IgM antibodies are very useful in the diagnosis of infectious diseases. The presence of IgM antibodies in a patient’s serum indicates recent infection, or in a neonate’s serum specifies an intrauterine infection (e.g. congenital rubella).

Shipping & Handling
No test method can provide total assurance that the hepatitis B virus, hepatitis C virus, human immunodeficiency virus, or any other infectious agents are absent. Thus, all blood products, including purified proteins derived from human blood sources, should be handled at Biosafety Level 2 as recommended by the CDC\NIH manual entitled Biosafety in Microbiological and Biomedical Laboratories for potentially infectious human serum, blood specimens or proteins derived from same. Source material for the human blood product supplied to your facility has been tested for the detection of HIV antibody, Hepatitis B surface antigen, antibody to Hepatitis C, HIV 1 antigen(s), antibody to HTLV - I/II, and syphilis by FDA guidelines. All units were found to be non-reactive/negative for these tests.
