IgM is produced upon initial exposure to an antigen. For example, when a person receives the first tetanus vaccination, antitetanus antibodies of the IgM class are produced 10 to 14 days later. IgM is abundant in the blood.

The largest antibody produced by the fetus is Immunoglobulin M (IgM). It is the first antibody to be produced in response to an infection and plays a crucial role in the fetal immune response. IgM is typically produced by the fetus around the 20th week of gestation and is important for detecting and neutralizing pathogens. Unlike other antibody classes, IgM is pentameric in structure, allowing it to effectively bind to multiple antigens.
IgM is the type of antibody that is made early in infections. If you have it then that means you recently had an infection with what ever is being tested, in this case, toxoplasma.
The results for susceptibility are: antibody to EA = negative, antibody to VCA (either IgM or IgG) = negative, antibody to EBNA = negative.
Ig A
IgM is the class of antibody first secreted in response to a new antigen. It is produced during the initial immune response and helps to activate other components of the immune system.
The results for current or recent infection are: antibody to EA = positive, antibody to VCA IgM = positive, antibody to VCA IgG = positive, antibody to EBNA = negative.
Repeated freeze/thaw cycles can denature an antibody, causing it to form aggregates that reduce the antibody's binding capacity.
Toxoplasma is commonly known as Toxoplasma gondii. It is obligate intercellular parasite that can infect the widest range of hosts known to science. Ab is an abbreviation for "antibody" of which IgM is one. The full name for IgM is Immunoglobulin M. http://en.wikipedia.org/wiki/Immunoglobulin_M
