I have sarciodosis
what does it mean when my IGM is low at 28L
also called gamma globulin electrophoresis, or immunoglobulin electrophoresis, is a method of determining the blood levels of three major immunoglobulins: immunoglobulin M (IgM), immunoglobulin G (IgG), and immunoglobulin A (IgA).
Immunoglobulin G; it makes up 80% of the Immunoglobulin content in the bloodstream
There are five immunoglobulin classes (isotypes) of antibody molecules found in serum: IgG, IgM, IgA, IgE, and IgD. IgA (immunoglobulin A) IgD (immunoglobulin D) IgE (immunoglobulin E) IgG (immunoglobulin G) IgM (immunoglobulin M)
The answer is IgG
Normal range is between 700 and 1600.
The class of immunoglobulin to respond to the fist exposure of an antigen is immunoglobulin class M (IgM). While Immunoglobulin G (IgG) would predominate on the second exposure.
The immunoglobulin G (IgG) is the most important for humans; see also the link below.
what is immunoglobulin for
The class of immunoglobulin that is produced in the primary immune response is Immmunoglobulin M (IgM). On secondary exposure, the class that predominates would be Immunoglobulin G (IgG).
IgG is an immunoglobluin monomer, meaning that it is one immunoglobulin that is small enough to cross the placenta. An example would be the Rh antibody that causes isoimmunization between Rh negative mothers and Rh positive fetuses. In constrast, ABO blood group immunoglobulins are IgM which is a pentamer, meaning it is composed of 5 immunoglobulins and is too large to cross the placenta.
