What does low total immunoglobulin g levels mean?

See an immunologist: Immunoglobulin g (igg) is the main type of antibody found in the blood and is used by your body to help fight off infections.

Can you tell me physically and structurally what is the difference between immunoglobulin g and m etc.?

Can you tell me physically and structurally what is the difference between immunoglobulin g and m etc.?

Simply Put: Both IgG and IgM are immunoglobulin proteins with a roughly "Y" shape which binds to an antigen (foreign substance in the body) at one end and a cellular receptor at the other end. The principal differences lie in how and when they form. IgM is made early in infections and form pentamers. IgG is made later in infections, is more specific, and circulates as monomers. ...Read more

What does low immunoglobulin g subclass 2 on blood work mean?

Low gamma globulin: By itself, a slightly low level of one igg subclass is a very nonspecific finding. A very low level would be worrisome, but really, what is needed is to look at this information in the context of vaccine responses to Pneumovax vaccine. If the functional antibodies made by the immune system are at normal levels, the gross levels of antibody are less worrisome. ...Read more

immunoglobulin a 90 means
?

Immunoglobulins: Ige is the allergic antibody (this was normal). An elevated igg level might simply be if he was fighting an active infection at the time (this is a good sign). Iga protects mucosal membranes (sinus, lungs, GI tract, urinary tract) and his level is normal. Feel reassured that these labs look very good. ...Read more
