Immunoglobulin G Test
I had an immunoglobulin g, qn, serum appear on my blood test result of 2364, yet my doctor said it's not an issue. Is he right?
Correct.: Look at the person. Look at the numbers only when they shed light on the person. ...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
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. Some people may have a slightly low igg but be perfectly healthy. In others, it may indicate a problem with the immune system that can put one at risk for getting infections. An immunologist can perform additional tests to determine the cause of the low igg. ...Read moreSee 1 more doctor answer
Dont worry but first: thing I would be wondering is why did you have those tests done? Are you having recurrent infections?(not just "regular colds"?),,,but if you were my pt.first thing I would do is repeat the tests to confirm results..If you are having recurrent sinus infections, bronchitis, etc & the repeat tests are similar, next step would be see an allergist/immunologist to further evaluate. Good luck ...Read moreSee 1 more doctor answer
Hard to know: Without more information, it is difficult to know if the levels are low due to lack of production (primary immune deficiency syndrome, medication side effect) or loss of antibodies (protein losing gastrointestinal disease). Also, most people will do well with these levels, but it would be important to know if you have had any recent, or a long history of recurrent, infections. ...Read more
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
Don't worry: I presume that these tests were done because of recurrent sinus or lung infections. Ig g is a measurement of the major antibody type which is involved in fighting against infections. If the total is normal but the igg3 is low, it has little meaning. But if your total igg1 is low, then this may be of concern. ...Read more
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
