There are 5 classes of immunoglobulin, IgG, A, M, D and E, determined by their heavy chains. In normal serum, approximately 80% is IgG, 15% IgA, 5% IgM, with 0.2% IgD and trace IgE. Laboratory testing for immunoglobulins in peripheral blood typically detects the 3 major classes, IgG, A and M.
19 wrz 2023 · What Do My Results Mean? This test checks the amount of certain antibodies called immunoglobulins in your body. Antibodies are proteins that your immune cells make to fight off bacteria,...
24 paź 2023 · What Do My Immunoglobulin G Test Results Mean? Let’s focus in on IgG. If IgG levels are within the normal range, they are considered healthy. If levels are outside of the normal range, however, some follow-up tests may be needed, including a closer look at some of the sub-classes of IgG.
You have IgA antibodies in your blood, saliva, and gastric "juices." An immunoglobulins blood test measures the amounts of IgM, IgG, and IgA in your blood to help diagnose different types of health conditions that may affect your immune system. Other names: quantitative immunoglobulins, total immunoglobulins, IgG, IgM, IgA testing
Laboratory levels can vary by laboratory due to differences in testing technique. What do the results mean? IgG, IgA, and IgM levels are usually evaluated together. Abnormal test results indicate that there is something affecting the immune system and may suggest the need for further testing.

23 sty 2024 · IgG3 comprises around 5 to 10% of total IgG and has a molecular weight of 170 kDa. They play a major role in the immune responses against protein or polypeptide antigens which are T dependent antigens. The IgG3 are particularly good opsonins and mediators of ADCC because FcγRs bind sIgG3 antibodies with high affinity.
