The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
The indirect antiglobulin test, which is used for weak D testing and typing of some red blood cell antigens, detects IgG bound to red blood cells. If IgG is bound to red blood cells in vivo, as may occur in autoimmune hemolytic anemia, hemolytic disease of the newborn and transfusion reactions, [10]: 260 the indirect antiglobulin test will ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

IgG deficiency is a form of dysgammaglobulinemia where the proportional levels of the IgG isotype are reduced relative to other immunoglobulin isotypes.. IgG deficiency is often found in children as transient hypogammaglobulinemia of infancy, which may occur with or without additional decreases in IgA or IgM.
This is a recombinant monoclonal antibody to human IgG. It has the ability to bind to all 4 human IgG subtypes: IgG1, IgG2, IgG3, and IgG4. [7] Anti-Human IgG [8E11] This is a recombinant monoclonal antibody to human IgG. However, it can screen for IgG in nonhuman primates including vervets, chimpanzees, and mangabeys.
An antibody elution removes bound antibody from the surface of a red blood cell to aid in the antibody identification process. An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells, in order to determine the blood group system antigen the antibody targets.

Coombs - after birth, the newborn will have a direct Coombs test run to confirm antibodies attached to the infant's red blood cells. This test is run from cord blood. [5] In some cases, the direct Coombs will be negative but severe, even fatal HDN can occur. [15] An indirect Coombs needs to be run in cases of anti-C, [16] anti-c, [16] or anti-M ...
