Part Descriptions

LP14674-3   IgM
Immunoglobulin M ( IgM) is a glycoprotein that consists of five disulfide-linked structural units (a pentamer) held together by a J chain. On the surface of B lymphocytes, however, IgM is found as a monomer and does not express the J chain. IgM is the first immunoglubulin to be made by a fetus and during an immune response, it is the first immunoglobulin to be detected followed by IgG. IgM is the primary antibody against A and B antigens on red blood cells. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See for details.

LP6336-4   Immunofixation
Plasma or concentrated urine is deposited on a gel. With an electrical current the proteins are sorted in function of their size, after which antigens for each targeted type of immunoglobulin are deposited on the gel. Thus more or less narrow bands appear on the gel, marking the location of the various immunoglobulines.
Immunofixation tends to replace protein electrophoresis because:

• it is faster (results within three hours);
• it is somewhat more sensitive. Immunofixation may reveal an immunoglobulin missed out by protein electrophoresis, especially at low concentrations (less than 1 gram/litre);
• it can be partially automated and can be used in more laboratories;
• it is more easily read and interpreted.

Immunofixation is however only sensitive to immunoglobulins and is more expensive than protein electrophoresis. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See for details. Source: Wikipedia, Immunofixation

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
