Immunofixation electrophoresis (IFE) is a two-stage process using agarose gel electrophoresis with immuno-precipitation. Source: Regenstrief LOINC

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
