96420-5Daratumumab [Presence] in Serum by ImmunofixationActive

Term Description

Daratumumab is a monoclonal antibody used to treat multiple myeloma, which is, itself, a disease that results in antibody overproduction, shown as M protein band in immunoelectrophoresis. Daratumumab, the treatment, can show up as part of the M spike and interfere with the assay for the M-protein in multiple myeloma. An antibody against Daratumumab can be added to the assay, which shifts the Daratumumab band, allowing the Daratumumab band to be distinguished from the M-protein band and reported separately.

Part Descriptions

LP420302-4   Daratumumab
Daratumumab is a biologic drug used to treat multiple myeloma. It is a IgG1k human monoclonal antibody directed against CD38, a molecule present on myeloma cells. By binding to CD38, it inhibits the growth of CD38 expressing tumor cells and causes cell death by immune mediated tumor cell lysis [PMID:29915586]. Source: Regenstrief LOINC

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 http://creativecommons.org/licenses/by-sa/3.0/ for details. Source: Wikipedia, Immunofixation
