New Test for Daratumumab (Darzalex) Patients Helps With M-Protein Accuracy. All myeloma patients are familiar with immunofixation tests (typically abbreviated as IFE, for Immmuno Fixation Electrophoresis), which are tests that looks for the presence of monoclonal cells in the blood (serum).

This abnormal protein is formed within your bone marrow, the soft, blood-producing tissue that fills in the center of most of your bones. Serum protein electrophoresis is an initial test used to identify an M protein and has a key role in quantifying it. An M protein appears as a narrow spike on the agarose gel and should be distinguished from the broad band seen in polyclonal gammopathies associated with cirrhosis and chronic infectious and inflammatory conditions, among others. Protein, total, serum7,28 Normal range: 6.3-7.9 g/dL The level of protein in the blood is measured by a total serum protein test. If the test results show abnormal protein levels, then multiple myeloma, kidney, liver, blood, and other autoimmune diseases may be indicated.

The test examines protein in either urine or the liquid portion of the blood, which medial professionals call the Serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of serum protein. Many subspecialists include serum A total protein blood test can establish any variation in the whole protein composition. In particular, protein blood test tends to establish the levels of two proteins, albumin, and globulin. The two are vital in the body for their functions.

A total protein blood test can establish any variation in the whole protein composition. In particular, protein blood test tends to establish the levels of two proteins, albumin, and globulin. M protein is a virulence factor that can be produced by certain species of Streptococcus. Viruses, parasites and bacteria are covered in protein and sugar molecules that help them gain entry into a host by counteracting the host's defenses. One such molecule is the M protein produced by certain streptococcal bacteria.

A myeloma protein is an abnormal antibody (immunoglobulin) or (more often) a fragment thereof, such as an immunoglobulin light chain, that is produced in excess by an abnormal monoclonal proliferation of plasma cells, typically in multiple myeloma. Other terms for such a protein are M protein, M component, M spike, spike protein, or paraprotein.
