Serum protein electrophoresis showing a paraprotein (spike/peak in the gamma zone) in a patient with multiple myeloma.. 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 or Monoclonal gammopathy of ...
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
For most substances presented, the optimal levels are the ones normally found in the population as well. More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give ...
The globulin level may be normal in established disease. A doctor may request protein electrophoresis of the blood and urine, which might show the presence of a paraprotein (monoclonal protein, or M protein) band, with or without reduction of the other
Blood plasma protein 3.5-5.0 × 10 −2 [1] Aluminum: 1-40 × 10 −8: 1-88 × 10 −8: Selenium : 60–150 ng/mL Aldosterone: Regulates electrolyte balance supine 3-10 × 10 −11: standing, male 6-22 × 10 −11: standing, female 5-30 × 10 −11: Amino acids: Protein building blocks total 3.8-5.3 × 10 −4: nitrogen 4.6-6.8 × 10 −5: 3.0 ...
Viral matrix protein, structural protein linking the viral envelope with the virus capsid; Coronavirus membrane protein, structural protein expressed from the M gene in coronaviruses; Myeloma protein, also called paraprotein, an abnormal protein in the urine or blood, often seen in multiple myeloma or monoclonal gammopathy of undetermined ...
In a more recent study, MGUS patients that had the presence of none, 1, 2, or 3 of the three following risk factors, serum M protein levels >15 gram/liter, a non-IgG isotype, and abnormal free light chain ratios, had 5, 32, 37, and 58% chances, respectively, of progressing to multiple myeloma within 20 years.
Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates. IgM is the first antibody to appear in the response to initial exposure to an antigen ; [ 1 ] [ 2 ] causing it to also be called an acute phase antibody.
