What is monoclonal protein in the blood? Best Answer: Monoclonal protein (M-protein) is an antibody found in people with multiple myeloma and other plasma cell tumors. Multiple myeloma: This is a type of cancer that begins in plasma cells (antibody producing white blood cells) Source(s): Optimist · 9 years ago.

What is Multiple Myeloma? Myeloma cells result in the production of abnormal antibodies, or M proteins. A high level of M protein in the blood is the hallmark characteristic of multiple myeloma. Additionally, all myeloma cells are identical to each other and produce large quantities of the same specific M protein (for example, IgG or IgA).

Monoclonal Gammopathies Monoclonal gammopathies are conditions in which abnormal proteins are found in the blood. Click to Enlarge. These proteins develop from a small number of plasma cells in the bone marrow. Plasma cells make up just 1 percent of bone marrow cells.Their main function is to fight off infection. The most common condition linked with these abnormal proteins is monoclonal gammopathy of undetermined significance (MGUS).It is not cancer. But people with MGUS have an increased risk of developing serious diseases of the bone marrow and blood.onoclonal gammopathies are conditions in which abnormal proteins are found in the blood.

Mononucleosis Tests Test Overview. Mononucleosis tests are blood tests to look for antibodies that indicate mononucleosis (mono), which is usually caused by the Epstein-Barr virus (EBV). The antibodies are made by the immune system to fight an infection. Mono tests include: Monospot test (heterophil test).

- MGUS (monoclonal gammopathy of unknown significance) is a condition where the body makes an abnormal protein, called a paraprotein. These paraproteins are found in the blood and urine when they’re tested. MGUS is linked to the immune system. The immune system helps the body fight infection and disease.

Disease and Treatment Multiple Myeloma (also known as Myeloma or Plasma Cell Myeloma) is a malignancy of plasma cells, which are the white blood cells responsible for the production of antibodies (proteins).n myeloma, all the abnormal plasma cells make the same antibody. Therefore the myeloma can be classified by the type of light and heavy chains produced, such as IgG kappa, IgG lambda, IgA kappa, or IgA lambda, etc. The most common type of heavy chain produced in myeloma is IgG, followed by IgA and then IgD.

Polyclonal antibodies Polyclonal antibodies (pAbs) are antibodies that are secreted by different B cell lineages within the body (whereas monoclonal antibodies come from a single cell lineage). They are a collection of immunoglobulin molecules that react against a specific antigen, each identifying a different epitope.

- The main reason is that production of a single, monoclonal protein (M-protein) is a characteristic feature of multiple myeloma. The test used to measure the amount of monoclonal protein in the blood or urine is protein electrophoresis.This M-protein is manufactured (synthesized) by malignant plasma cells (or myeloma.2 13 Figure 2.

What Is the Significance of Monoclonal Gammopathy of Undetermined Significance (MGUS)? The patient is found to have a monoclonal protein (M protein) of 12 g/L, IgG type, and normal free light chain ratio. All other lab results including hemoglobin, creatinine, and calcium are within their normal ranges. A skeletal survey is done which is negative for lytic lesions. A bone marrow biopsy is also performed which reveals <10% plasma cells. The patient is referred to a hematologist who informs him that he has monoclonal gammopathy of undetermined significance (MGUS).

Final Diagnosis -- Plasma cell neoplasm â kappa light chain restricted The prior biopsy report, available on next follow-up, revealed a diagnosis of plasma cell neoplasm of the chest wall. A laboratory workup for multiple myeloma revealed a M-spike on serum protein electrophoresis (SPEP) which was confirmed on immunofixation studies to be a IgA Kappa monoclonal protein.he kappa:lambda ratio was also markedly increased to 13.1. Other significant laboratory results included Hemoglobin of 11.9 g/dl, total WBC count of 5700/mm3 with no evidence of plasma cells in the peripheral blood, slightly elevated serum calcium (11 mg/dl), and creatinine of 1.1 mg/dl.
