MGUS may lead to a more serious condition so checkups are needed throughout your life to find problems as early as possible. Immune Thrombocytopenia Purpura (ITP): What helps? However, a small number of people with MGUS will develop serious cancers or conditions of the blood, such as multiple myeloma. In most cases, Mayo Clinic doesn't require a physician referral. 19952023 Mayo Foundation for Medical Education and Research. Another test, called immunofixation or immunoelectrophoresis, is used to determine the exact type of abnormal antibody (IgG. Immunofixation electrophoresis (IFE) is performed to identify the immunoglobulin heavy chain and/or light chain. An absent alpha-1 fraction is consistent with A1AT deficiency disease and should be followed by a quantitative A1AT assay (AAT / Alpha-1-Antitrypsin, Serum). Protein Electrophoreses are within range, Hi Dr. David,This is the guy who was consulting with you previously about monoclonal diseases like myeloma and amyloidosis. If a monoclonal protein is identified, its immunoglobulin class (IgG, IgA, IgM, IgD, IgE) and light chain type (kappa, lambda) are determined by immunofixation.

Bence-Jones proteins are 1 type. Importantly, the addition of the serum FLC assay to serum PEL and IFE makes the serum diagnostic studies sufficiently sensitive so that urine specimens are no longer required as part of initial diagnostic studies. Several types of proteins are present in all tissue throughout the body, including the blood. The proteins are visualized by staining with amido black and the intensity of staining is quantitated by densitometry (Sebia HYDRASYS 2 Scan). The precise cause of MGUS isn't known.

Multiple Myeloma (also known as myeloma) is cancer of the plasma cells in the bone marrow. WebIn some cases, myeloma isn't suspected until blood tests for other routine examinations indicate an elevated globulin level. These cancer cells build up in the bone marrow and crowd out healthy cells. Ifx shows no monoclonal protein & free light chains are within normal range.

A gammopathy is an abnormal increase in the bodys ability to produce antibodies. A monoclonal protein is produced by the abnormal, cancerous or precancerous cells. While a small amount is normal, a large amount of protein in urine may indicate kidney disease. With the addition of the serum free light-chain (FLC) assay, the expanded monoclonal protein study provides even more diagnostic sensitivity for the monoclonal light-chain diseases such as primary amyloid and light-chain deposition disease; disorders that often do not have serum monoclonal proteins in high enough concentration to be detected and quantitated by PEL. TABLE 1. This test can be used to diagnose a kidney condition or see if a treatment is working. -A characteristic monoclonal band (M-spike) is often found on protein electrophoresis (PEL) in the gamma globulin region and, more rarely, in the beta or alpha-2 regions.

Some insurers require referrals, or may have additional requirements for certain medical care. It is recommended that serum and urine protein electrophoresis (PEL) and immunofixation electrophoresis (IFE) be performed as part of the diagnostic algorithm (eg, MPSS / Monoclonal Protein Study, Serum and MPSU / Monoclonal Protein Study, 24 Hour, Urine). Depending on the results of those tests, more testing may be done. The chance of getting MGUS grows with age, but it is not common. There is something called MGUS, or monoclonal gammopathy of uncertain significance--which means that physicians can make guesses about what this means to you in the long-term but can't tell you for sure.
