If a monoclonal protein pattern is detected by IFE or FLC, a diagnosis of a monoclonal gammopathy is established. That's important in determining prognosis and treatment. I did this until I was able to get insurance and refused the big stuff until then. This has to be examined carefully. But sometimes it is uncovered while you're having blood tests done as part of an evaluation for some other problem or symptom. Finding M proteins in the blood or urine is usually a sign of disease. WebMonoclonal antibodies are immune system proteins that are created in the lab. Only one type of immunoglobulin (Ig) is overproduced when you have myeloma. In: Goldman-Cecil Medicine. If a monoclonal light chain is detected in the absence of an associated monoclonal heavy chain, an immunofixation electrophoresis specific for delta and epsilon chains is performed. 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). MONOCLONAL (adjective) The adjective MONOCLONAL has 1 sense: 1. forming or Extra protein is not used efficiently by the body and may impose a metabolic burden on the bones, kidneys, and liver. -Low-risk MGUS patients are defined as having an M-spike of less than 1.5 g/dL, IgG monoclonal protein, and a normal FLC K/L ratio (0.25-1.65), and these patients have a lifetime risk of progression to MM of less than 5%.
