My immunofixation interpretation came back High blood protein rarely causes signs or symptoms on its own. The next step is to use immunoelectrophoresis to determine the exact type of proteins in the blood. If the free light chain results do not agree with other clinical or laboratory findings, or if the sample is from a patient that has previously demonstrated antigen excess, the result must be checked by retesting at a higher sample dilution. What does this mean? Includes total protein, serum protein electrophoresis, and heavy-chain and light-chain typing (kappa and lambda).

What does monoclonal mean Afterwards, your doctor may Here's what, IVIG infusions provide your immune system with the antibodies it needs to help fight off infections. A blood screening and sometimes a urine screening is recommended. 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. What Is Severe Combined Immunodeficiency Disease (SCID)? 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.

ASM Press; 2016:112-124, Serum proteins are separated in an electric field according to their size, shape, and electric charge. Because MGUS is not harmful, it doesnt need to be treated. Morrow ES Jr. Allscripts EPSi. (MAH-noh-KLOH-nul PROH-teen) An antibody found in unusually large amounts in the blood or urine of people with multiple myeloma and other types of plasma cell tumors. Once a monoclonal gammopathy has been diagnosed, the size of the clonal abnormality can be monitored by PEL or FLC and, in some instances, by quantitative immunoglobulins.
