Besides multiple myeloma, presence of M proteins in your blood may result in: Most people are diagnosed with MGUS during blood tests for other conditions that affect the bloods protein levels, such as a nerve disorder called peripheral neuropathy. 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. Ifx shows no monoclonal protein & free light chains are within normal range. These cancerous cells rapidly spread and crowd out the normal antibodies with M proteins, overtaking the healthy cells. There is no risk of monoclonal gammopathies in first-degree family members. My lab results say People with monoclonal gammopathy generally don't experience signs or symptoms. TABLE 1. Amyloidosis is a condition in which too much of a particular protein (amyloid) collects in the organs, so that they are not able to work normally. Several types of proteins are present in all tissue throughout the body, including the blood. What does this mean? 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.
