Rarely, plasma cells can enter into the circulation and if they represent 20 percent or more of the blood cells, the condition is called plasma cell leukemia. Note that the percent of plasma cells in the bone marrow, assessed by flow cytometry, is not the value used in the diagnostic criteria above. The SFLC assay can detect abnormal levels of free light chains, which may be an indication of a plasma cell disorder. Most patients with untreated myeloma have a monoclonal immunoglobulin spike in serum, urine, or both. Is there a person or breakthrough we should celebrate? A negative urine or serum immunofixation result does not always rule out a plasma cell dyscrasia, as a nonsecretory or oligosecretory multiple myeloma can present with a negative immunofixation finding in both the urine and the serum. There are five types of heavy chains, and each type is represented by a specific letter: IgG, IgA, IgD, IgE and IgM. Typically, the monoclonal protein is discovered, and workup then ensues. C-reactive protein (CRP) is located in the area between the beta and gamma components.1, Serum protein electrophoresis commonly is performed when multiple myeloma is suspected.
