Immunofixation of urine is useful in evaluation of monoclonal free light chains and other monoclonal gammopathies seen in light chain disease, multiple myeloma, Waldenstrom's macroglobulinemia, amyloidosis, and other lymphoproliferative disorders. Increased polyclonal free light chains in urine may be seen in glomerular leak syndromes and in infection or inflammation. The immunofixation urine test or urine immunofixation test detects the presence and measures the amount of certain types of proteins in the urine. These proteins are known as immunoglobulins. Abnormal immunoglobulins in the urine suggest the presence of disease.
