also known as Beta globulin in Urine by Electrophoresis
Urine protein electrophoresis evaluates the major protein fractions found in urine. It normally includes some albumin, and often faint bands of alpha 1 and beta globulin. Excess protein loss is often a manifestation of renal disease but may also be caused by fever, thyroid disorders, congestive heart disease, hypertension, stress, cold exposure, or following excess muscle activity as in seizures. The pattern of proteins present may suggest a glomerular leak, decreased tubular reabsorption, or a combination of the two. Monoclonal free light chains may also be detected in urine in patients with gammopathies including light chain disease, multiple myeloma, Waldenstrom's macroglobinemia, amyloidosis, and myeloproliferative disorders. Alternative Names: Globulins, 24-Hour Urine, UPE, and UPEP
