Intended Use: The random urine protein electrophoresis test is used to evaluate individuals with renal disorders, and to screen for free monoclonal immunoglobulin light chains (Bence Jones proteins).
Additional Information: A trace of albumin is commonly seen in normal patients. Monoclonal free immunoglobulin light chains and/or intact immunoglobulins may be detected in individuals with multiple myeloma and other B-cell lymphoproliferative disorders.
