Use

Used for identifying monoclonal gammopathies using random urine specimens through analysis of urine proteins such as monoclonal immunoglobulin light chains, which are characteristic of conditions such as multiple myeloma, primary systemic amyloidosis, and light-chain deposition disease. The test’s components include protein electrophoresis, protein/creatinine ratio, and when indicated, M‑protein mass‑fix analysis, providing both detection and semi‑quantitative evaluation of monoclonal proteins in urine. The presence of monoclonal light chains may have renal implications such as Fanconi syndrome or light-chain deposition disease and reflect systemic plasma cell disorders.
