Immunofixation electrophoresis involves protein separation on a gel through electrophoresis and visualization with specific antibodies for identifying abnormal immunoglobulins. This technique in urine samples provides diagnostic information about abnormal proteins, mainly monoclonal immunoglobulins. This test is indicated for detecting abnormal urine proteins in haematological disorders like multiple myeloma and related plasma cell disorders, aiding in diagnosis, prognosis, and treatment monitoring.
