Clinical Significance

Protein electrophoresis evaluates the major protein fractions found in urine. It normally includes albumin, and often faint bands of alpha1 and beta globulin. Urinary protein electrophoresis is useful in classifying the type of renal damage, if present. Immunofixation is useful in characterizing M-components observed in the protein electrophoresis and in identifying light-chain disease.
