Clinical Significance
Protein electrophoresis is a well established technique routinely used to screen samples for protein abnormalities. Abnormalities may include monoclonal components, particularly Bence-Jones Protein and other urinary proteins. The test results should be used in conjunction with clinical and laboratory findings.
