Additional Codes

Epic Code

Order  LAB438,  Urine Protein Electrophoresis with Monoclonal Quantitation

Please Note: Additional CPT and professional fee for pathologist’s interpretation may be applied.

Methodology

 

This test quantifies monoclonal proteins by electrophoresis and
densitometry.  If not previously known, to Identify the
monoclonal protein, an IFE on Urine will be ordered as indicated by
the pathologist.
