IFE Interpretation by report
Test Information: Total Protein
Total urinary protein is determined nephelometrically
by adding the albumin and Kappa and/or Lambda light
chains. This value may not agree with the total
protein as determined by chemical methods, which
characteristically underestimate urinary light chains.
