Monoclonal Protein Study, Expanded Panel, Serum

IFE FLC
Example Reports
Abnormal
Enhanced Report
Normal

Ordering Recommendation

Aids in the diagnosis and monitoring of monoclonal gammopathies. Panel includes serum free light chain testing, eliminating the need for urine monoclonal studies as part of initial screening. Use to detect, quantify, and characterize serum monoclonal protein.

New York DOH Approval Status

This test is New York state approved.

Interpretive Data

Undetected antigen excess is a rare event but cannot be excluded. Free light chain results should always be interpreted in conjunction with other clinical and laboratory findings.

Note

A copy of the graph will follow the final report. This assay is highly sensitive to increasing concentrations of monoclonal free kappa or free lambda light chains in the serum of patients with evolving or relapsing myelomas.
