Monoclonal Protein Study, Expanded Panel, Serum
Also known as: IFE FLC
Use
Aids in the diagnosis and monitoring of monoclonal gammopathies. This panel includes serum free light chain testing, eliminating the need for urine monoclonal studies as part of initial screening. It is used to detect, quantify, and characterize serum monoclonal protein, which is crucial for managing conditions such as multiple myeloma and other related plasma cell disorders.
Special Instructions
Not provided.
Limitations
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. Results should not be used as the sole criteria for diagnosis, and clinical correlation is required.
