What is it indicated for?
In-vitro diagnostic reagents for the quantitative determination of free light chains (FLC), type kappa or type lambda in human serum and EDTA-plasma. FLC measurements are used as an aid in the diagnosis and monitoring of multiple myeloma (MM) and as an aid in the diagnosis of amyloidosis (AL) in conjunction with other laboratory and clinical findings.
The response category assignment of ‘Complete Response’ for the monitoring of MM, is reliant upon the combination of clinical history and other tests including protein electrophoresis, immunofixation and bone marrow, imaging and urine assessments.
Indications for use as stated in the FDA summary.
