Serum Kappa/Lambda Free Light Chain Assay Update

Effective September 28th, 2020, a new generation of the serum kappa/lambda free light chain assay has been implemented.

With the implementation of the new generation of the assay there is an approximately 20% negative bias for kappa free light chains in serum containing >20 mg/dL kappa free light chain.  This may affect the trending for patient who are serially monitored by this assay. Continue Reading
