WebAbnormal free light chain production has also been reported to be prognostic of a worse outcome in multiple myeloma and chronic lymphocytic leukaemia. An abnormal light-chain ratio has been defined as a kappa to lambda chain ratio of less than 0.26 or more than 1.65.

Serum Free Light Chain Assays ©2011 Laboratory Corporation of America ... WebEach type of immunoglobulin is composed of four protein chains: 2 identical heavy chains and 2 identical light chains. A particular plasma cell will produce only one type of immunoglobulin. Normally, there is a slight excess of free light chains produced, so low levels of free kappa and lambda chains are detected in the blood. References: WebJul 21, 2014 · Background: Detection of B cell clonality is useful for assisting in the diagnosis of B cell lymphomas. Clonality assessment can be accomplished through evaluation of KAPPA and LAMBDA light chain expression. Currently, only slide based methods are available for the majority of patient biopsies and do not detect light chain protein or … blue moanin bto
