Kappa and lambda light chains ratio
WebbFree light chains (FLC, quantitative assay) have been shown to be sensitive and specific for various light chain–associated disorders. In 110 patients with amyloidosis, the FLC kappa/lambda ratio was positive in 91% of patients (compared with 69% of patients) for serum immunofixation (IFE) and in 83% of patients for urine IFE.The combination of … Webbincreased amounts of either kappa or lambda free light chains, which can be measured in the blood. Consequently, the ratio of kappa to lambda light chains is abnormal in most patients and is a sensitive indicator for this disease. This test may be used to monitor progression and/or treatment.

In a healthy individual, the total kappa-to-lambda ratio is roughly 2:1 in serum (measuring intact whole antibodies) or 1:1.5 if measuring free light chains, with a highly divergent ratio indicative of neoplasm. The free light chain ratio ranges from 0.26 to 1.65. [1] Visa mer The immunoglobulin light chain is the small polypeptide subunit of an antibody (immunoglobulin). A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains. Visa mer There are two types of light chain in humans: • kappa (κ) chain, encoded by the immunoglobulin kappa locus Visa mer Only one type of light chain is present in a typical antibody, thus the two light chains of an individual antibody are identical. Each light chain is composed of two tandem Visa mer • Monoclonal antibody Visa mer The immunoglobulin light chain genes in tetrapods can be classified into three distinct groups: kappa (κ), lambda (λ), and sigma (σ). The divergence of the κ, λ, and σ isotypes preceded the radiation of tetrapods.
