Diazyme's Free Light Chain Lambda (λ) assay has an excellent linearity range up to 4000 mg/L. The method comparison gave a linear regression coefficient of 0.972, a slope of 1.054 and y-intercept of 0.636 mg//L. Precision of the assay was evaluated according to the CLSI EP5-A guidelines and has a Within-Run precision from 1.1% - 6.5% and a Total Precision of 1.1% - 11.4%. The Lambda assay displays outstanding sensitivity with an LOD of 2.9 mg/L; LOQ of 6.1 mg/L; and a LOB determined to be 1.7 mg/L.
Human Lambda (λ) Free Light Chain Assay is based on a latex enhanced immunoturbidimetric assay. Lambda FLC in the sample binds to specific anti-Lambda FLC antibody, which is coated on latex particles, and causes agglutination. The degree of the turbidity caused by agglutination can be measured optically and is proportional to the amount of Lambda FLC in the sample. The instrument calculates the Lambda FLC concentration by interpolation of obtained signal of a 6-point calibration curve prepared from calibrators of known concentrations.
The Diazyme Human Lambda (λ) Free Light Chain Assay is in-tended as a latex particle enhanced immunoturbidimetric assay for the quantitative determination of Lambda Free Light Chain (FLC) concentration in serum on Hitachi 917 analyzers. The measurement of Kappa FLC in conjunction with Lambda FLC aids in the diagnosis of multiple myeloma in conjunction with other laboratory findings. For in-vitro diagnostic use only.
