Correlation of the FLC kappa/lambda ratio produced by N Latex FLC assay is accurate for samples at both high- and low-end concentrations vs. the ratio produced by the FREELITE assay, which can be severely affected as shown in the graph above. ...
He had a slightly elevated serum kappa to lambda ratio of 2.21 and urine protein electrophoresis with 3% IgG kappa. He had no associated hypercalcemia, renal dysfunction, anemia or bone involvement and an unremarkable skeletal survey, but at that stage no confirmatory bone marrow biopsy. At that...

Kappa and lambda consist of a variable region and a constant region and can easily be differentiated by the antigenic properties of the constant region. The ratio of kappa to lambda is 70:30. Antibodies to the kappa light chain are reportedly useful in the identification of leukemias, ...

OCB were detected by isoelectric focussing, FLCK and FLCL (lambda) by immunonephelometry. White matter lesions (WM) on brain MRI was compared with OCB, CSF IgG/albumin ratio >12, FLCK >1.53 mg/L and FLCK/FLCL ratio >1.65 (upper reference limit for serum) and >3.3 (twice upper reference...
A urinary kappa/lambda ratio between 0.75-3 also ruled out a BJP. The use of kappa/lambda ratios, in conjunction with UPE, resulted in a 52% decrease in the volume of IFE during the course of this study, with 100% sensitivity for detecting BJP. 展开 ...
探讨血清中Kappa和Lambda轻链在恶性肿瘤患者中的表达情况。方法 采用 免疫比浊法对80例恶性肿瘤患者和20例健康体检者血清中Kappa和Lambda轻链进行检测。结果 肝癌组患者血清中K和入值均显著高于健康对照组,且差异有统计学意义(P<0.01);而v./X比值 与健康对照组比较,差异无统计学意义(P>0.05)。胃癌、肺癌、乳腺癌...
