WebThe test measures the levels of specific types of free light chains, known as kappa and lambda, and also the ratio between the two. Normal test results for free light chains are: 3.3 to 19.4 mg/L kappa free light chains. 5.7 to 26.3 mg/L lambda free light chains. 0.26 to 1.65 ratio of kappa/lambda. If your results are higher or lower, it may ... WebA kappa free light chain test is a quick blood test that measures certain proteins in your blood.
