Kappa/Lambda Light Chains Free With Ratio details
What Kappa/Lambda Light Chains Free With Ratio shows
Free light chains are small antibody pieces, of two types called kappa and lambda, that plasma cells release into the blood. The kappa/lambda ratio is calculated by dividing the free kappa result by the free lambda result. It is used to help evaluate and monitor plasma cell disorders, including monoclonal gammopathies, multiple myeloma, and AL amyloidosis. A ratio that is clearly too high or too low suggests that one group of plasma cells is overproducing one type of light chain. When both light chains rise together, the ratio often stays normal, which is commonly seen with reduced kidney function or inflammation. It is interpreted alongside serum protein electrophoresis and immunofixation.
Tests that include Kappa/Lambda Light Chains Free With Ratio
The Kappa/Lambda Light Chains, Free with Ratio, Serum test measures the amount of kappa and lambda free light chains (FLCs) in the blood and calculates the kappa to lambda ratio. It is used to assist in the diagnosis of plasma cell disorders, including multiple myeloma, primary amyloidosis, monoclonal gammopathy of unknown significance (MGUS), Waldenström’s macroglobulinemia, and related disorders. It is also used to monitor disease activity and treatment [1].
