A kappa free light chain test is a quick blood test that measures certain proteins in your blood. High levels of these proteins may mean you have a plasma cell disorder. A healthcare provider might order a kappa free light chain test if you have symptoms such as bone pain or fatigue.
A free light chains test measures the amount of lambda and kappa free light chains in the blood. If the amount of free light chains is higher or lower than normal, it can mean you have a disorder of the plasma cells.
What does it mean if your lambda or kappa light chain is high? Light chain myeloma can be classified as lambda or kappa light chain myeloma, depending on which type the cancerous cells...
The serum free light chain assay provides the concentration of the two light chains that are found in the body — the kappa and lambda light chains — and the ratio between these light chains. People with multiple myeloma typically have abnormally high levels of either kappa or lambda light chain, and an abnormal ratio between the two light ...
A free light chains test measures the amount of lambda and kappa free light chains in your blood. If the amount of free light chains is higher or lower than normal, it may be a sign of a disorder of the plasma cells.
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 mean you have a problem with your plasma cells, such as multiple myeloma.
High calcium levels (hypercalcemia) can cause symptoms such as fatigue, weakness, and confusion. Blood tests measuring levels of lactic dehydrogenase (LDH) and beta-2 microglobulin (B2M) are also often done. levels of these substances are used to help determine the stage of the myeloma.
Free light chains ranges. To better understand FLC test results, these are the normal ranges: Normal values for kappa, lambda and FLC ratio: Kappa light chain concentration range: 3.3-19.4 mg/mL; Lambda light chain concentration range: 5.7- 26.3 mg/mL ; FLC (kappa/lambda) ratio: 0.26 -1.65
AL amyloidosis (amyloid light chain or primary amyloidosis) is a rare disease that happens when abnormal light chain proteins in your body gather on your organs and tissues. It's a serious illness that may become chronic or may cause life-threatening medical conditions.
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 mean you have a problem with your plasma cells, such as multiple myeloma.
