Free Light Chains (Kappa & Lambda), Serum in Bhopal

Free light chains, also known as kappa and lambda light chains, are proteins produced by plasma cells, a type of immune cells. This blood test quantifies the amount of free light chains or kappa and lambda chains inside the bloodstream. Usually the light chains link together with heavy chains (other proteins) to form antibodies. Free light chains (FLC) are the ones that are not part of whole (intact) immunoglobulins and are present in the blood.

Your doctor may recommend this test if he/she suspects plasma cell disorders. This test helps to detect, diagnose and monitor plasma cell disorders (also known as dyscrasias) such as primary amyloidosis, multiple myeloma and various other associated diseases. A free light chains test is often ordered with other tests to rule out or confirm a diagnosis.
