Light Chains are proteins made by white blood cells. It is a component (the other is Kappa Light chain) of an immunglobulin molecule and formed by linking up with heavy chains. The immun system B cells in lymphoid tissue possess kappa or lambda light chains. They are in a certain proportion to each other but if the ratio balance is altered, this means that a neoplastic pathology has occured (multiple myeloma or Bence Jones proteinuria).
Normally, the white cells make a small amount of light chains which do not bind to heavy chains, instead released in blood.
Interpretation:If the amount of light Kappa or Lambda chains are higher than normal, it may be the sign of a disorder of white blood cells and amyloidosis which is a pathological foreign protein build up in different tissues.
