Part Description

LP29071-5   Immunoglobulin light chains.free
Healthy patients have the majority of light chains in serum bound to heavy chains. Low levels of free light chains (unbound) are normal due to the over-production and secretion of free light chains by plasma cells. In the kidneys, the free light chains are selectively reabsorbed by the tubular cells, so their presence in urine is likely due to secretion into the urinary tract. Elevation of monoclonal free light chains in serum or urine signal malignant plasma cell proliferation (multiple myeloma), primary amyloidosis, or light chain deposition disease. Elevation of polyclonal free light chains suggests autoimmune diseases such as systemic lupus erythematosus.
