Notes
Please note: This test measures primarily kappa and lambda light chains that are bound to the heavy chains of IgG, IgA, or IgM in urine; however, some free light chains can also be detected with this method. If free light chain multiple myeloma is suspected, please order free kappa and free lambda light chains for a more accurate measurement of the free light chains.
