WebbResults: MM was confirmed in 5 patients (5.43%; all patients had a highly abnormal kappa/lambda ratio). After the exclusion of the subjects with MM, the abnormal kappa/lambda ratio was found in 37 patients (42.5%); MM was excluded in all patients after careful hematological evaluation, including bone marrow biopsy in 12 cases. Serum free light-chain assays have been used in a number of published studies which have indicated superiority over the urine tests, particularly for patients producing low levels of monoclonal free light chains, as seen in nonsecretory multiple myeloma and AL amyloidosis. This is primarily because of the re-absorption of free light chains in the kidneys, creating a threshold of light chain production which must be exceeded before measurable quantities overflow into the u…
