Approximately 11% of patients with MM have a completely normal serum PEL, with the monoclonal protein only identified by IFE. If the free light chain results do not agree with other clinical or laboratory findings, or if the sample is from a patient that has previously demonstrated antigen excess, the result must be checked by retesting at a higher sample dilution.
