    It is not clear whether the N Latex Free Light Chain (Siemens FLC) is FDA cleared for anything but MGUS monitoring. SMM progression to MM was discussed but it wasn't clearly stated that FDA approved this particular test for this purpose. Can you please clarify?
    Also, how does a physician (or patient) verify which test was performed and where? Must we really call the laboratory each time? Given the importance as a tumor marker, and the need for duplicate testing when changing labs/vendors (as is often the case when traveling, changing insurance, or just adapting to 'cheapest bidder' hospital practices, this puts a huge burden on physicians and patients that few appreciate enough to follow-up I suspect.
