    Narratives

    Additional Manufacturer Narrative · 1

    THE CUSTOMER CALLED THE TECHNICAL SOLUTIONS CENTER (TSC) ABOUT THE DISCORDANT EPO RESULT. THE CUSTOMER STATED THAT THE LABORATORY RUNS OTHER ASSAYS (SUCH AS VITAMIN B12 AND FOLATE) THAT USE THE DILUTION WELL AND THAT THERE ARE NO PROBLEMS WITH THOSE ASSAYS. BASED ON THIS, THE TSC SPECIALIST DETERMINED THAT THE INSTRUMENT DID NOT REQUIRE A FIELD SERVICE ENGINEER TO INSPECT. THE INSTRUCTIONS FOR USE (IFU) FOR THE EPO ASSAY ON THE IMMULITE 2000 INSTRUMENT DOES INDICATE THAT THE ASSAY HAS LIMITATIONS. THE IFU STATES: "HETEROPHILIC ANTIBODIES IN HUMAN SERUM CAN REACT WITH THE IMMUNOGLOBULINS INCLUDED IN THE ASSAY COMPONENTS CAUSING INTERFERENCE WITH IN VITRO IMMUNOASSAYS." THE CAUSE OF THE DISCORDANT EPO RESULT IS UNKNOWN.
