    Narratives

    Additional Manufacturer Narrative · 1

    (B)(4). A PRODUCT DEFICIENCY HAS BEEN IDENTIFIED. WITH A UNIQUE COMBINATION OF INSTRUMENT AND REAGENT CONDITIONS THERE IS A POTENTIAL FOR SAMPLE CARRYOVER WHICH CAN RESULT IN FALSELY ELEVATED B-HCG CONCENTRATIONS ON THE ARCHITECT I1000SR SYSTEM. NEGATIVE SAMPLES HAVE RETURNED BOTH POSITIVE AND GREY ZONE B-HCG RESULTS WHEN A HIGH CONCENTRATION B-HCG SAMPLE IS ASSESSED PRIOR TO THE NEGATIVE SAMPLE WITH ARCHITECT TOTAL B-HCG (LIST NUMBER 7K78/6C21) ON AN I1000SR INSTRUMENT WHICH ALSO UTILIZES THE ARCHITECT RUBELLA IGG (LIST NUMBER 6C17) ASSAY. FURTHER INVESTIGATION OF THIS QUALITY ISSUE WILL BE CONDUCTED. AN INVESTIGATION IS IN PROCESS.
