    (B)(4). 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 AND/OR THE ARCHITECT HAVAB-IGG ASSAY (LIST NUMBER 6C29). THIS OCCURS DUE TO REAGENT MEDIATED SAMPLE CARRYOVER OF HIGH B-HCG SAMPLES CAUSED BY THE ARCHITECT RUBELLA IGG ASSAY SPECIFIC DILUENT COMPONENT OR THE ARCHITECT HAVAB-IGG MICORPARTICLE COMPONENT ON AN ARCHITECT I1000SR SYSTEM. ARCHITECT RUBELLA IGG IS CURRENTLY BEING REFORMULATED.
