    THE INVESTIGATION HAS DETERMINED THAT LOWER AND HIGHER THAN EXPECTED VITROS VANC RESULTS WERE OBTAINED FROM A TWO DIFFERENT LEVELS OF VITROS THERAPEUTIC DRUG MONITORING PERFORMANCE VERIFIER (TDM PV) FLUIDS TESTED ON A VITROS XT 7600 INTEGRATED SYSTEM. THE ASSIGNABLE CAUSE OF THE VITROS VANC RESULTS OF 15.55, 15.42, 19.99 AND 20.49 UG/ML WAS A SUBOPTIMAL CALIBRATION. THE ISSUE OCCURRED FOLLOWING CALIBRATION OF VITROS VANC REAGENT LOT 2514-56-2676. THE CALIBRATION RESPONSES AND PARAMETERS OBTAINED FROM THE AFFECTED CALIBRATION APPEARED ATYPICAL TO EXPECTED RESPONSES AND PARAMETERS. ACCEPTABLE PERFORMANCE WAS OBTAINED AFTER PERFORMING AN ADDITIONAL CALIBRATION EVENT WHERE THE CALIBRATION RESPONSES AND PARAMETERS APPEARED ATYPICAL TO EXPECTED RESPONSES AND PARAMETERS. THE CAUSE OF THE SUBOPTIMAL CALIBRATION IS UNKNOWN. THE ASSIGNABLE CAUSE OF THE VITROS VANC RESULTS OF <5.0, <5.0, <5.0, <5.0 UG/ML AND 7.44 UG/ML COULD NOT BE DETERMINED. BASED ON HISTORICAL QUALITY CONTROL RESULTS, A VITROS VANC REAGENT LOT 2514-56-2676 WAS PERFORMING AS INTENDED PRIOR TO THE EVENT. CONTINUAL TRACKING AND TRENDING OF COMPLAINT DATA HAS NOT IDENTIFIED ANY SIGNALS TO SUGGEST THERE IS A SYSTEMIC QUALITY ISSUE WITH VITROS VANC REAGENT LOT 2514-56-2676. THE VITROS VANC RESULTS SHIFTED LOW ON BOTH VITROS TDM PV LEVELS USING PACK ID (B)(4) AND CALIBRATION CURVE 3751. IT IS NOTED THAT ACCEPTABLE VITROS VANC RESULTS WERE OBTAINED FROM BOTH TDM PV LEVELS PRIOR TO THE EVENT USING PACK ID (B)(4). IN ADDITION, CALIBRATION CURVE 3751 WAS IN USE SINCE VITROS VANC REAGENT LOT 2514-56-2676 WAS INITIALLY PUT INTO USE ON 30 JANUARY 2025. THIS INDICATES THE EVENT WAS NOT REAGENT PACK OR CALIBRATION DRIVEN. DIAGNOSTIC WITHIN-RUN PRECISION TESTING TO ASSESS THE PERFORMANCE OF THE VITROS XT 7600 INTEGRATED SYSTEM WAS NOT PERFORMED, THEREFORE, AN INSTRUMENT RELATED PERFORMANCE ISSUE CANNOT BE RULED OUT AS CONTRIBUTING TO THE EVENT. HOWEVER, ACCEPTABLE VITROS VANC LOT 2514-56-2676 PERFORMANCE WAS OBTAINED AFTER CALIBRATING WITH AN ALTERNATE REAGENT PACK WITHOUT TAKING ANY ACTION TO OPTIMIZE THE VITROS XT 7600 INTEGRATED SYSTEM. THEREFORE, AN INSTRUMENT RELATED PERFORMANCE ISSUE DID NOT LIKELY CONTRIBUTE TO THE EVENT.
