    Additional Manufacturer Narrative · 1

    THE INVESTIGATION DETERMINED THAT MULTIPLE LOWER AND HIGHER THAN EXPECTED VITROS TSH RESULTS WERE OBTAINED ON MULTIPLE PROFICIENCY AND QUALITY CONTROL SAMPLES USING TWO DIFFERENT VITROS TSH REAGENT LOTS PROCESSED ON TWO VITROS ECIQ IMMUNODIAGNOSTIC SYSTEMS. THE INVESTIGATION WAS UNABLE TO DETERMINE THE ASSIGNABLE CAUSE FOR THE LOWER THAN EXPECTED TSH PROFICIENCY RESULTS OBTAINED FROM ECI #1 USING TSH LOT 4920 AND LOT 4950. THERE WERE NO INDICATION VITROS TSH REAGENT LOTS 4920, 4950, OR VITROS ECI #1 MALFUNCTIONED. THE INVESTIGATION DETERMINED THE ASSIGNABLE CAUSE FOR THE LOWER THAN EXPECTED TSH PROFICIENCY RESULTS OBTAINED FROM ECI #2 USING TSH LOT 4920 AND LOT 4950 WAS INSTRUMENT RELATED, AS A WITHIN-RUN TSH PRECISION TEST ON ECI #2 WAS OUTSIDE OF ORTHO GUIDELINES, INDICATING THE VITROS ECI #2 SYSTEM WAS NOT PERFORMING AS INTENDED. THERE WAS NO INDICATION VITROS TSH REAGENT LOT 4920 OR 4950 MALFUNCTIONED. IN ADDITION, THERE WAS NO DISCUSSION ON PRE-ANALYTICAL SAMPLE STORAGE AND HANDLING OF THE PROFICIENCY SAMPLES. THEREFORE, A PRE-ANALYTICAL SAMPLE HANDLING ISSUE CANNOT BE RULED OUT AS A CONTRIBUTOR TO THIS EVENT.

BIASED RESULTS OF THE DIRECTION AND MAGNITUDE OBSERVED COULD LEAD TO INAPPROPRIATE PHYSICIAN ACTION.
