    Description of Event or Problem · 1

    A CUSTOMER REPORTED THAT HIGHER THAN EXPECTED THYROID STIMULATING HORMONE (HTSH) RESULTS, BELOW THE NORMAL REFERENCE RANGE, WERE GENERATED ON A UNICEL DXI 800 ACCESS IMMUNOASSAY SYSTEM FOR TEN PATIENTS. ACCESS HYPERSENSITIVE HTSH REAGENT (LOT 170013) AND ACCESS HTSH CALIBRATORS (LOT 018459) WERE USED IN CONJUNCTION WITH THE DXI 800 SYSTEM. THIS REPORT IS ONE OF TEN AND REPRESENTS THE RESULTS FOR PATIENT SEVEN. THE EXACT DATE ON WHICH THE ERRONEOUS PATIENT RESULT WAS GENERATED IS UNKNOWN AND WILL BE INFERRED AS (B)(6) 2011. SUBSEQUENT TESTING ON THE SAME INSTRUMENT GENERATED A RESULT OUTSIDE OF THE ASSAY'S STATED PRECISION CLAIM OF LESS THAN OR EQUAL TO 7%. ADDITIONAL TESTING ON AN ALTERNATE METHODOLOGY ALSO GENERATED A LOWER RESULT. THE INITIAL HTSH RESULT WAS REPORTED OUT OF THE LABORATORY AND WAS QUESTIONED BY THE CLINICIAN. WHILE THERE IS NO REPORT OF ADVERSE EVENT OR SERIOUS INJURY RELATED TO THIS EVENT, THE EFFECT TO PATIENT IS UNKNOWN.
