SIEMENS HAS CONFIRMED THAT THE ISSUE NOTED IN THE DECEMBER 2013 FIELD ACTION IS NOT LIMITED TO ONLY SAMPLES >5.5 NG/ML (19.2 NMOL/L).

    Description of Event or Problem · 1

    THE CUSTOMER HAS REPORTED A DISCORDANT RESULT ON ONE PATIENT SAMPLE AFTER DILUTION FOR THE ANDROSTENEDIONE ASSAY ON AN IMMULITE 2000 INSTRUMENT WHEN USING REAGENT LOT 323. THE SAMPLE WAS FIRST RUN NEAT AND AS THE INITIAL RESULT WAS >5.5 NG/ML THE SAMPLE WAS DILUTED AND RE-RUN ON THE IMMULITE 2000 INSTRUMENT. THE CALCULATED DILUTED RESULT WAS LOWER THAN THE NEAT RESULT. THE INITIAL RESULT OBTAINED ON THE UNDILUTED SAMPLE WAS REPORTED TO THE PHYSICIAN(S). THERE WERE NO KNOWN REPORTS OF PATIENT INTERVENTION OR ADVERSE HEALTH CONSEQUENCES DUE TO THE DISCORDANT RESULT OBTAINED FOR THE ANDROSTENEDIONE ASSAY.
