    Description of Event or Problem · 0

    IT WAS REPORTED THAT WHILE USING BD TRUCOUNT¿ ABSOLUTE COUNTING TUBES ERRONEOUS RESULTS WERE OBSERVED AND REPORTED TO A CLINICIAN. THE NUMBER OF PATIENTS AFFECTED COULD NOT BE CONFIRMED AND NO SERIOUS INJURIES WERE REPORTED. THE FOLLOWING INFORMATION WAS PROVIDED BY THE INITIAL REPORTER: THE CD45 ABSOLUTE COUNT FOR THE 3 TUBES FOR THE PIP DOES NOT MATCH THUS THE ABSOLUTE COUNTS FOR THE LYMPHOCYTE MARKERS ARE INACCURATE. IT AFFECTED MANY RESULTS THAT WE HAVE TO REPEAT AND POSSIBLE OTHER RESULTS THAT WE HAVE ALREADY REPORTED THAT WE CAN NO LONGER REPEAT DUE TO SAMPLE STABILITY. WE DON'T KNOW IF THERE ARE SINGLE-TUBE ASSAY THAT WE REPORTED INCORRECTLY, LIKE I MENTIONED EARLIER IT WOULD BE HARD TO CATCH IT IN A SINGLE-TUBE ASSAY AND WE HAVE NOT RECEIVED ANY CALLS FROM OUR CLIENTS, YET. SO, WE DON'T KNOW THE ANSWER TO THE FOLLOWING QUESTIONS.
