    DATE FOR THIS REPORT 08/12/2013. DATE RECEIVED BY MANUFACTURER 08/12/2013. FOLLOW UP REPORT 1. ADDITIONAL INFORMATION / DEVICE EVALUATION. DEVICE EVALUATED BY MANUFACTURER: YES. (B)(4) THE COMPLAINT ALLEGED THAT FIVE PATIENTS GENERATED DISCREPANT RESULTS WHEN USING THE COBAS AMPLIPREP / COBAS TAQMAN (CAP/CTM) (B)(6) V2.0 CE-IVD TEST. THIS MDR IS FOR PATIENT LABORATORY NUMBER (B)(6). MDRS 2243471-2013-00015. 2243471-2013-00016, 2243471-2013-00018, 2243471-2013-00019 ADDRESS THE OTHER FOUR PATIENT SAMPLE RESULTS. THE INITIAL PATIENT DRAW WAS TESTED ON (B)(6) 2012 AND GENERATED AN (B)(6) TARGET NOT DETECTED (TND) RESULT. A SUBSEQUENT BLOOD DRAW TESTED ON (B)(6) 2013 GENERATED AN (B)(6) LOG TITER OF 3.23. THE PHYSICIAN QUESTIONED THIS RESULT. THIS SAMPLE WAS REPEATED ON (B)(6) 2013 AND GENERATED AN (B)(6) TARGET NOT DETECTED (TND) RESULT. ALL CONTROLS WERE VALID AND IN RANGE FOR ALL RUNS TESTED. THE SAMPLE ADDRESSED IN THIS REPORT - (B)(6)- WAS NOT PROVIDED FOR INVESTIGATIVE TESTING. RETAIN KIT TESTING MET SPECIFICATIONS. THE CAUSE OF THE HIGH TITER RESULT OF 3.23 LOG IS UNKNOWN. THE MEDICAL ASSESSMENT STATES THAT IT IS POSSIBLE THAT PATIENTS HAD INTERCURRENT ACUTE ILLNESS, SUCH AS THE FLU, CAUSING A VIRAL "BLIP". PATIENTS THAT WERE POSSIBLY NON-ADHERENT TO MEDICATIONS COULD CAUSE A RISE IN VIREMIA AND SUBSEQUENTLY TOOK THEIR MEDICATIONS AS DIRECTED, CAUSING THE VIRAL LOAD TO DECREASE. THE ISSUE COULD ALSO POSSIBLY HAVE BEEN CAUSED BY SAMPLE HANDLING INTRODUCING CONTAMINATION AFTER DISPENSING FROM THE PRIMARY. HOWEVER, THE ROOT CAUSE OF THE ISSUE CANNOT BE DEFINITIVELY DETERMINED. AS THE RETAIN KIT TESTING MET SPECIFICATIONS, THERE IS NO INDICATION THAT THE ISSUE OF DISCREPANT RESULTS WAS DUE TO A PRODUCT NON-CONFORMANCE OR MALFUNCTION. (B)(4)
