Patient 1
DATE OF REPORT 4/8/2014. DATE RECEIVED BY MANUFACTURER 4/8/2014. DEVICE EVALUATED BY MANUFACTURER: YES. RESULT: DEVICE PERFORMED ACCORDING TO SPECIFICATIONS. CONCLUSION: NO FAILURE DETECTED AND PRODUCT WITHIN SPECIFICATION. THE PATIENT TESTED (B)(6) ON (B)(6) 2013. A NEW SAMPLE FROM THE SAME PATIENT WAS COLLECTED ON (B)(6) 2014 AND GENERATED A (B)(6) RESULT. THE SAME SAMPLE WAS TESTED ON (B)(6) 2014, ALONG WITH THE FIRST SAMPLE AND BOTH GENERATED (B)(6) RESULTS. ADDITIONAL INFORMATION WAS RECEIVED THAT GENOTYPING WAS ALSO PERFORMED ON THE PATIENT SAMPLE COLLECTED (B)(6) 2014 WITH THE SIEMEN'S LIPA TEST ON (B)(6) 2014 , BUT THE RESULT WAS VERY WEAK AND WAS DETERMINED BY THE PHYSICIAN TO BE (B)(6). SUBSEQUENT TESTING OF THE OLDER SAMPLE FROM (B)(6) 2013 GENERATED A RESULT OF (B)(6). ANALYSIS OF RAW DATA SUBMITTED BY THE CUSTOMER INDICATED THAT THE (B)(6) RESULT GENERATED ON (B)(6) 2014 DID NOT SHOW ANY SIGNS OF PCR INHIBITION THAT COULD HAVE LED TO THE (B)(6) RESULT. THE (B)(6) TARGET SIGNAL OF THE (B)(6) 2014 (B)(6) RESULT WAS ROBUST., ELIMINATING THE POSSIBILITY OF THE (B)(6) RESULT HAVING BEEN DUE TO A LOW AMOUNT OF (B)(4) TARGET MATERIAL IN THE SAMPLE. IT IS POSSIBLE THAT A SAMPLE MIX-UP COULD HAVE OCCURRED BUT THAT CANNOT BE CONFIRMED. ALTHOUGH REQUESTED, THE COMPLAINT SAMPLE WAS NOT AVAILABLE FOR INVESTIGATIVE TESTING. TESTING OF THE COMPLAINT KIT LOT MET SPECIFICATIONS. BASED ON THE INFORMATION AVAILABLE, THERE IS NO INDICATION OF A PRODUCT NON-CONFORMANCE. THE CAUSE OF THE (B)(6) RESULT GENERATED WITH THE CAP/CA (B)(4) TEST CANNOT BE DETERMINED. (B)(4).
