INVESTIGATION: DEVICE HISTORY RECORD: NO ANOMALY WAS FOUND DURING THE MANUFACTURING, CONTROL AND PACKAGING PROCESSES. COMPLAINT ANALYSIS: AT THE DATE OF THE INVESTIGATION, NO OTHER COMPLAINTS WERE RECORDED FOR VIDAS LYM 1009796460. TESTS/ANALYSIS PERFORMED. TWO (2) SAMPLES IDENTIFIED 1 AND 2 WERE RECEIVED FROM THE CUSTOMER. SAMPLES WERE THAWED ON RECEIPT. COMPLAINTS LABORATORY PERFORMED SEVERAL TESTS: STUDY OF INTERNAL SAMPLES CONTROL CHARTS: THIS ANALYSIS WAS CARRIED OUT: ON FOUR (4) INTERNAL SERA VIDAS LYM WITH TARGETS BETWEEN 0.11 TO 2.42 VT. USING SEVEN (7) BATCHES OF VIDAS LYM INCLUDING THE BATCHES MENTIONED BY THE CUSTOMER. ALL VALUES ARE WITHIN THEIR SPECIFICATIONS, CUSTOMER¿S LOT IS IN THE TREND OF THE OTHER LOTS. STUDY ON INTERNAL SAMPLES: THE COMPLAINTS LABORATORY TESTED FOUR (4) INTERNAL SAMPLES WITH FOLLOWING TARGETS: 0.39 VT, 0.34 VT, 0.11 VT AND 2.29 VT ON THE RETAIN KIT 1009796460. SAMPLE RESULTS ARE WITHIN THEIR EXPECTED SPECIFICATIONS. NO BATCH CHANGES OBSERVED SINCE THE RELEASE DATE. STUDY ON CUSTOMER SAMPLES: TEST ON THE RETAIN KIT VIDAS LYM 1009796460. THE RESULTS OF SAMPLES 1 AND 2 WERE NEGATIVE WITH THIS BATCH. TEST ON ANOTHER METHOD - KITS RECOMLINE® BORRELIA IGG ET IGM. THE RESULTS OF SAMPLES 1 AND 2 WERE NEGATIVE. ROOT CAUSE ANALYSIS AND CONCLUSION: ACCORDING TO ALL INFORMATION ABOVE, NO ANOMALY WAS HIGHLIGHTED DURING THE CONTROL CHART ANALYSIS, THE ANALYSIS OF QUALITY DATA AND THE TESTS PERFORMED WITH THE RETAIN KIT FOR VIDAS LYM 1009796460. THE SAMPLES WERE NEGATIVE WITH 3 METHODS: VIDAS LYM AND RECOMLINE® BORRELIA (BOTH CONFIRMED DURING BIOMÉRIEUX INVESTIGATION) AS WELL AS WITH CHEMILUMINESCENCE SYNLAB AND POSITIVE WITH WESTERN BLOT EUROLINE EUROIMMUN (TWO (2) LAST RESULTS GIVEN BY THE CUSTOMER). THE WESTERNBLOT EUROLINE EUROIMMUN METHOD SHOWS 4 POSITIVE BANDS (OSPC BA, BB, BG AND BSP), BUT THEY ARE THE SAME ANTIGENIC COMMUNITY (OSPC). GIVEN THE DATA PROVIDED, THE PROBABLE CAUSE OF THIS DISCREPANCY IS AS FOLLOWS: 1/ ANTIBODIES MAY NOT PRESENT IN A DETECTABLE QUANTITY. IN THE EARLY STAGE, AN ANTIBIOTIC TREATMENT MAY PREVENT THE DEVELOPMENT OF DETECTABLE ANTIBODIES. IT IS ESTIMATED THAT IN 50% OF SUBJECTS IN THE PRIMARY STAGE OF DISEASE, ANTIBODY LEVELS REMAIN BELOW THE DETECTABLE THRESHOLD. THE PATIENT HAD TICK BITE IN EARLY JUNE AND THE VIDAS TESTS WERE CARRIED OUT IN MID-JUNE AND AT THE END OF JUNE. PATIENT WAS TREATED WITH ANTIBIOTICS. POSSIBILITY OF FALSE POSITIVE RESULTS OF WESTERN BLOT EUROLINE EUROIMMUN. ACCORDING TO THE VIDAS LYM PACKAGE INSERT: RESULTS AND INTERPRETATION : IN CASE OF CLINICAL SUSPICION (TICK BITE, NEUROLOGICAL SYMPTOMS, ETC.), COLLECT ANOTHER SAMPLE LATER. LIMITATIONS OF THE METHOD: NEGATIVE RESULTS WITH THE VIDAS LYME IGM AND VIDAS LYME IGG ASSAYS DOES NOT RULE OUT THE POSSIBILITY OF B. BURGDORFERI INFECTION IN A PATIENT. PATIENTS IN THE EARLY STAGES OF INFECTION OR WHO HAVE UNDERGONE ANTIBIOTIC THERAPY, MAY NOT PRODUCE MEASURABLE IGM AND IGG. PATIENTS WITH CLINICAL HISTORY AND/OR SYMPTOMS SUGGESTIVE OF LYME BORRELIOSIS, BUT WITH NEGATIVE TEST RESULTS, SHOULD BE REPORTED AS "NO DETECTABLE ANTIBODIES TO B. BURGDORFERI". A SECOND SPECIMEN SHOULD BE COLLECTED 4-6 WEEKS LATER BASED ON THE ABOVE DATA, THERE IS NO RECONSIDERATION OF PERFORMANCE OF VIDAS® LYME IGM (LYM) 1009796460.
