Additional Manufacturer Narrative

INTERNAL BIOMÉRIEUX INVESTIGATION WAS CONDUCTED. REVIEW OF MANUFACTURING QUALITY CONTROL RECORDS CONFIRMED ALL LOTS OF VIDAS LYME IGM PERFORMED IN ACCORDANCE WITH SPECIFICATIONS UPON PRODUCT RELEASE. RECENT CAP AND LAB QUALITY SURVEYS INDICATE ACHIEVEMENT OF THE EXPECTED RESULTS FOR VIDAS LYME IGM. ADDITIONAL TESTING WITH SIEMENS ENZYGNOST BORRELIOSIS IGM PROVIDES THE EXPECTED RESULT OF "NEGATIVE". THE INVESTIGATION REPRODUCED A PERCENTAGE OF "EQUIVOCAL" AND "POSITIVE" RESULTS AS IDENTIFIED BY THE VIDAS LYME IGM CUSTOMER AGAINST THE NATIONAL CONTROL (B)(4). BASED ON THE LAST (B)(6) SURVEY, PRESENCE OF RHEUMATOID FACTOR IN THE SAMPLE IS SUSPECTED AS THE LIKELY CAUSE. IN ADDITION, PRODUCT LIMITATIONS DESCRIBED IN THE VIDAS LYME IGM PACKAGE INSERT INDICATE: POSITIVE RESULTS IN THE VIDAS LYME IGG AND IGM ASSAY MUST BE INTERPRETED WITH CAUTION. CROSS-REACTIVITY MAY BE OBSERVED WITH CERTAIN DISEASES. CLINICAL SYMPTOMS, EPIDEMIOLOGICAL INFORMATION AND OTHER LABORATORY TEST RESULTS MUST ALL BE CONSIDERED IN ADDITION TO VIDAS LYME IGM AND IGG ASSAY RESULTS. INTERFERENCE MAY BE ENCOUNTERED WITH CERTAIN SERA CONTAINING ANTIBODIES DIRECTED AGAINST REAGENT COMPONENTS. FOR THIS REASON, ASSAY RESULTS SHOULD BE INTERPRETED TAKING INTO CONSIDERATION THE PATIENT'S HISTORY, AND THE RESULTS OF ANY OTHER TESTS PERFORMED. TESTING SHOULD BE DONE ONLY WHEN EXPOSURE HISTORY, EPIDEMIOLOGY AND CLINICAL SYMPTOMS SUGGEST LYME DISEASE. BASED ON THE RESULTS OF THE INVESTIGATION, VIDAS LYME IGM IS PERFORMING IN ACCORDANCE WITH THE SPECIFICATIONS/LIMITATIONS INDICATED IN THE PACKAGE INSERT. ALL OTHER TEST METHODS AND SURVEYS REVIEWED DURING THE INVESTIGATION INDICATE NO ANOMALY LINKED TO A LOT OR LOTS OF THE VIDAS LYME IGM ASSAY.
