    Additional Manufacturer Narrative · 0

    SENSOR (B)(6) HAS BEEN RETURNED AND INVESTIGATED. THE SENSOR PLUG IS FULLY SEATED AND NO PHYSICAL DAMAGE IS OBSERVED ON THE SENSOR PATCH. EXTRACTED DATA FROM THE RETURNED SENSOR USING APPROVED SOFTWARE. THE SENSOR WAS FOUND TO BE IN SENSOR STATE 5 (INDICATING NORMAL TERMINATION). VISUAL INSPECTION HAS BEEN PERFORMED ON THE SENSOR PLUG ASSEMBLY AND WATER-BASED LIQUID CONTAMINATION WAS OBSERVED ON PCBA (PRINTED CIRCUIT BOARD ASSEMBLY) TRIANGLE. THE CURRENT WAS APPLIED TO THE SENSOR TO PERFORM ACCURACY TESTING WHILE IN THE TEST FIXTURE. ALL RESULTS WERE WITHIN SPECIFICATION. POISE VOLTAGE AND SENSOR THERMISTOR TESTING WERE BOTH WITHIN SPECIFICATION, INDICATING THE SENSOR WAS PROVIDING ACCURATE GLUCOSE READINGS. THE PASSING OF ALL TESTS DURING THE INVESTIGATION INDICATES THAT THE WATER-BASED LIQUID CONTAMINATION DID NOT IMPACT THE SENSOR¿S ABILITY TO GENERATE AN ACCURATE GLUCOSE READING. THEREFORE, ISSUE IS NOT CONFIRMED. ALL PERTINENT INFORMATION AVAILABLE TO ABBOTT DIABETES CARE HAS BEEN SUBMITTED.
