    THE COMPLAINT INVESTIGATION FOR FALSELY DEPRESSED ALINITY I STAT HIGH SENSITIVITY TROPONIN-I RESULTS INCLUDED A REVIEW OF DATA AND INFORMATION PROVIDED BY THE CUSTOMER, SEARCH FOR SIMILAR COMPLAINTS, TICKET TRENDING REVIEW, LABELING REVIEW, DEVICE HISTORY RECORD REVIEW, FIELD DATA REVIEW, AND IN HOUSE TESTING. DATA AND INFORMATION PROVIDED BY THE CUSTOMER WERE REVIEWED AND SUPPORT THE COMPLAINT ISSUE WITHOUT INDICATION FOR ANY ADDITIONAL ISSUE. REVIEW OF TRACKING AND TRENDING FOR THE ALINITY I STAT HIGH SENSITIVE TROPONIN-I ASSAY DID NOT IDENTIFY AN INCREASE IN COMPLAINT ACTIVITY RELATED TO THE COMPLAINT ISSUE. ADDITIONALLY, AN INCREASE IN COMPLAINT ACTIVITY WAS NOT IDENTIFIED FOR REAGENT LOT 75636UD00. DEVICE HISTORY RECORD REVIEW DID NOT IDENTIFY ANY NONCONFORMANCES, POTENTIAL NONCONFORMANCE OR DEVIATIONS ASSOCIATED WITH THE LOT NUMBER. IN HOUSE ACCURACY TESTING WAS COMPLETED FOR THE COMPLAINT LOT 75636UD00 USING PANELS WHICH MIMIC PATIENT SAMPLES USING AN IN-HOUSE RETAINED KIT STORED AT THE RECOMMENDED STORAGE CONDITION. ALL SPECIFICATIONS WERE MET INDICATING THAT THE LOT IS PERFORMING ACCEPTABLY. THE OVERALL PERFORMANCE OF ALINITY I STAT HIGH SENSITIVE TROPONIN-I REAGENTS WAS REVIEWED USING DATA GATHERED FROM CUSTOMERS WORLDWIDE. THE PATIENT MEDIAN VALUES FOR LOTS 75633UD00 AND 75638UD00 (WHICH CONTAIN THE SAME BULK MATERIAL AS LOT 75636UD00) ARE WITHIN THE ESTABLISHED LIMITS AND COMPARABLE TO THE HISTORICAL REAGENT LOT PERFORMANCE. A REVIEW OF INSTRUMENT LOGS (ALINITY I STAT HIGH SENSITIVE TROPONIN-I RESULTS DATA) WAS PERFORMED. THE ANALYSIS SHOWED THAT THE COMPLAINT KIT REPEATEDLY TRIGGERED MESSAGE CODE 1044 AND SHOWED MUCH LOWER CORRECTED SIGNAL COUNTS FOR CONTROL LEVELS 1 AND 2 COMPARED TO OTHER KITS, INDICATING THAT THE PERFORMANCE OF THE COMPLAINT KIT WAS COMPROMISED. LABELING WAS REVIEWED AND SUFFICIENTLY ADDRESSES THE CUSTOMER'S ISSUE. BASED ON THE INVESTIGATION, NO SYSTEMIC ISSUE OR DEFICIENCY WITH THE ALINITY I STAT HIGH SENSITIVITY TROPONIN-I ASSAY FOR LOT 75636UD00 WAS IDENTIFIED. ALL AVAILABLE PATIENT INFORMATION WAS INCLUDED. ADDITIONAL PATIENT DETAILS ARE NOT AVAILABLE.
