    (B)(6). THE CUSTOMER DID NOT SUPPLY PATIENT DEMOGRAPHICS SUCH AS AGE, DATE OF BIRTH, SEX, WEIGHT, ETHNICITY OR RACE. THE ACCESS SARS-COV-2 IGG REAGENT WAS NOT RETURNED FOR EVALUATION. NO ERROR MESSAGES OR ISSUES WITH OTHER ASSAYS WERE REPORTED. AVAILABLE SYSTEM PERFORMANCE INDICATORS OF PASSING CALIBRATION AND QUALITY CONTROL RECOVERY DID NOT DEMONSTRATE AN ISSUE WITH THE SYSTEM. THERE WERE NO REPORTS OF HARDWARE INTERVENTIONS PERFORMED OR HARDWARE PARTS REPLACED. ¿ SARS-COV-2 IS AN ENVELOPED NON-SEGMENTED POSITIVE-SENSE RNA VIRUS. IT HAS SEVERAL STRUCTURAL PROTEINS INCLUDING SPIKE (S), ENVELOPE (E), MEMBRANE (M) AND NUCLEOCAPSID (N). THE SPIKE PROTEIN (S) CONTAINS A RECEPTOR BINDING DOMAIN (RBD) WHICH IS RESPONSIBLE FOR RECOGNIZING THE CELL SURFACE RECEPTOR, ANGIOTENSIN CONVERTING ENZYME-2 (ACE2). IT IS FOUND THAT THE RBD OF THE SARS-COV-2 S PROTEIN STRONGLY INTERACTS WITH THE HUMAN ACE2 RECEPTOR LEADING TO ENDOCYTOSIS INTO THE HOST CELLS AND VIRAL REPLICATION. THE ACCESS ASSAY DETECT ANTIBODIES DIRECTED AGAINST THE SPIKE PROTEIN, WHICH ARE MORE LIKELY TO NEUTRALIZE THE VIRUS. ¿THE LOCAL SUPPORT ORGANIZATION EXPLAINED DIFFERENCES BETWEEN ASSAYS TARGETING NUCLEOPROTEIN AND ASSAYS TARGETING SPIKE PROTEIN. ¿VALUES OBTAINED WITH DIFFERENT ASSAY METHODS SHOULD NOT BE USED INTERCHANGEABLY AND DIFFERENCES BETWEEN METHODS ARE EXPECTED. IN CONCLUSION, THE CAUSE OF THIS EVENT CANNOT BE DETERMINED WITH THE AVAILABLE INFORMATION. THERE IS NO EVIDENCE TO REASONABLY SUGGEST THAT A REAGENT OR HARDWARE MALFUNCTION OCCURRED IN THIS EVENT.

THE LOCAL SUPPORT ORGANIZATION EXPLAINED DIFFERENCES BETWEEN ASSAYS TARGETING NUCLEOPROTEIN AND ASSAYS TARGETING SPIKE PROTEIN. TWO (2) MEDWATCH REPORTS WILL BE GENERATED TO ADDRESS CUSTOMER REPORTS OF NON-REACTIVE SARS-COV-2 IGG PATIENTS RESULTS OBTAINED AT TWO DIFFERENT DATES. MEDWATCH NUMBER ¿2122870-2021-00099¿ WILL ADDRESS PATIENT FOUR (4) RESULT OBTAINED ON (B)(6) 2021.
