    US CUSTOMER CONTACTED CEPHEID TO DISCUSS PATIENT RESULTS FOR XPERT XPRESS SARS-COV-2. CUSTOMER COLLECTED SAMPLE 1 FROM PATIENT-1 ON (B)(6) 2021, WHICH WAS TESTED ON XPERT XPRESS SARS-COV-2 AND RESULTED AS SARS-COV-2 POSITIVE (NOT REPORTED TO THE PHYSICIAN). SAMPLE 1 REPEAT-1 OCCURRED ON (B)(6) 2021 AND TESTED ON XPERT XPRESS SARS-COV-2/FLU/RSV, WHICH RESULTED IN SARS-COV-2 NEGATIVE, FLUA NEGATIVE, FLUB NEGATIVE RSV POSITIVE (NOT REPORTED TO THE PHYSICIAN). SAMPLE 1 REPEAT-2 OCCURRED ON (B)(6) 2021 AND TESTED ON XPERT XPRESS SARS-COV-2/FLU/RSV, WHICH RESULTED IN SARS-COV-2 NEGATIVE, FLUA NEGATIVE, FLUB NEGATIVE RSV POSITIVE (NOT REPORTED TO THE PHYSICIAN). SAMPLE 1 REPEAT-3 OCCURRED ON (B)(6) 2021 AND TESTED ON XPERT XPRESS SARS-COV-2, WHICH RESULTED IN SARS-COV-2 NEGATIVE (REPORTED TO THE PHYSICIAN). FOR 4PLEX, LIKELY ROOT CAUSE IS COMPETITIVE INTERFERENCE BETWEEN RSV AND SARS-COV-2 (FN SARS2). FOR SARS STANDALONE, THE LIKELY ROOT CAUSE IS TARGET NEAR THE LOD OF THE ASSAY. THERE IS NO EVIDENCE OF PRODUCT MALFUNCTION AND THERE WAS NO REPORTED HARM. FALSE POSITIVE RESULTS FOR SARS-COV-2 COULD LEAD TO INCORRECT MANAGEMENT OF SYMPTOMATIC PATIENTS, INCLUDING UNNECESSARY ISOLATION OR QUARANTINE, MISALLOCATION OF RESOURCES, DELAYED DIAGNOSIS AND TREATMENT FOR OTHER INFECTIONS OR HEALTH CONDITIONS, OR UNNECESSARY ANTIVIRAL TREATMENT. CEPHEID'S PATIENT SAFETY BOARD CONSULT CONFIRMED WITH THE CUSTOMER THAT THERE WAS NO ASSOCIATED PATIENT HARM OR CHANGE TO PATIENT TREATMENT. AS PER SECTION 3 OF XPERT XPRESS SARS-COV-2 EUA IFU; POSITIVE RESULTS ARE INDICATIVE OF THE PRESENCE OF SARS-COV-2; CLINICAL CORRELATION WITH PATIENT HISTORY AND OTHER DIAGNOSTIC INFORMATION IS NECESSARY TO DETERMINE PATIENT INFECTION STATUS. NOTE FOR SECTION DEVICE EVALUATED BY MANUFACTURER - ANSWER OF NO IS DUE TO THE SINGLE USE OF THE XPERT XPRESS SARS-COV-2 TEST AND THE UNAVAILABILITY OF THAT PRODUCT LOT TO BE RETURNED TO CEPHEID.
