    DIASORIN MOLECULAR LLC RECEIVED A COMPLAINT ALLEGING FALSE POSITIVE RESULTS ON AN UNKNOWN NUMBER OF PATIENT SAMPLES THAT RESULTED POSITIVE WHEN USING THE SIMPLEXA COVID-19 DIRECT ASSAY, BUT NEGATIVE ON COMPETITOR ASSAYS (SEEGENE, CEPHEID GENEXPERT). RUN FILES FROM THE SIMPLEXA ASSAY WERE NOT PROVIDED FOR ANALYSIS. THE CUSTOMER'S DEVICE AND SUSPECTED FALSE POSITIVE SAMPLES WERE NOT PROVIDED FOR INVESTIGATION. IT IS KNOWN THE SEEGENE TARGETS (E GENE, RDRP, N GENE) AND GENEXPERT TARGETS (E GENE, N2 GENE) ARE DIFFERENT THAN THE SIMPLEXA TARGETS (S GENE, ORF1AB). THE CUSTOMER'S DEVICE AND SUSPECTED FALSE POSITIVE SAMPLES WERE NOT PROVIDED FOR INVESTIGATION. PATIENT SYMPTOM INFORMATION WAS NOT PROVIDED. A DIASORIN SUBSIDIARY WAS TROUBLESHOOTING WITH THE CUSTOMER AND OBSERVED THAT THE CUSTOMER'S DAD DISCS MAY HAVE BEEN CONTAMINATED AT THE SITE (POSSIBLY BY GLOVES). ONCE THE DISCS WERE REPLACED, NO FURTHER FALSE POSITIVES OCCURRED. THE ISSUE IS NOT CONFIRMED. BATCH RECORD REVIEW SHOWED THE CRITICAL COMPONENT, REACTION MIX MOL4151, LOT# X8156N, MET ALL QC RELEASE CRITERIA PRIOR TO KIT RELEASE. A TOTAL OF (B)(4) NO-TEMPLATE CONTROL (NTC) REPLICATES WERE RUN AND RESULTED IN ZERO (0) OCCURRENCES OF FALSE POSITIVES IN EITHER S GENE OR ORF1AB TARGETS. NO MALFUNCTIONS OCCURRED DURING QC RELEASE TESTING. THIS IS THE 1ST COMPLAINT ON MOL4150, LOT# X8165N FOR SUSPECTED FALSE POSITIVE RESULTS.
