    Additional Manufacturer Narrative · 1

    THE CUSTOMER USED UP ALL OF THE REAGENT AND HAD NOTHING TO RETURN. THE INVESTIGATION OF THE SIMPLEXA FLU A/B RSV DIRECT KIT (MOL2650) SUGGESTED THAT THE ROOT CAUSE FOR THE OCCURRENCE OF FALSE POSITIVE (AND SUB-AMPLIFICATIONS) WERE DUE TO THE LOT TO LOT VARIABILITY OF THE SCORPION PRIMERS. TO MITIGATE THE OCCURRENCE OF FALSE POSITIVES (AND SUB-AMPLIFICATIONS), FOCUS DX REPLACED THE RECOMBINANT TAQ POLYMERASE USED IN THE MOL2651 REACTION MIX WITH HOT-START TAQ POLYMERASE AND REDUCED PRODUCTION TIME FOLLOWING BULK MOL2651 FORMULATION TO 2 HOURS. ADDITIONALLY, FOCUS DX NOW EMPLOYS MORE EXTENSIVE TESTING WITH NO TEMPLATE CONTROL (NTC) IN THE QA KIT RELEASE CRITERIA. THESE CORRECTIVE AND PREVENTATIVE ACTIONS ARE EFFECTIVE IN MITIGATING THE EFFECTS POSED BY THE POTENTIAL LOT TO LOT VARIABILITY OF THE SCORPIONS. (B)(4).
