[12657055]
The testing detected the presence of flu a, flu b, and rsv analytes in the positive control. The customer's samples were all flu b negative. The data indicated that the component mol 2651 was most likely the cause of the aberrant flu b signals observed by the customer. 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. Mfr ref #:(b)(4).
