Multiple Lot Numbers affected

ARTG Number: 187139
Recall Action Level Hospital
Recall Action Classification Class I
Recall Action Commencement Date 2/12/2015
Responsible Entity Biomerieux Australia Pty Ltd
Reason/Issue It has been identified that isolates (Enterobacteria strains) were tested with agar dilution and broth micro dilution reference method:
Using EUCAST breakpoints (MIC< or =8: Susceptible ; MIC>16: Resistant), Etest PIP/TAZO showed a higher frequency of erroneous results, false susceptible results, when comparing to the referenced method (Broth-Micro Dilution).

The risk to patients as a result of the performance shift is the potential for reporting erroneous results for Piperacillin/Tazobactam; specifically false susceptible results. This risk may lead to medical intervention for the patient because the erroneous result could negatively influence the selection of antibiotic therapy.
