Plain-English summary

The Sensititre MDRGN3F is an in vitro diagnostic device manufactured by Remel Inc used for antibiotic susceptibility testing of gram-negative bacteria.

An internal technical investigation confirmed the device may produce false susceptible results when testing bacteria from the Proteae Tribe (including Proteus species, Providencia species, and Morganella Morganii) against doripenem, ertapenem, meropenem, imipenem, cefepime, piperacillin/tazobactam, and aztreonam. This means organisms resistant to these antibiotics may be reported as susceptible.

The recall affects 70 units distributed nationwide (lot B2311B).

False susceptible results could lead to inappropriate antibiotic treatment selection, potentially compromising patient outcomes.
