Sign in to monitor this recall

Summary

Biomerieux Inc. has recalled over 2.6 million VITEK 2 Gram-negative Susceptibility Cards because they may produce incorrect quality control results or show false antibiotic resistance when testing certain bacteria like Enterobacterales and Pseudomonas aeruginosa. This recall affects a wide range of product models distributed worldwide and nationwide in the U.S. Laboratory professionals use these cards to determine which antibiotics will effectively treat a patient's infection.

Risk

If the test cards provide false resistance results, a patient might be denied an effective antibiotic treatment, or their treatment could be delayed while clinicians investigate the inconsistent results. This defect can also lead to laboratory quality control failures.

See the Affected Products section below for the full list of affected codes.
  2. Check your inventory for all lot codes associated with the identified Gram-negative AST test kits containing Polymyxin B, Ceftazidime/avibactam, Meropenem/Vaborbactam, Imipenem, or Imipenem/Relebactam.
  3. Stop using the recalled product. Contact the manufacturer or your distributor to arrange return, replacement, or correction.
