    • Terminated Z-1174-2012 FDA Unclassified (pre-2012) initiated 11 Aug 2009 on shared 510(k) K955644

    The recall was initiated because Beckman Coulter has confirmed reports of variability in results with the lots of Phenobarbital (PHE) reagent and calibrator.

    • Terminated Z-2437-2010 FDA Unclassified (pre-2012) initiated 19 Feb 2009 on shared 510(k) K955644

    The reagent produces false low test results. Beckman Coulter has confirmed low recovery of values at the low end of the therapeutic range (<1.5 ug/mL, <3.13 umol/L) with SYNCHRON Systems Gentamicin Reagent (GEN) lot M804552. A false low result can cause a patient to receive more medication than necessary.

    Product was found to produce higher recoveries by about 7-12% compared to other lots.
