Recalls for Nad Reduction/nadh Oxidation, Lactate Dehydrogenase

Pointe Scientific Lactate Dehydrogenase (Liquid) Reagent Set stability claim is not being met.

Possible drug interference when using the Trinder reaction method on multiple Cobas Analyzers. Results of Trinder tests may be falsely decreased when the tests are run with urine samples (Creatinine plus and Uric Acid applications only) or blood samples collected before sufficient time has lapsed after the administration of the drugs Acetaminophen and N-acetylcysteine.

Ortho Clinical Diagnostics is recalling Slide Dispense cartridges used with some VITROS Chemistry Product Slides due to slide dispense issues.

Siemens Healthcare Diagnostics has confirmed that Dimension Vista Lactate Dehydrogenase (LDI) may exhibit an erroneously elevated result when the preceding assay in the reaction cuvette is Lactic Acid (LA). The magnitude of the elevation may be variable. Both quality control and patient samples may be impacted. Incomplete removal of residual lactate dehydrogenase, a component of the LA reagent, has been identified as the cause of the potentially elevated result. A falsely elevated result for lactate dehydrogenase may lead to additional investigations to determine the etiology of tissue damage. Results would be correlated with clinical history and presentation in addition to other diagnostic laboratory testing.

Siemens Healthcare Diagnostics has become aware of N-Acetylcysteine (NAC) and Metamizole (Dipyrone) interference with Trinder and Trinder-like reaction assays. Siemens has confirmed that falsely depressed results may occur on samples drawn from patients receiving N-Acetylcysteine (NAC) or Metamizole. NAC is the accepted antidote for acetaminophen toxicity and is justified in patients at signific

Beckman Coulter has identified the following drugs as potential sources of interference: Metamizole (Dipyrone), Sulfasalazine, and Sulfapyridine and may result in false low results.

An update to the carryover avoidance technical bulletin to introduce additional steps for reagent carryover avoidance with the Lactate Dehydrogenase assay on RX Instruments. Additional pipette washes can be implemented as described in the technical bulletin. Interference to the Lactate Dehydrogenase (LOH) reagent would be observed as inconsistencies in Quality Control recovery, which may lead to a delay in running patient samples, or erroneous elevated test results.
