Enzymatic Esterase--Oxidase, Cholesterol（CHH）

The devices were distributed without required FDA premarket clearance or approval.

Product fails to meet the performance claims quoted on the kit insert: Manual Procedure when calibrating using the standard provided in the kit, the change in absorbance is lower than expected generating internal quality control results high outside range; Cholesterol (CHOL) Instrument Specific Application using the recommended calibration material CAL2351, the product fails to meet its linearity performance claim quoted on the kit inserts. The linearity is reduced by up to -35% however Quality Control results will still fall within assigned ranges. This may lead to delayed results.

Cholesterol Reagent may fail with Out of Calibration Range Low (OCR Low) and/or Back to Back (B/B) errors. Low quality control recovery failures may be observed after passing calibration. Brown particulates in compartment C of the reagent cartridge may be observed. Continued use may lead to, 1) failed QC and/or calibrations, 2) Erroneous low Cholesterol patient results.

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

Sterling Diagnostics, Inc. initiated a recall on 7/20/2016 for multiple diagnostic kits due to a recision of the previously extended expiration dates for the kits.

Beckman Coulter has identified that Dipyrone (Metamizole) may cause erroneous, false low results in the following assays: Cholesterol OSR6X16, Triglyceride OSR6X118, Uric Acid OSR6X98, Lactate OSR6X93, and Lipase OSR6X30.

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

N-Acetylcysteine (NAC) present in the blood of patients treated for paracetamol overdose can interfere with the Trinder reaction that uses hydrogen peroxide catalytic on aminoantipyrine and phenol, and can produce falsely low results with the reagents using the Trinder reaction method.

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.

N-Acetyl Cysteine (NAC), when administered in therapeutic concentrations for the treatment of acetaminophen overdose, interferes with the assays for these analytes: Cholesterol OSR6X16, Uric Acid OSR6X98, Lactate OSR6X93, and Lipase OSR6X30. NAC interference may lead to falsely low results.
