Plain-English summary
Siemens Healthcare Diagnostics, Inc. is recalling Advia Chemistry Assays, specifically the Cholesterol_2 concentrated and Cholesterol, LDL Cholesterol products. The recall involves 137,422 units distributed nationwide across all 50 states, Washington D.C., and U.S. territories.
The recall was initiated because Siemens confirmed that N-Acetylcysteine (NAC) and Metamizole (Dipyrone) interfere with Trinder and Trinder-like reaction assays. This interference may result in falsely depressed test results for patients receiving these medications. NAC is the accepted antidote for acetaminophen toxicity.
Healthcare facilities and laboratories should stop using the affected products and contact Siemens Healthcare Diagnostics for instructions on how to return or dispose of the inventory.
