Siemens Chek-Stix Control Strips Recalled for Potential Leukocyte Result Errors

Siemens Healthcare Diagnostics is recalling Chek-Stix control strips because the leukocyte result may become negative if the solution is held above 25°C for more than two hours.

What this means for you

Cosmetic or documentation issue. No expected health impact, but the manufacturer is correcting the affected products.

Our severity reasoning: The agency classification is Class III, which the rubric defines as typically resulting in a score of 1 or 2 because it is unlikely to cause adverse health consequences. The issue is a potential error in a control strip result under specific storage conditions, not a direct patient safety hazard.
