Siemens Chek-Stix Control Strips Recalled for Potential Leukocyte Result Errors
Siemens Healthcare Diagnostics is recalling specific lots of 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 recall is classified as FDA Class III, which by definition is unlikely to cause adverse health consequences. The issue is a potential inaccuracy in control results rather than a direct patient safety hazard.
