Thyroglobulin Antibody Assay Instructions Incorrectly State Biotin Interference Resolution
Beckman Coulter is recalling over 465,000 thyroglobulin antibody test kits because their instructions incorrectly state that biotin interference was addressed. The false information could lead to false-low test results.
What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: This is a labeling error that creates risk of patient harm. Instructions incorrectly state that biotin interference was remediated, which could result in false-low test results and affect clinical decision-making for thyroid cancer patients. No illnesses or injuries have been reported, placing this at the High severity level per the rubric criterion for risk-of-harm products where injury has not yet been reported.
