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: FDA Class II medical device recall with no reported injuries or illnesses. The product defect (leakage in amplification discs causing contamination and invalid test results) qualifies as a risk-of-harm product where injury has not yet been reported.
