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 recall involving a diagnostic test for a serious infectious disease where storage failure presents risk of test failure and potential missed diagnoses. No illnesses or injuries have been reported, meeting the criterion for 'risk-of-harm products where injury has not yet been reported.'

Plain-English summary
