Agilent Technologies Denmark ApS Brand Name: FLEX Monoclonal Mouse Anti-Human CD20cy recall: Their is the potential for weak staining which may result in false negative

Recall published 1+ years ago

Their is the potential for weak staining which may result in false negative CD20 identification.

The hazard: Device malfunction

The notice describes a specific failure mode. That detail is what a clinician needs, because the right action differs sharply between a monitor, an implant and a test kit.

What the notice says: Their is the potential for weak staining which may result in false negative CD20 identification.

Why it matters: The device may not perform as intended — a mechanical failure, a software defect, an inaccurate reading, or an alarm that does not sound. For a device someone depends on, the consequence of the failure is usually worse than the failure itself.

Symptoms and when to call a doctor

If the device supports a vital function, do not disable or remove it on your own judgement. Contact the clinician who prescribed or fitted it, and use the back-up arrangement they gave you. Go to an emergency department if the symptoms the device is meant to manage are getting worse, or if an implanted device gives an unexpected alarm or shock.

This page is general information, not medical advice. If you feel unwell, a clinician who can see you is the only person able to judge your case.
