What is a Notice of Concern

A notice of concern may be issued by WHO after an inspection was performed at a site where observations were made that result in concern regarding compliance of the site with specified standards such as ISO 13485:2003 (Medical devices - Quality management systems).

A notice of concern may also be issued if the requested response to the observations noted in an inspection report, detailing the corrective actions taken or proposed to be taken, is not received by WHO on or before the due date (i.e. 90 days from the date when final inspection report sent).

A notice of concern will remain active on the WHO Prequalification of Diagnostics Programme web site until WHO is satisfied that the corrective actions taken are appropriate and have been effectively implemented.
