The new section in the guidance consists of the following points:

  • An IVD requiring a new UK performance evaluation study should be registered by the time the study commences, and no grace period will be applied.
  • For existing ongoing performance evaluations that began before December 31, 2020, the grace period provided in the guidance for the type of IVD (List A, List B, or general) remains applicable.
  • A UK Responsible Person or Northern Ireland-based Authorized Representative must be appointed by non-UK manufacturers conducting a performance evaluation in the UK in order to register with the MHRA.​
