The Medical Device Coordination Group (MDCG) has published revision 5 of its guidance on the IVDR classification rules (Regulation (EU) 2017/746, Annex VIII). It supports manufacturers, notified bodies and health institutions in assigning the correct risk class (A–D) before an IVD is placed on the market.
Per the revision table, rev.5 is limited to rule 7. Rule 7 concerns controls without a quantitative or qualitative assigned value. These fall under risk class B. The rationale was clarified and the examples revised.
Key points to consider:
- Standalone quality control (QC) materials are needed to monitor the validity of laboratory examination procedures; the IFU should clearly specify this intended purpose and that standalone QC materials do not replace the QC required to verify IVD performance.
- Indicative value ranges stated by the manufacturer in the IFU (presence or concentration range of the analyte) are not “assigned values”; such standalone QC materials remain class B.
- Diagnostic-related controls with assigned quantitative or qualitative values follow implementing rule 1.6.
