Why IVDs need their own map
In vitro diagnostics share much with medical devices, including ISO 13485 quality systems, but the EU regulates them under a separate regulation with its own classes and deadlines. In 2026 the EU IVDR is where most of the pressure sits, and Japan and the US cover IVDs inside their broader frameworks.
The IVD regulatory map at a glance

| Core law | IVDR 2017/746 | FD&C Act and 21 CFR device rules | PMD Act | IMDRF (IVD classification among tracked topics) |
| Quality system | IVDR Article 10(8) QMS and harmonised ISO 13485 | QMSR, 21 CFR 820 | QMS Ordinance (MO169), which covers medical devices and IVD reagents | ISO 13485 |
| Risk management | IVDR Annex I | QMSR | QMS Ordinance | ISO 14971 |
| Classification and interpretation | MDCG guidance, including MDCG 2020-16 rev.5 | FDA guidance | PMDA guidelines | IMDRF documents |

The IVDR deadline calendar
Regulation (EU) 2024/1860 extended the IVDR transition for legacy devices, on conditions: continued compliance with the old directive, no significant change in design or intended purpose, and an IVDR QMS by 26 May 2025.
| IVDR class | Apply to notified body by | Written NB agreement by | Legacy deadline |
|---|---|---|---|
| Class D | 26 May 2025 | 26 September 2025 | 31 December 2027 |
| Class C | 26 May 2026 | 26 September 2026 | 31 December 2028 |
| Class B and class A sterile | 26 May 2027 | 26 September 2027 | 31 December 2029 |
As of late October 2026, the class C agreement milestone has just passed, and class B and A sterile manufacturers have about seven months to apply.
Other 2026 changes for IVD makers
- MDCG 2020-16 rev.5 on IVDR classification rules (September 2026).
- EUDAMED: four modules mandatory since 28 May 2026; MDCG 2026-4 covers summaries of safety and performance in EUDAMED.
- US QMSR effective 2 February 2026, with ISO 13485:2016 incorporated by reference.
- EU simplification proposal (16 December 2025) would amend the IVDR too, but is not yet law.

Building an IVD knowledge base
- Make the IVDR, with CELEX and consolidation date, the EU core.
- Build the deadline table from Regulation 2024/1860 and tag each product by class.
- Add MDCG 2020-16 rev.5 and archive rev.4.
- Store the 2025 proposal separately as “proposed.”
- Use your own QMS documents and ISO clause numbers instead of ISO text.
- Set reminders for 26 May 2027 and 26 September 2027 (class B and A sterile).
