Why Most Self-Certified IVDs Must Comply with the EU IVDR Right Now


The new European In Vitro Diagnostic Regulation (IVDR 2017/746) went into effect on May 26, 2022. At that time, 80-90% of all IVD manufacturers will have been reclassified to Class B or higher and therefore required an audit by a European Notified Body approved to conduct audits for IVDR compliance (see current list).

While manufacturers of List A and B devices under the In Vitro Diagnostics Directive (IVDD 98/79/EC) are accustomed to the rigors of a Notified Body audit, they are currently very much in the minority. Only 10-20% of all IVDs are subjected to Notified Body audits under the IVDD –  the rest are “self-certified.” This means the manufacturer can self-declare their compliance with certain basic aspects of the regulation and prepare a CE Declaration of Conformity that happily rides along with EU shipments.

So, if you are a manufacturer only making IVDs that are currently self-certified, brace yourself.

Chances Are (Very) High That You Need to Comply with the Full Force of the IVD Regulation in Effect as of May 2022

Many IVD manufacturers have heard about the IVDR grace period, which occurs between May 26, 2022 and May 26, 2024. IVDs with existing valid Notified Body-issued CE certificates (List A, List B, and self-test IVDs used by “lay persons in the home environment”) may continue to sell those devices (if unchanged) until May 2024 or until their certificate expires, whichever occurs first. The problem is that 80-90% of IVDs will not qualify for this “grace period” because they are self-certified under the IVDD and are being up-classified to Class B, C, or D, thus requiring full IVDR compliance.

The only products that will qualify as Class A under the IVDR are things like buffer and washing solutions, products for general lab use, instruments used for IVD procedures, and specimen receptacles. The table below explains the classification shift between the IVDD and IVDR.


IVDD 98/79/EC Classification – Expiring May 25, 2022

General IVDs
Low Risk

Self-Test IVDs
Low/Moderate Risk

List A
Moderate/High Risk

List B
High Risk

Some general IVDs will become Class A under the IVDR and can be self-certified. Most will become Class B or higher.

Many self-test IVDs will become Class C devices under the IVDR and require certification by May 2022.

May be sold until May 2024 or when the existing  IVDD certificate expires, whichever comes first. List A and B devices under the IVDD generally become Class C or D devices under the IVDR.


IVDR 2017/746 Classification – Effective May 26, 2022

Class A
Low Risk

Class B
Low/Moderate Risk

Class C
Moderate/High Risk

Class D
High Risk

Most can be self-certified. If sold sterile, it must be IVDR-compliant by May 2022.

Your IVDD Declaration of Conformity Is Not the Same as a CE Certificate

Because most IVDs have never required CE certification by a Notified Body, some people confuse the CE Declaration of Conformity (DoC) with an actual CE certificate. Under the IVDD, pretty much all General IVDs simply required manufacturers to “self-declare” their conformity with the requirements of the IVD Directive. However, the IVD Regulation requires most manufacturers to go through a Notified Body audit and obtain a CE certificate proving (not self-declaring) their conformity with the IVDR. Under the IVDR, a DoC is still required but means nothing without a corresponding CE certificate. Only Class A devices will not be required to have a Notified Body-issued CE Marking certificate.

All IVD Manufacturers Still Need to Comply with These Areas of the European IVD Regulation

Regardless of whether you manufacture Class A specimen receptacles or hold a valid IVDD certificate that doesn’t expire until 2023, you’ll be required to comply with certain aspects of the 2022 IVD regulation as outlined in Article 110(3):

“By way of derogation from Article 5 of this Regulation, a device with a certificate that was issued in accordance with Directive 98/79/EC and which is valid by virtue of paragraph 2 of this Article may only be placed on the market or put into service provided that from the date of application of this Regulation it continues to comply with that Directive, and provided there are no significant changes in the design and intended purpose. However, the requirements of this Regulation relating to post-market surveillance, market surveillance, vigilance, registration of economic operators and of devices shall apply and replace the corresponding requirements in that Directive.”  (Emphasis added)

See Chapter VII of the IVDR for the surveillance requirements, and Chapter II for more on Economic Operators. Pay special attention to Article 13, a new requirement that applies to all manufacturers.

If your IVD falls into Class B, C, or D, you’ll likely be seeking ISO 13485 certification as a means of complying with the quality system requirements of the IVDR. Get in touch with a Notified Body right away as considerable lead time is required.
