Is it a medical device?
You do not need to know whether a product falls under the MDR, IVDR, the EU AI Act or none of them before asking. Working that out is often the first question.
If a product uses AI, blood tests, biomarkers, genetic data, clinical information, symptoms or other health data, relatively small differences in what it does and what is claimed for it can change the regulatory pathway considerably.
Classification & conformity pathwayMy software uses blood-test results. Does that make it an IVD?
Not automatically.
The answer depends on what the software is intended to do with the information, what output it produces and the medical purpose of that output.
Software using laboratory data can potentially fall under IVDR, MDR or outside medical-device regulation depending on its intended purpose and functionality.
Our AI gives personalised health insights. Is it a medical device?
Potentially.
The important question is not simply whether the product uses AI.
Qualification depends on what the software is intended to do and whether its output serves a medical purpose such as diagnosis, prediction, monitoring or treatment.
Can we call ourselves a wellness product?
Sometimes a product can legitimately remain outside medical-device regulation.
But “wellness” is not simply a label.
The functionality, intended purpose, claims, user experience, instructions and marketing all need to support that position.
Can we launch an MVP first and deal with regulation later?
Not if the early version is itself a medical device or IVD. Making a device available on the EU market, whether paid or free and whether called a beta or not, generally requires it to meet the MDR or IVDR first.
What is possible depends on what the early version does and claims. A version without a medical purpose may fall outside the regulations, and clinical investigations and performance studies follow their own rules. Deciding what the first version does is a regulatory decision as well as a product decision.
What risk class is our product?
That follows from the intended purpose and the classification rules in Annex VIII of the MDR or the IVDR. Medical device software is mainly classified under MDR Rule 11; IVDs fall into classes A to D.
The class decides whether a Notified Body is needed and which conformity assessment routes are open, so it is worth establishing before planning around it.
Evidence and validation
How much evidence a product needs depends on what it is for, what is claimed and who it is used on, not on a standard number of studies.
Evidence and validationHow much validation is enough?
There is no universal number of patients, samples or validation studies.
The evidence needs to support the intended purpose, claims, risk, population and technology of the particular product.
Can we use retrospective data?
Sometimes. Retrospective data can contribute to clinical or performance evidence when it is relevant to the intended purpose, of adequate quality and representative of the intended population.
Whether it is enough on its own depends on the claims, the risk and what the data can and cannot show.
Conformity assessment
Whether independent assessment is needed, and what it involves, follows from qualification and classification.
Notified Body readinessDo we need a Notified Body?
That depends on whether your product qualifies as a medical device or IVD and how it is classified.
For many regulated devices, independent conformity assessment is required before CE marking.
The important step is to establish the pathway before planning around assumptions.
