Subject: IVD product classification according to IVDR 2017/746
Dear Evangelos,
Is this a new product or is it already on the market?
The intended use statements 1) and 2) only explain the test principle. Given that the analysis takes place after sampling, IVDR, not MDR is the applicable legislation. Please note that IVDR is also quite explicit regarding the Intended purpose, see Annex I paragraph 20.4.1 (c) "the device's intended purpose:"
For the proper classification of your devices you need to describe who the users of these products are, and the clinical context in which these products are used (aka what do users do with the information provided by the test). Risk management file is also a vital source of information: the devices you describe test pathogenic microorganisms, so from the patient and public health perspective: what are the consequences of the false positive or false negative result?
Will they receive an ineffective treatment? Can they infect others?
I know that nowadays company management may pressure it QA/RA specialists to try every trick in the book to end in Class A, which the only one that does not require Notified body approval, but this must be justified beyond doubt. In this case, if the tests are for characterization of infectious pathogens, Class B is seems the most appropriate choice.
Kind regards,
Agnieszka

Hello Richards
Thank you so much for your quick contribution and feedback.
So then you maybe ask the question: is this an IVD medical device? Or could it just be classified as a laboratory test? With the regulations now, it is definitely important to think about the intended use and also the intended purposes of devices to maybe document the rationale for the classification chosen
I have not addressed the question of whether these products are IVD/laboratory tests? at all and thank you for it, I will deal with it in the company.
Kind regards

Hello Evangelos,
Unfortunately I think you are look at Class B just from the fact if products do not fall in Class D, C, or A, then it all defaults to Class B. Personally, I still do not like the classification methodology for IVDs (even the one described in GHTF) because there are many layers of risk stratification for IVD products where by "default" many of them end up in this moderate-to-low category. Then compounding this with the EU MDR, this means all Class B products (and C, D) require Notified Body intervention. This is the difficult now with the EU IVDR having this 80/20 split where now 80% of IVDs will require NB intervention.
To further, with understanding only seeing the intended use statement for these products, I would not say they are Class A under Rule 5 particularly under the instrument definition. For me personally, those instruments are items like centrifuges, heating plates, sediment, other "processing" type instruments. The two tests you are describing still provide a result such as susceptibility and differentiation of organisms. When reading definitions for Class A, do not really see them falling in there so by default Class B. Now with that said, personally I would think tests like these should be low risk and not moderate-to-low risk because maybe being used for testing purposes were the results are not specifically related to provide results to a patient. So then you maybe ask the question: is this an IVD medical device? Or could it just be classified as a laboratory test? With the regulations now, it is definitely important to think about the intended use and also the intended purposes of devices to maybe document the rationale for the classification chosen. In your examples, maybe could write a rationale for how these are Class A because they are instruments testing organisms, but more importantly examining how these interact with the patient specimen, i.e. just used for processing or a step in the analysis.

Subject: IVD product classification according to IVDR 2017/746
Hi RAPS
IVD product - classification .MDR 2017/746
I would like to ask you for feedback if our classification is correct and the product falls into class A acc. to Annex VIII -IVDR 2017/746
Here is define intended purpose for both IVD producs:
1)Antimycotic susceptibility discs are used for the determination of the susceptibility of microscopic fungi to antimycotic agents in vitro. It is possible to get the information about actual susceptibility of the tested fungal isolate by a simple diffusion method after 18-24 hrs already.
The results of the antimycotic antibiogram make it possible to start a rational treatment of the mycotic infection.
2)OPTOCHIN diagnostic discs are used for simple presumptive differentiation of Streptococcus pneumoniae from other viridans streptococci.
Note: Products detect infection, not life-threatening disease
As a first step, we have started to comply with Annex VIII, i.e. the classification rules.
According to Annex VIII we classified those products in the Class A -Rule 5, as instrument
2.5. Rule 5
The following devices are classified as class A
(a)
|
products for general laboratory use, accessories which possess no critical characteristics, buffer solutions, washing solutions, and general culture media and histological stains, intended by the manufacturer to make them suitable for in vitro diagnostic procedures relating to a specific examination;
|
(b)
|
instruments intended by the manufacturer specifically to be used for in vitro diagnostic procedures;
|
(c)
|
specimen receptacles.
|
We chose this purpose from Article 2 Definition:
"Physiological or pathological process or state " because these products help to determine a specific treatment, ie the patient's state
note:
We also went through all the other rules, however, none of them matched the definition of the intended purpose of use of these 2 types of IVD.
Thanks
Evangelos
