Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR) has been in full application since May 2022, with extended transition deadlines for certain devices running to 2027. For manufacturers placing diagnostic tests, reagents or analytical instruments on the European market, that means labels, instructions for use (IFU) and technical documentation in every official language of each Member State where the device is sold. A mistranslated reference value or calibration instruction is not a linguistic detail. It is a diagnostic risk.
What the IVDR requires in language terms
Article 10 and Annex I of the IVDR state that information supplied with a device, including labelling and instructions for use, must be available in the language or languages required by the Member State where the device is made available. This covers:
- Primary and secondary packaging labels
- Instructions for use (IFU)
- Summary of safety and performance (SSP), mandatory for Class C and D devices
- Technical documentation submitted to the notified body
- EU declaration of conformity
- User training material, where applicable
Each country sets its own national language requirements. Portugal, Spain, France and Germany all require translation into the national language for devices made available to healthcare professionals and the public. A manufacturer selling the same diagnostic test across six European markets may need six language versions of the IFU, each aligned to the same underlying technical file.
Terminology that leaves no room for ambiguity
IVD translation deals with terms where one wrong choice changes the clinical outcome. Some examples:
| English term | Common mistranslation risk | Why it matters |
|---|---|---|
| Analytical sensitivity | Confused with clinical sensitivity | Different statistical meaning, different risk profile |
| Cut-off value | Rendered inconsistently across documents | Determines how the result is interpreted |
| Cross-reactivity | Omitted or softened | Affects interpretation of false positives |
| Intended purpose | Translated loosely instead of using the fixed regulatory term | Must match wording used across the technical file |
| Performance evaluation | Confused with "clinical evaluation" (an MDR term) | Wrong regulatory framework implied |
Terminology consistency between the IFU, the label and the summary of safety and performance is checked by notified bodies. Discrepancies between documents for the same device trigger requests for clarification and delay certification.
Risk class determines how much translation rigour is needed
The IVDR classifies devices into four risk classes (A, B, C, D) based on risk to the patient and to public health. A home-use glucose test (Class B or C) has different requirements from an HIV or hepatitis detection test (Class D), which requires notified body assessment and a mandatory summary of safety and performance.
The higher the risk class, the more scrutiny the translation deserves. For Class C and D devices, supporting clinical documentation shares terminology with clinical trial protocols, and it is worth applying the same rigour described in our article on translating clinical trial protocols for regulatory submission. Manufacturers who also market general medical devices (non-IVD) should factor in the parallel requirements of the MDR, covered in detail in medical device documentation translation under MDR.
How to structure the translation project to reduce risk
A manufacturer planning entry into several European markets saves time by preparing the translation project alongside the notified body submission, not after it. Practical points to fix upfront:
- Agree a bilingual terminology glossary before translation starts, validated by whoever signs off the technical file
- Use a single translation memory across the IFU, label and SSP for the same device, to keep terminology consistent between documents
- Build in time for the regulatory review cycle, since post-approval changes from the notified body typically require re-translation of specific sections
- Confirm whether the destination market accepts multilingual labelling or requires country-specific packaging
IVD documentation falls into the category of high-impact content where an error carries a direct clinical consequence. For this type of project, M21Global recommends the Estratégica tier, with translation, review by a second linguist and quality control within the ISO 17100 audited workflow, suited to IFUs, labels and summaries of safety and performance submitted to a notified body.
Working with a partner that understands the IVDR
M21Global brings over 20 years of experience in technical and regulatory translation, with ISO 17100:2015 certification audited by Bureau Veritas and more than 445 million words translated to date. The team works regularly with in vitro diagnostic terminology, pharmaceutical labelling and clinical documentation, including the requirements covered in our article on drug labelling translation and on the pharmaceutical translation service page.

Frequently Asked Questions
Does the IVDR require translation into every EU language?
Not automatically into all of them: each Member State sets its own national language requirements for labelling and instructions for use, so the translation needed depends on which markets the device is actually made available in.
Which IVD device documents need translation?
Typically the label, instructions for use (IFU), summary of safety and performance (for Class C and D devices), and the relevant sections of the technical documentation submitted to the notified body.
What is the difference between translating for IVDR versus MDR?
IVDR applies specifically to in vitro diagnostic devices, with its own terminology such as analytical sensitivity and cross-reactivity, while MDR covers general medical devices with distinct clinical evaluation requirements.
How long does IVD documentation translation take?
Timelines depend on volume, number of target languages and the device's risk class; M21Global provides a quote with an estimated timeline within three business hours of your request.
