Medical Translation Services: ISO Quality Guide
Every translation company says it cares about quality. Few can show you how. In healthcare, where an unclear sentence can have real consequences, “trust us” isn’t a great standard. That’s where ISO certifications come in. They’re independent proof that a provider follows documented, audited processes. When you’re choosing medical translation services, understanding what each certification actually means helps you separate genuine quality systems from marketing language. Let’s break down the main standards and what they should mean for your project.
ISO 17100: the translation-specific standard
ISO 17100 is written specifically for translation services. It sets out requirements for the core process, including the competence of translators, project management, and review. One of its defining features is that translated work must be checked by a second qualified linguist rather than simply sent out after a single pass.
Ulatus is certified to ISO 17100:2015. For a medical buyer, this is the baseline. It says the provider has defined how translators are selected, how work is revised, and how records are kept. If a company can’t confirm this one, it’s worth asking why.
ISO 13485: built for the medical device world
ISO 13485 deals with quality management systems for organizations in the medical device sector. Many device manufacturers hold it themselves, and they often prefer suppliers who understand that kind of environment. Ulatus holds ISO 13485:2016.
It’s worth being clear about what this does and doesn’t mean. The certificate applies to the provider’s quality system, not to individual documents. But a company that operates under this standard is used to controlled documents, traceability, and corrective actions, which is just what you want when translating labels, manuals, and technical files.
ISO 9001 and ISO/IEC 27001: the supporting pillars
ISO 9001:2015 is the broader quality management standard. It focuses on consistent processes, customer focus, and continuous improvement. For you, that translates into predictable delivery and a structured way of handling feedback or complaints.
ISO/IEC 27001:2022 covers information security management. Medical content often includes unpublished research, patient-related details, and proprietary product data. A security standard shows that the provider has assessed risks and put controls around how files are stored, shared, and accessed. In an industry where leaks can be costly, it’s a major point in a provider’s favor.
How to check what a vendor actually holds
Certifications are easy to claim and just as easy to blur. Ask for the certificate, check the scope and the date, and confirm which standards the company holds rather than which it “follows” or “aligns with.” Those two phrases aren’t the same.
Then go a step further and ask how the standards show up in daily work. Who revises the translation? How are terminology decisions recorded? What happens when a client reports an error? A provider that’s genuinely certified will answer these questions without hesitation, because the answers are part of their routine.
Certification isn’t the whole story
Even so, a certificate doesn’t write a good sentence. You still want to know about the linguists doing the work. Ulatus works with more than 250 life science linguists across over 40 therapeutic areas, and each goes through a recruitment process that validates qualifications before projects are assigned. The standards provide the framework, and the people fill it in.
Look, too, at track record. Case studies, client feedback, and examples of comparable projects tell you how a provider performs when the schedule is tight and the material is complicated. The best combination is certified process plus demonstrated experience.
Final thoughts
ISO standards won’t guarantee perfection, but they raise the floor and make quality measurable. When you’re evaluating options, check the certificates, ask how they shape the workflow, and look for evidence in past projects.
