Inside a Regulated Translation Review: English to Kazakh for a Medical Device Manufacturer
English → Kazakh · Client: Confidential (Medical Device Manufacturer)
When a translation touches patient safety, "good enough" isn’t a standard we work with. It’s binary: either every instruction, warning, and technical claim survives the move into the target language intact - or it doesn’t. This is a look inside one such project: the translation and quality review of Instructions for Use (IFU) documentation for a medical device product line, from English into Kazakh, for a manufacturer in the infection-control and disinfection space. The source material was a set of IFU documents for a disinfection product range used in a hospital ENT (otorhinolaryngology) department - cleaning foams, a chlorine-dioxide-based disinfectant, and single-use wipes, all sold as a combination kit. The documentation covered intended use, chemistry and performance data, traceability requirements, pre-use safety checks, and step-by-step application instructions. Content like this sits at the intersection of two things that leave zero room for drift: regulatory language and procedural instruction. A translator can be fluent and still introduce risk if a warning becomes ambiguous or a step loses its sequence.
Challenges & How We Addressed Them
Source-to-Target Parallel Review
Every English segment checked line-by-line against its Kazakh counterpart, section by section - intended use, chemistry, performance claims, traceability, safety checks, and the numbered application steps.
A Formal Deviation Log
Every discrepancy, however minor, gets recorded with a description and a judgment call on materiality - does it change meaning, or is it stylistic?
In-Country Linguist Review
The review was carried out by our senior Kazakh-language linguist, working independently from the original translator, to catch what a second-pass proofread by the same person often misses.
A Documented Sign-Off
The reviewer’s conclusion, corrections recommended, and formal acceptance status are logged and retained - so the client has an audit trail, not just a delivered file.
Other Important Translation Notes
- ›On this project, the review log recorded five issues, all classified as minor and non-critical. The terminology and phrasing examples below are illustrative, re-created examples of each issue type - not verbatim excerpts from the client’s actual document.
- ›Inconsistent terminology for a single recurring term: the English word "wipe" had been rendered four different ways across the document instead of one consistent term - a common failure point when a document is translated in sections, or by more than one translator, without a shared glossary. EN: "Discard the used wipe after each application." As found (inconsistent): "Әр қолданудан кейін пайдаланылған сүлгіні тастаңыз." Corrected (standardised, used consistently throughout): "Әр қолданудан кейін пайдаланылған майлықты тастаңыз."
- ›Inconsistent rendering of a key technical phrase ("high-level disinfection"), translated differently depending on where it appeared in the document. EN: "…for the high-level disinfection of medical devices." As found (inconsistent): "медициналық құрылғылардың жоғары деңгейлі дезинфекциясы үшін" Corrected: "медициналық құрылғыларды жоғары деңгейде зарарсыздандыру үшін" - both fragments end mid-sentence in the source, matching the EN’s own leading ellipsis.
- ›One non-standard technical term: a source concept ("bioburden") had been translated using a term not in standard use in Kazakh medical/technical literature. EN: "…designed to reduce bioburden on the surface of the device." As found (non-standard): "құрылғы бетіндегі биосалмақты азайтуға арналған" Corrected (standard term): "құрылғы бетіндегі микробтық жүктемені азайтуға арналған" - again a mid-sentence fragment in the source, matching the EN’s leading ellipsis.
- ›A grammatical error in an instructional verb form - the kind of slip that doesn’t change meaning to a native reader but reads as unpolished in a document meant to represent a manufacturer’s professional standards. EN: "Do not shake the bottle before use." Incorrect verb form (as found): "Пайдаланар алдында бөтелкені шайқалмаңыз." Corrected: "Пайдаланар алдында бөтелкені шайқамаңыз."
- ›One outright mistranslation of a product-handling term, flagged, corrected, and verified before sign-off. EN: "Apply the dry wipe to the surface of the device." Mistranslated (as found): "Құрылғы бетіне жапқышты жағыңыз." (translates back as "cover/lid," not "wipe") Corrected: "Құрылғы бетіне құрғақ майлықты жағыңыз."
- ›Critically: no critical omissions, and no changes to intended use, safety warnings, or the procedural steps themselves. The deviations were terminological and editorial - exactly the category of issue a structured review process is designed to catch before a document reaches print or a hospital shelf, rather than after.
Key Challenge
None of the issues above would necessarily have been caught by a single translator working alone, however skilled - that’s precisely why a second, independent, in-country review step exists. For medical device documentation specifically, terminology consistency isn’t a stylistic nicety: inconsistent terms for the same object across a document can create genuine confusion for a clinical end user, even when each individual translation is technically correct. This is the standard we apply to every English-to-Kazakh technical and regulatory project - not just medical devices, but pharmaceutical labeling, industrial equipment manuals, and any content where a translation error has consequences beyond an awkward sentence.
