Medical Translation

The second defining feature of the field is the range of readers. For one and the same medicine, the product information written for a doctor and the leaflet written for the patient carry the same facts in an entirely different register. A text cannot be translated correctly without knowing who it addresses.

Which texts count as medical translation?

The scope runs from clinical documents to regulatory files. On one side are patient records, discharge summaries, test results and operation reports; on the other, instructions for use for medical devices, clinical trial protocols and informed consent forms. The two groups call for different expertise and a different order of checks.

Document	Reader	Register	Critical risk
Discharge summary and test result	Doctor	Specialist terminology, abbreviations	Errors in units and reference ranges
Informed consent form	Patient	Plain, accessible language	Risks explained incompletely
Patient information leaflet	Patient and family	Imperative mood, short sentences	Wording of dose and frequency
Device instructions for use	Healthcare staff	Technical, standards-compliant	Warning and caution text
Clinical trial protocol	Investigator and review board	Scientific, formal	Inclusion and exclusion criteria

Terminology, abbreviations and units

In medical language an abbreviation can carry different meanings depending on context; the same three letters may point to two different diagnoses in two different specialties. Abbreviations are therefore resolved from the clinical context of the text, not from a dictionary. Where certainty is not possible, the abbreviation is expanded and the form used in the source kept in brackets.

Units of measurement are the second critical area. Unit systems in laboratory results vary from country to country, and whether or not to convert them is a medical decision rather than a translation one. The sound approach is to carry the value and the unit across exactly as the source has them and, where necessary, to point out the difference in a translator’s note.

How the process works

1. The type of text, its intended reader and the use it will be put to are established; a patient file and a marketing authorisation dossier do not follow the same route.
2. A translator with the relevant specialist background is assigned; oncology, cardiology and orthopaedic texts each demand command of a different terminology.
3. While the translation is under way, all numerical data is collected in a separate list.
4. A second person compares that list against the source document independently; this step is carried out apart from the reading of the text.
5. A review is carried out by someone experienced in healthcare; anything left uncertain is marked with a translator’s note.
6. The work is delivered and the term record specific to the file is retained.

Confidentiality and patient data

Health data forms a separate and more strongly protected category within personal data. The translation of a discharge summary carries that person’s diagnosis, their history and sometimes information about their family as well. In medical translation, therefore, how many people handle the file, where it is stored and when it will be deleted should be settled at the outset.

For corporate work, the expected practice is that identifying details are masked wherever they are not needed and that the translation team works under a written confidentiality undertaking. For individual patient files, an undertaking that the file will be destroyed once the work is finished is the least that should be expected.

Clinical trials and regulatory documents

The second large branch of medical translation is made up not of clinical texts but of regulatory files. Clinical trial protocols, participant information sheets, case report forms and correspondence with ethics committees belong to this group. Here the translation forms part of an official dossier that a committee will examine, and it is subject to formal requirements.

The criterion that stands out in this area is consistency. Inclusion criteria, dosing schedules and assessment time points appearing in different sections of the same protocol have to match one another exactly. A contradiction present in the source text is not put right in the translation; it is flagged and reported to the responsible investigator.

Participant information sheets raise a language problem of their own. Such forms tend to be written like legal instruments, yet the reader they are meant for is a patient. The aim in translation is to keep the text genuinely comprehensible while preserving its legal scope; striking that balance takes experience in the field.

Medical device texts are a discipline of their own

Instructions for use for medical devices sit where medical and technical translation meet. The text describes clinical use on one hand and is an engineering document on the other. The form of the warning and caution sections is often laid down in the applicable standards, and it is here that the translator’s latitude is at its narrowest.

The second feature is interface text. The messages on a device screen are limited by character count and must match their counterparts in the manual word for word. If the step the manual calls the “wash cycle” appears on screen under another name, the user cannot confirm which step they are on.

The third point is version control. When device software is updated the manual is updated with it, and in those updates only the sections that have changed should be worked on, the rest being kept as previously approved. Translations without version traceability cause trouble at audit.

Files for treatment abroad

The files of patients seeking treatment abroad sit where clinical translation meets official document translation. Discharge summaries, imaging reports and medication lists call for clinical expertise; insurance and reimbursement correspondence and hospital admission documents, by contrast, usually require an attested translation.

The most common loss in these files is a treatment history sent in fragments. Where the patient’s earlier tests and current medication are passed on incompletely, the receiving clinic asks for further documents at the first assessment and the process takes another turn. Arranging the file in chronological order and completing the missing pages from the start saves weeks on its own.

Imaging reports carry a further technical detail: the text of the report and the image files themselves have to be sent separately. The receiving clinic will usually have the raw images read again by its own specialist; the translated report accompanies that reading rather than standing in for it. Knowing this distinction makes it easier to decide correctly which documents need translating.

What determines the price?

The first factor in the price of a medical translation is the depth of specialism; there is a considerable difference in cost between general healthcare texts and advanced specialist material. The second is handwritten content: files containing doctors’ notes take far longer than digital text. The third is the extent of the second layer of checking.

For files prepared in support of an application for treatment abroad, a layer of attestation may also come into play. We set out the pricing logic item by item on the pricing page; for how the destination country accepts documents, see the country guide.

Situations that come up often

• Illegible handwriting. A word that cannot be read with certainty is never guessed at; it is flagged and confirmation is sought from the doctor who wrote it.
• Missing pages. The reverse of a discharge summary often carries the medication list; when it is skipped in scanning, the treatment history looks incomplete.
• Medicine names. The brand name of the same active substance changes from country to country. The sound approach is to work from the active substance while keeping the brand name as well.
• Time pressure. In health tourism the quote stage moves quickly; but speed must not mean skipping the numerical verification step. You can send your file through the quote form.

The account here summarises typical practice; the practice of an individual institution may differ. We recommend following the rules in force through official announcements.
