1. Introduction\u00a0<\/h2>\n

This guide is part of the 1-StopAsia Orange Book Series. It documents the quality standards applied by our Thai linguistic and medical QA teams when working on medical content for which no client-defined style guide exists.<\/p>\n

Thai medical localization requires more than linguistic accuracy. A translator with native Thai fluency and general translation skills will still produce substandard medical content without explicit training in the conventions documented here. Medical content also carries patient-safety stakes that ordinary copy does not: a mistranslated symptom, an altered dose, or a clinical term confused with an everyday word can cause real harm. Thai adds its own pressures: the absence of spaces between words, the decision of whether to transliterate or translate drug and device names, and a sharp divide between the register used for clinicians and the plain language required for patients.<\/p>\n

This document is organized into five sections:<\/p>\n

    \n
  • Terminology and Proper Name Handling: <\/strong>How drugs, devices, and clinical terms should appear in Thai, and when to transliterate them rather than translate.<\/li>\n
  • Register and Tone for Medical Content: <\/strong>The register choices that distinguish clinician-facing documentation from patient-facing materials.<\/li>\n
  • Readability and Sentence Structure: <\/strong>The structural errors that most consistently reduce Thai medical copy to literal translation.<\/li>\n
  • Idiomatic and Clinical Expression: <\/strong>How English medical idioms and figurative phrasing must be recast for Thai audiences.<\/li>\n
  • Punctuation, Format, Numbers, and Units: <\/strong>Thai-specific formatting rules, including the safety-critical handling of doses, units, and ranges.<\/li>\n<\/ul>\n
    \n\u26a0 Medical Note: <\/strong>This guide applies when no client instruction, translation memory, glossary, approved terminology list, or style guide is available. When client materials or approved drug nomenclature exist, those always take precedence. Any safety-critical ambiguity (dose, route, frequency, contraindication) must be raised with the PM before the project begins.<\/div>\n

    2. Terminology and Proper Name Handling (\u0e04\u0e33\u0e28\u0e31\u0e1e\u0e17\u0e4c\u0e40\u0e09\u0e1e\u0e32\u0e30\u0e17\u0e32\u0e07\u0e41\u0e25\u0e30\u0e01\u0e32\u0e23\u0e17\u0e31\u0e1a\u0e28\u0e31\u0e1e\u0e17\u0e4c)<\/h2>\n

    Incorrect handling of drug names, device names, and standardized clinical terms is among the most consistent errors in Thai medical localization. Non-specialist translators tend either to invent ad-hoc transliterations or to misspell established clinical terms that have a single correct Thai form.<\/p>\n

    2.1 Drug, Device, and Ingredient Names<\/h3>\n

    [PN001] Drug and Device Proper Names<\/strong><\/p>\n

    Brand drug names, device names, and manufacturer names are generally not translated. Active ingredients (generic \/ INN names) follow approved Thai nomenclature where one exists; otherwise they are transliterated per the principles in 2.2. When an officially registered Thai name exists, always use that form rather than a fresh transliteration<\/p>\n\n\n\n\n\n\n

    \n\u26a0 Verification required: <\/strong>Drug, device, and active-ingredient names are not present in the internal Thai quality file. Every name shown here is illustrative and must be verified against the client glossary and Thai FDA (\u0e2d\u0e22.) approved nomenclature.<\/div>\n
    \n\u26a0 Medical Note: <\/strong>When a client has an officially registered Thai drug or device name, always use it. It may differ from a direct transliteration. Verify with the PM when in doubt and never guess a drug name.<\/div>\n

    2.2 Transliteration of Medical and Scientific Terms<\/h3>\n

    [PN002] Transliteration Principles<\/strong><\/p>\n

    Many medical and scientific terms are conventionally transliterated into Thai in a single standardized form. The most common error is an ad-hoc spelling that departs from the established transliteration. The forms below are drawn from the internal Thai transliteration standard.<\/p>\n\n\n\n\n\n\n\n

    2.3 Standardized Clinical Spelling<\/h3>\n

    [TM001] Anatomical and Clinical Term Spelling<\/strong><\/p>\n

    Several anatomical and clinical terms have one correct Thai spelling and a set of common misspellings. These are non-negotiable: the wrong spelling marks the content as non-specialist and, for some terms, risks confusion with an unrelated everyday word.<\/p>\n\n\n\n\n\n\n\n\n\n

    3. Register and Tone for Medical Content (\u0e23\u0e30\u0e14\u0e31\u0e1a\u0e20\u0e32\u0e29\u0e32\u0e41\u0e25\u0e30\u0e19\u0e49\u0e33\u0e40\u0e2a\u0e35\u0e22\u0e07)<\/h2>\n

    The single most important register decision in Thai medical content is the audience. Content written for clinicians can use technical terms and the verbs of administration; content written for patients must use plain, everyday Thai and the verbs patients use about themselves. Using clinician-style registers in a patient leaflet, or vice versa,\u00a0 is a quality failure even when every word is technically correct.<\/p>\n

    3.1 Audience Register<\/h3>\n

    [MD001] Clinician-Facing vs. Patient-Facing Register<\/strong><\/p>\n

    Match register to the reader. Patient instructions use the verbs patients use (\u0e23\u0e31\u0e1a\u0e1b\u0e23\u0e30\u0e17\u0e32\u0e19 \/ \u0e43\u0e0a\u0e49), not the clinician verb of administration (\u0e43\u0e2b\u0e49\u0e22\u0e32), which belongs in nursing or prescribing documentation.<\/p>\n\n\n\n\n\n

                This guide is part of the 1-StopAsia Orange Book Series, our published quality standards for Asian-language content across core domains. The Orange Books document the standards our in-house linguistic teams apply when clients have not defined their own quality criteria.<\/p>\n

                We publish them because we believe quality in localization should be transparent, not assumed. An LSP or enterprise buyer working with 1-StopAsia on Thai medical content should be able to understand exactly what standard their content will be held to, and why.<\/p>\n

                Scope and Limitations<\/strong><\/p>\n

                This guide covers Thai medical translation \/ localization quality standards across clinical, patient, pharmaceutical, and regulatory content. It does not substitute for:<\/p>\n

                  \n
                • Client-provided style guides, glossaries, or translation memory (which always take precedence)<\/li>\n
                • Approved Thai drug nomenclature and Thai FDA (\u0e2d\u0e22.) requirements<\/li>\n
                • Regulatory and legal requirements for specific product categories or claims<\/li>\n
                • Clinical review and sign-off of safety-critical content (dose, route, contraindication)<\/li>\n<\/ul>\n

                  Updates and Feedback<\/strong><\/p>\n

                  This guide is reviewed annually by the 1-StopAsia Thai medical QA team. Feedback from clients, reviewers, and project managers is incorporated into each revision. If you identify a case not covered here, or believe a standard requires revision, contact your 1-StopAsia project manager.<\/p>\n
