Medical translation is the practice of translating various documents—training materials, medical bulletins, drug data sheets, etc.—for health care, medical devices, marketing, or clinical, regulatory, and technical documentation. Most countries require that companies and organizations translate literature and labelling for medical devices or pharmaceuticals into their national language. Documents for clinical trials often require translation for local clinicians, patients, and regulatory representatives. Regulatory approval submissions typically must be translated. In addition to linguistic skills, medical translation requires specific training and subject matter knowledge because of the highly technical, sensitive, and regulated nature of medical texts.
