Medical translation is the translation of technical, regulatory, clinical or marketing documentation, software or training curriculum for the pharmaceutical, medical device or healthcare fields. Most countries around the world require that literature and labeling associated with medical devices or pharmaceuticals sold be translated into the national language(s). In addition, documents necessary to conduct clinical trials often require translation in order for local clinicians and patients and regulatory representatives to be able to read them. Regulatory approval submissions typically have to be translated as well.
