Выражение встречается в следующем контексте: A participant in a clinical study. A subject maybe healthy or have a
disease. For obtaining informed consent, this term also includes
legally acceptable representative where applicable.
Т.е., "в некоторых случаях, особенно при получении информированного согласия, термин участник клинического исследования может относиться и к уполномоченному представителю добровольца"???

Заранее спасибо

informed consent -
An agreement to do something or to allow something to happen, made with complete knowledge of all relevant facts, such as the risks involved or any available alternatives. For example, a patient may give informed consent to medical treatment only after the healthcare professional has disclosed all possible risks involved in accepting or rejecting the treatment. A healthcare provider or facility may be held responsible for an injury caused by an undisclosed risk. In another context, a person accused of committing a crime cannot give up his constitutional rights--for example, to remain silent or to talk with an attorney--unless and until he has been informed of those rights, usually via the well-known Miranda warnings
