The invention provides a method and system by which research data can be collected and analyzed during the course of the research testing, and the research testing itself possibly modified to account for conclusions drawn from the research data. In a first aspect of the invention, a research subject can respond to a protocol stored on a server by manipulating input keys on a remotely located client device onto which a research protocol has been installed. The protocol can include questions concerning the subject's physical or mental well being such as whether their symptoms are relieved or not, or even exacerbated. The protocol can also include calling for data obtained by coupling the client device with another medical device such as a glucose monitor. In a preferred embodiment, the subject is presented with narrowly structured questions and suggested answers provided by the protocol. The set of possible answers is restricted. In the event that a suggested answer is ambiguous, inapplicable or raises new questions, a protocol can present a new question to the subject.
