A small number of disease processes can be diagnosed by your doctor after an adequate history has been taken and the doctor has examined you. However, many diseases are not discreetly identifiable with merely your doctor’s history and examination and you must rely on extra information that he can obtain. This extra information is either obtained through pictures of the inside of your body (radiological investigations) or blood tests which give information on how your body may be reacting to any disease processes.
Equipped with the history and physical examination and the results of further investigations, the doctor has a better chance of accurately diagnosing your condition and therefore treating you appropriately.
