The use of several or a whole battery of screening tests to search for early evidence of a wide variety of preventable diseases and precursors of disease. The process is often automated. It may begin with a self-completed questionnaire entered into a computer and using a touch-screen or keyboard for responses, followed by a set of routine body measurements (height, weight, etc.); a wide range of blood tests, respiratory function tests, chest x-ray, electro cardiogram, and other tests. Economies of scale may make this approach worthwhile, but false-positive results may lead many people to be subjected to further costly tests and needless anxiety.
