This is generally the detection of specific diseases that can be controlled better when detected early in their natural history in individuals or groups who may be predisposed to that disease, for example, individuals with particular risk factors.
CODE 4 Asymptomatic - diagnosis via organised screening:
The detection of unrecognised diseases or conditions in a specific population of people by using reliable tests, examinations or other procedures which can be applied rapidly as part of an organised screening program.
