Wilson and Jungner criteria for disease screening

1The condition sought should be an important health problem.
2There should be an accepted treatment for patients with recognised disease.
3Facilities for diagnosis and treatment should be available.
4There should be a latent or early symptomatic stage.
5There should be a suitable test or examination.
6The test should be acceptable to the population.
7The natural history of the condition, including development from latent to declared disease, should be adequately understood.
8There should be an agreed policy on who to treat as patients.
9The cost of case finding (including diagnosis and treatment of patients diagnosed) should be economically balanced in relation to possible expenditure on medical care as a whole.
10Case finding should be a continuing process and not a ‘once and for all’ project.
