Question 1

Principles of screening

Answer 1

• should be an important health problem
• should be a recognisable latent or early symptomatic stage
• natural history of the condition, including development from latent to declared disease, should be adequately understood
• there should be an accepted treatment for patients with recognised disease
• suitable test or examination that has a high level of accuracy
• the test should be acceptable to the population
• there should be an agreed policy on whom to treat as patients
