Primary: Preventing disease/injury before it occurs.
Examples: Immunization, walkable communities, seatbelts, legislation for safe practices.
Secondary: Early detection and intervention.
Examples: Regular exams and screening tests.
Tertiary: Managing disease to slow or stop progression, reduce complications, and improve quality of life.
Examples: Case management, diabetes management classes, support groups, therapy.
Screening Test:
Identifies asymptomatic people possibly having a disease.
Diagnostic Test:
Determines presence/absence of disease when patient shows signs/symptoms.
Simple, Safe, Available, Acceptable, Inexpensive, Rapid.
Examples: Pap smears, fasting blood sugar (FBS), mammograms, blood pressure screening.
Early detection leads to early treatment, breaking transmission chains and is often cost-effective.
Screenings start BEFORE diagnosis via:
History questions.
Physical exam findings.
Lab tests.
Pre-test probability.

Reliability: Consistency of a test.
Types:
Intra-Subject: consistency within the same subject across occasions.
Intra-Rater: consistency by the same tester.
Inter-Rater: consistency between different testers (most important for screening tools).
Instrument: internal consistency of the measurement tool.
Validity: How well the test distinguishes between those with and without the disease.
