Health Screening Profile Image

Health Screening

Health screening is designed to identify disease in a community early, thus enabling earlier intervention and management in the hope to reduce death and suffering from a disease.

Overview

Screening can detect medical conditions at an early stage before symptoms present while treatment is more effective than for later detection. In the best of cases lives are saved.

Like any medical test, the tests used in screening are not perfect. The test result may incorrectly show positive for those without disease, or negative for people who have the condition.

Limitations of screening programmes can include:

  • Screening incurs costs for a majority of people who do not need treatment.
  • Adverse effects of screening procedure (e.g. stress and anxiety, discomfort, radiation exposure)
  • Stress and anxiety caused by a false positive screening result.
  • Unnecessary investigation and treatment of false positive results
