Screening methods are techniques used to identify individuals who may have a specific condition or disease. These methods can include questionnaires, physical exams, and laboratory tests. The goal is to detect potential health issues early, allowing for timely intervention and treatment. Common examples of screening methods include mammograms for breast cancer and blood tests for diabetes. Screening can be applied in various settings, such as hospitals, clinics, and community health programs. It is essential for preventive healthcare, as it helps reduce the risk of severe complications by catching diseases in their early stages. Effective screening methods can improve overall health outcomes for populations.
