Screening tools are instruments or tests used to identify individuals who are at risk for a particular condition or disorder. These tools are typically used in healthcare settings to help healthcare professionals quickly and efficiently identify individuals who may need further evaluation or treatment. Screening tools vary widely depending on the condition being screened for, but they can include questionnaires, physical exams, laboratory tests, or imaging studies. These tools are often used in population-based screening programs to identify individuals who may be at risk for conditions such as cancer, heart disease, mental health disorders, or developmental delays. Overall, screening tools play a crucial role in early detection and prevention of health problems, as they can help identify at-risk individuals before symptoms appear or a condition progresses to a more serious stage.
