Preview

Screening has been defined as “examination of asymptomatic people in order to classify them as likely, or unlikely, to have the disease that is the object of screening.” Screening can also be applied to detect modifiable risk factors for disease, such as high blood pressure or high serum cholesterol levels, that may not otherwise be apparent. This chapter discusses when screening can be justified, assessing screening test performance, and evaluating the effectiveness of screening. Exercises are provided at the end of the chapter.
