text: <unk>  in medicine, is a strategy used to identify disease in an unsuspecting population. Unlike most medicine, in<unk>  tests are performed on those without any clinical indication of disease.
  The intention of<unk> is to identify disease in a community early, thus enabling earlier intervention and management in the hope to reduce mortality and suffering from a disease. Although<unk> may lead to an earlier diagnosis, not all<unk> tests have been shown to benefit the person being screened; overdiagnosis, misdiagnosis, and creating a false sense of security are some potential adverse effects of<unk>   For these reasons, a test used in a<unk> program, especially for a disease with low incidence, must have good  specificity in addition to acceptable sensitivity.
