Screening tests are any test conducted in the absence of a known problem or known incident. In the
medical and psychological professions screening tests are conducted in the absence of any known
symptoms. Screening tests are intended to gather a range of information and therefore may be
conducted regarding multiple independent target issues. Screening tests may also address a single issue
of concern (in the absence of a known problem). Investigative testing is a more general term that refers
to any polygraph test conducted in the context of an investigation, whether background, incidental,
criminal investigation or screening
