What is a polygraph test?

The Polygraph Test system does not actually recognise lies, instead it records the activity of the subject undergoing the test. The examination will test the subjects physical and verbal responses to a series of pre-arranged questions, the test monitoring a variety of factors including breathing, voice, heart beat, blood pressure and moisture and electrical activity. After the questions have been answered by the subject then our trained examiner will evaluate the results of the test and will be able to provide a report on the findings and whether key questions were a 'pass' or a 'fail'.
