Polygraph examinations are used to verify the truth and determine deception. In both civil and criminal matters, polygraph examinations can enhance an investigation by helping to clear the innocent and identify the guilty.

A typical polygraph examination will include a period referred to as a pre-polygraph interview, a chart collection phase, and a test data analysis phase. All phases of the polygraph examination can take anywhere from an 1 1/2 to 2 hours.
