Lie Detector & Polygraph Testing Services

A polygraph examination tests a subject’s verbal and physical responses to a series of questions asked by a trained examiner. The subject is attached to a polygraph instrument that records their breathing, galvanic skin response and heart beat/blood pressure. After the questions have been answered the examiner will make a pass/fail determination based on their evaluation of the data. The results of polygraph testing are at least 90% accurate and have been admitted as evidence in courts of law for or against the truthfulness of an eyewitness.
