The lie detector test records manifestations of a persons central nervous system from at least three systems in the body whilst questioned about concerns of specific issue, incident or event. The examiner will analyse the charts collected and render an opinion as to the persons truthfulness. The examination consists of four phases and will typically take between 2-3 hours.  The four phases of an examination are referred to as the pre-test, chart collection, test data analysis and the post-test phase.

Although no forensic testing of any kind can be guaranteed to be 100 % accurate, research gathered by The American Polygraph Association has suggested that qualified polygraph examiners can achieve an accuracy of 95% to 98% when an examination is conducted in an accurate manner, with issue-specific questions and using validated polygraph techniques.

Lie Detector Investigations work to specific key conditions, using robust policies and best practices. Each test is quality controlled by a second examiner and our written reports are also verified, unless otherwise requested by our client.
