Heath Considerations

The polygraph components are not invasive. The polygraph instrument uses sensors placed on an individual to measure, monitor and record changes in their physiological state during the testing phase of the examination. It is highly unusual for any medical condition, past or present to interfere with the testing process or examination results. In the event you have a concern, it is best to consult a physician prior to scheduling the examination.


Your polygraph is held in the strictest of confidence. We ask that you maintain confidentiality regarding your polygraph and do not discuss it with acquaintances, friends, family, or co-workers.
