Before the examination

Every examination begins with a confidential conversation. The examiner explains what will be measured, answers your questions, and confirms that your participation is voluntary. Nothing is recorded or discussed outside the appointment.

During the examination

The instrumentation records respiration, cardiovascular activity, and electrodermal response while a set of agreed questions is asked. The examiner reviews each question with you beforehand so there are no surprises.

After the examination

Findings are explained clearly, and a written report is available when you need documentation for an attorney or another professional.
