Polygraph Tests in Castellón de la Plana: Professional Appointments by Prior Booking
A polygraph test in Castellón may be appropriate when a statement concerns a specific incident: missing money, a possible workplace breach, a relationship matter or a disagreement between business partners. During the initial consultation, we determine whether the circumstances can be addressed through clear, specific questions covering a defined period.
The session begins with a pre-test interview to review the background and explain the procedure. Participation is voluntary, and physiological recordings are not, on their own, direct proof of deception. Any conclusions must be interpreted in light of their technical limitations.
Our reference address is Carrer de Cerdà de Tallada, 77, 12004 Castelló de la Plana. We accept enquiries from the city and neighbouring towns including Vila-real, Borriana, Almassora, Benicàssim, Onda and La Vall d’Uixó, always by confirmed appointment.

Polygraph Methodology, Pre-Test Interview and Technical Analysis
A polygraph records changes in physiological activity during a series of questions. These recordings do not in themselves directly prove that someone is lying: they require a defined protocol, suitable conditions and specialist interpretation.
INTERPOLYS prepares each assessment by reviewing the case, verifying consent, developing the questions and subsequently analysing the results. The European Polygraph Association (EPA) and the American Polygraph Association (APA) publish professional guidance and standards for the field.
The reported accuracy of up to 98% depends on the methodology, suitability of the case and testing conditions; it does not guarantee the outcome of an individual examination. Results should be considered alongside all other available information.
