Polygraph Tests in Barcelona: Professional Assessments in L’Eixample
In a city with such varied commercial and business activity as Barcelona, polygraph enquiries may concern internal incidents, disagreements between business partners or personal circumstances. INTERPOLYS reviews each request to determine whether clear, appropriate questions can be formulated.
The assessment begins with a preliminary interview and a review of the questions. Where the case is suitable, psychophysiological recording follows. A polygraph does not directly detect lies: its results require technical interpretation and must be understood within the method’s limitations.
Our reference address for pre-arranged appointments is Carrer del Rosselló, 17, Eixample, 08029 Barcelona, in the L’Eixample district. We receive enquiries from Barcelona and surrounding municipalities, including L’Hospitalet de Llobregat, Badalona and Sant Cugat del Vallès.

Polygraph Methodology, Pre-Test Interviews and Technical Analysis
A polygraph records changes in physiological activity during a series of questions. These recordings are not, by themselves, direct evidence of deception: they require a defined protocol, suitable conditions and specialist interpretation.
INTERPOLYS prepares each examination by reviewing the case, confirming consent, drafting questions and subsequently analysing the recordings. The European Polygraph Association (EPA) and the American Polygraph Association (APA) publish professional guidance and standards for the industry.
The stated accuracy of up to 98% depends on the methodology, case suitability and examination conditions; it does not guarantee accuracy in an individual case. Results should be considered alongside all other available information.
