By Polygraph Testing we can analyze the true profile of the person to be examined based on the physiological reactions when answering previously formulated questions related to various events or acts involving the subject. The results are recorded by means of a graph visualizing physiological reactions (heart rate, sweat and etc.) when questions are answered. When all relevant requirements before and during testing are met, the Polygraph Test has a scientifically proven effectiveness of 98%.
