How does a polygraph test work?

A polygraph examination consists of three phases:
1. Pre-Test - This is the phase in which information about the person is collected and relevant questions or statements are formulated.
2. In-Test - This is the test phase in which data are collected through our state-of-the-art equipment.
3. Post-Test - This is the phase in which our certified polygraph examiner analyzes the data and determines whether the person is lying or telling the truth.
