About Our Polygraph Examination Process
At Newcomer Polygraph Services LLC, we combine nearly two decades of experience with cutting-edge Lafayette LX 7000 computerized polygraph technology to deliver accurate, defensible results. Our examination process is designed to be thorough yet respectful, ensuring both the integrity of physiological data and the dignity of the examinee.
90-Minute Examination
Each polygraph examination takes approximately 90 minutes and follows standardized protocols established by the American Polygraph Association.
Three Physiological Indicators
We monitor cardiovascular activity, respiratory patterns, and galvanic skin response using our computerized system for precise measurements.
24-Hour Reports
Detailed reports delivered within 24 hours, suitable for legal proceedings and trusted by law enforcement agencies.
What to Expect During Your Examination
We begin with a detailed pre-test interview to understand your case specifics and address any concerns. During the actual examination, our certified examiner interprets physiological responses using proven methodologies. Our computerized system provides precise measurements that ensure objectivity and accuracy.
Our Success Rate & Reliability
We achieve conclusive results in 95% of examinations. When results are inconclusive, it's typically due to medical factors, anxiety, or medications—never due to examiner error. We document all influencing factors and provide clear explanations in our detailed reports.
