What Is a Polygraph Test?

A polygraph test - often referred to as a lie detector test - measures physiological responses such as heart rate, blood pressure, respiration, and perspiration while a person answers a structured series of questions. These physical responses help indicate whether a person is being truthful or deceptive in their answers.

At JCS Investigations, our certified polygraph examiners follow scientifically recognized protocols to ensure accuracy and fairness. Each examination includes:

• A pre-test interview to review questions and establish comfort
• The testing phase, during which responses are recorded and monitored
• A post-test analysis, where data is interpreted and a final report is prepared

Our results are clear, professionally documented, and suitable for personal, legal, or corporate use.

When to Use Polygraph Testing

Polygraph testing can be a valuable tool in a wide range of personal, civil, and professional situations. Common applications include:

• Criminal investigations to verify statements or confirm facts
• Infidelity or family disputes to establish truthfulness in sensitive matters
• Employment screenings for positions involving trust or security
• Theft and fraud investigations within companies or organizations
• Legal cases where evidence or witness testimony is in question

Each test is tailored to the unique context of the case, ensuring the questions are fair, relevant, and legally appropriate.
