About Medical Billing Services

Local Polygraph & Lie Detection Services provides law enforcement with an investigative tool in criminal proceedings and the private citizen with a valuable tool in personal, marital, or civil proceedings. Many employers now require that a person take a polygraph through the Local Polygraph & Lie Detection Services before being employed. This is especially true for employment in law enforcement agencies or when employed where contact with children is necessary. Local Polygraph & Lie Detection Services provides certified and highly trained professionals to administer the testing. Testing is done in a low stress room with no distractions or noise. The person remains clothed. Local Polygraph & Lie Detection Services rely on the bodys responses to the stress of lying to determine if the person is telling the truth. Sensors are placed at various points on the subjects body while the person sits quietly in a chair. These sensors are attached to a machine that monitors responses and graphs them onto a computer. This is a totally painless and non-intrusive test. Local Polygraph & Lie Detection Services will begin with a pre-interview, asking a series of questions that the person will be able to respond truthfully to, such as, Is your name Bill? Or are you 54 years old? The subject will also be asked if they are using any type of drug which can affect the outcome of the test. By replying to these questions and others during the pre-interview the Local Polygraph & Lie Detection Services examiner is able to see what the subjects normal, truthful response looks like on the graph. It provides a baseline for comparison with final results. The individual will also be told what questions will be asked during the procedure so that there are not any surprise questions.

More on Polygraph - Lie Detection Services

Local Polygraph & Lie Detection Services examiners are looking for four main physical responses. It is common for respiration (breathing rate) to increase when a person is lying. Blood pressure usually increases during stress and is another response that is monitored. Pulse rate is monitored. The final response monitored is perspiration. People start sweating when they are in stress, and lying induces stress in the body. Some Local Polygraph & Lie Detection Services will also monitor leg and arm movements. By comparing the test results to the baseline that was obtained during the pre-interview, Local Polygraph & Lie Detection Services examiners can determine if a subject was answering truthfully on specific questions. They will also be able to determine if the person was trying to beat the test by controlling their breathing and heart rate. If so, the test might have to be repeated. Local Polygraph & Lie Detection Services specialists will then decide if the person was answering truthfully or deceitfully or if the test came back inconclusive, where truthfulness cannot be determined. The results from a polygraph are not admissible in court, but are invaluable when trying to determine if a person is lying about an event or his /her involvement in that event.
