Lie Detector Test Process



We work closely with you to formulate appropriate questions specific to the truth you need to find. Whether in the pre-employment screening process, theft, fraud or anything else that is bothering you.

Normally up to 8 questions are asked with 2-3 of them relevant to the matter you are concerned about. The other questions proposed are for profiling purposes, related to behaviour and metrics. You may want to know if your data has been passed to a competitor, or what the subject knows about theft of equipment or assets. Questions must always be related to factual matters rather than opinion. The test may take up to 2 hours depending on how complex the issue is which includes the pre-test interview.


Pre-Test Interview

First a statement of consent to conduct the test is obtained. Then the pre-test interview will commence with the discussion of a number of questions, including those that you have predetermined with us.

The purpose of the pre-test interview is to ensure the subject is relaxed and understands completely what the test is about. The predetermined questions and the way they are worded are suggested by the examiner since they need to be defined and close ended.

The most accurate results from the polygraph come with perfectly worded and contextualised questions are asked.



The polygraph test takes a minimum of 30 minutes, but can take anywhere up to four hours depending on the issue being tested for.

Following the pre-test interview, a data collection phase commences which includes attaching the components to the examinee, which includes upper body movement sensors attached to the chest. A standard blood pressure cuff is attached to the upper arm and is inflated, to record reading of the examinees heart rate and pulse rate. Electrodermal activity finger cuffs are attached to two fingers to measure skin conductance (sweat gland activity). The examinee may also sit on a movement sensor mat.

Once complete the examiner will analyse the results and provide an opinion as to the truthfulness of the person taking the test depending on the test type. You will get the results the same day verbally via a phone call, followed up by a written report emailed or posted.


Results & Reports

If the issue has been a simple one, and the result is considered conclusive at the end of the test, our examiner will immediately apprise the client verbally if required. To be precise our client is the individual who booked the test. Unless otherwise advised in writing that we may share the results of the test with a 3rd party we will never do so.

Detailed analysis of the resulting transcripts, video and charts will be undertaken by the examiner who performed the polygraph test. It will then be verified by another equally qualified and accredited examiner before the report is sent to the client, usually within 48 hours.

There are a many benefits for companies to introduce Business Polygraph Testing into the recruitment or loss prevention strategy. You can rely on us to advise you how to implement it effortlessly without distressing your staff.
