A polygraph examiner is a specialist who uses a lie detector to help establish the truth where guesswork no longer works and decisions have to be based on facts. Polygraph Lviv has been working since 2012, uses two independent methods (the classic polygraph and EyeDetect/VerifEye) and guarantees complete confidentiality. Call: +380 96 96 111 96.
Who a polygraph examiner is and what their services include
A polygraph examiner is a certified specialist in psychophysiological examinations. The examiner prepares the questions, conducts the lie detector test and analyses the person’s reactions to arrive at an objective conclusion. The quality of a polygraph examiner’s services depends on the method, properly worded questions and the expert’s qualifications, not on the “magic of the device”.

Technologies a polygraph examiner works with
A modern polygraph examiner uses more than just the classic instrument. Polygraph Lviv offers three technologies:
- Classic polygraph — contact sensors record physiological reactions.
- EyeDetect — contactless analysis of eye movements. No sensors, up to 45 minutes including the result (accuracy 86–90%).
- VerifEye — an online lie detector on your smartphone. Remote, the test takes 10–25 minutes (accuracy 84–89%).
| Technology | Accuracy | Time | Format | Price |
|---|---|---|---|---|
| Classic polygraph | 85–89% | 1.5–3 hours | Contact, in the office | 3,000–8,000 UAH (≈ €59–160) |
| EyeDetect | 86–90% | up to 45 min including the result | Contactless, in the office | from 5,500 UAH (≈ €110), in Lviv |
| VerifEye | 84–89% | 10–25 min | Online, remote | from 2,500 UAH (≈ €50) |
How the test works — step by step
- Consultation — you describe the situation and the purpose of the test (free of charge).
- Pre-test interview — the examiner explains the rules and eases any unnecessary anxiety.
- Preparing the questions — short, unambiguous, with no hidden meaning.
- Testing — several series of questions for a stable result.
- Analysis and conclusion — a written report within 2–3 hours.
What questions a polygraph examiner asks
For the test to give a practical result, the questions must be specific and limited to the event. Good: “Did you take money from the till on 12 May?” Bad: “Are you an honest person in general?” The fewer value judgements and assumptions, the more accurate the result.
How much polygraph examiner services cost — prices
The cost depends on the type of test, the number of topics, the format and the urgency. There are no hidden fees — the price includes preparing the tests, the testing itself and the final report.

Andriy Maryniak, polygraph examiner since 2012 · 6,000+ tests
Testing is done only with the voluntary written consent of the person being tested. Not sure which questions to ask? Ready-made test plans — from 590 UAH (≈ €12), credited towards the test.
How accurate the result is and whether a polygraph can be fooled
Accuracy depends on the method, correctly worded questions, the person’s condition (sleep, stress, alcohol) and the absence of pressure. “Life hacks from the internet” usually don’t work: an experienced polygraph examiner detects attempted countermeasures and reports them to the client.
How to prepare for the test
- Get a good night’s sleep the night before.
- Don’t drink alcohol for 24 hours before the test.
- Don’t come straight after a conflict.
- Tell the examiner about any medication or health conditions.
How to choose a polygraph examiner — a checklist
- Training as a “polygraph examiner” confirmed by a state-standard certificate.
- Legal equipment that meets the DSTU 8692:2016 standard.
- Experience and specialisation.
- Reputation and genuine reviews.
- Confidentiality and clear paperwork.
Legal status and confidentiality
Good polygraph examiner services rest on three rules: voluntary participation, confidentiality and a clear protocol. All data are the property of the client and are not passed on to third parties. A lawyer can use the conclusion as an additional check of the facts; for court, a separate forensic examination is needed.
