Private polygraph test
A private polygraph examination is for personal certainty — infidelity and trust, family matters, private disputes. It is fully confidential and carried out only with the voluntary consent of the person examined.
When people come to us
Usually at a difficult moment — doubt in a relationship, an accusation to answer, a need to clear the air. We handle it discreetly and honestly. On the most sensitive case, see lie detector for infidelity.
How the examination works
- Pre-test interview — every question reviewed, no surprises.
- Measurements — reactions recorded on multi-channel equipment.
- Analysis and report — signed report within 24–48 hours.
An unclear recording is reported as inconclusive rather than forced — see what inconclusive means.
