Is it possible to repeat a test to be on the safe side? Although this is possible, it is not necessary as the results are usually almost beyond doubt. Further rounds usually confirm the result. Would you also like to catch the target in the act, keep his lies in front of you and confront him with facts? There are people who lie almost pathologically and narcissistically stick to their made-up stories even when all the evidence speaks against them. These can be very manipulative people who trick other people with their lies over and over again. In combination with a detective or a decoy, we expand our range of possibilities enormously. We would be happy to advise you free of charge by telephone.
