Lie Detector Test USA — UK P300 EEG Examiner Flown In
Independent P300 EEG brain-wave lie detection across the United States — delivered by a UK-qualified examiner with no affiliation to any US polygraph firm, law enforcement agency or employer. We fly directly to you with 8-channel EEG equipment and conduct your test in a private, confidential venue in any major US city with 95% accuracy.
Brain-Wave Testing. Not Sweat & Heart Rate.
The vast majority of lie detector tests in the USA still rely on the traditional polygraph — measuring breathing, pulse and skin conductivity the same way it has for nearly a century. We bring something different: an 8-channel EEG that measures a brain-wave called the P300, which fires involuntarily when your brain recognises a detail it already knows.
Traditional Polygraph
- Measures anxiety symptoms — not truth directly
- Heavily affected by nerves, anger, stress
- Countermeasures documented widely online
- Accuracy ~85-89% on single-issue tests
- Subjective chart interpretation
- Widely available across the USA already
P300 EEG (What We Do)
- Measures brain recognition — not emotional state
- Involuntary neural response — hard to suppress
- Countermeasures don't block P300 spikes
- 95% accuracy on guilty-knowledge protocols
- Objective waveform analysis
- Independent UK examiner — not tied to any US agency
Built for America's Most Common Private Cases
We see the same patterns of demand that established US polygraph providers describe — with the added benefits of an independent UK-qualified examiner, P300 EEG brain-wave technology, and no affiliation to any US law enforcement, employer or adversarial party in your case.
Specific-Incident Corporate Investigations
Ongoing investigations of specific economic loss — theft, fraud, data leaks, insider sabotage, expense abuse — conducted with written employee consent in line with the US Employee Polygraph Protection Act (EPPA). Volume discounts for 3+ tests.
Relationship & Infidelity
Private, discreet testing for cheating allegations, emotional affairs, messaging history disputes, or to verify a partner's statements before trust is rebuilt. Confidential venue, results same day.
Legal & Civil Disputes
Civil claims, family law, pre-nuptial verification, business partner disputes, estate & inheritance disagreements, and matters requiring consenting-parties testing. Written report suitable for private legal use.
Second Opinion / Pre-Police
For individuals asked to take a law-enforcement or defense-related polygraph, or those who previously failed a traditional polygraph and want an independent P300 EEG test on the same facts to support their position.
Executive & Self-Elective
Senior hire verification (where EPPA exemptions apply), executive self-elective testing, domestic & personal-staff vetting for private households, and family office screening. Always voluntary, always with written consent.
False Accusations
If you've been accused of theft, dishonesty or misconduct at work or in your personal life, a passed P300 EEG test provides objective evidence of your truthfulness that traditional polygraph cannot match.

Questions We Get From US Clients
Yes. A UK-qualified examiner flies to the USA with our 8-channel P300 EEG equipment. Tests are conducted in a private, confidential venue in any major US city — typically a reserved hotel suite in New York, Los Angeles, Chicago, Miami, Houston, Washington DC, Dallas, Boston or San Francisco — or at your corporate premises for company cases.
Traditional polygraph measures anxiety — breathing, heart rate, sweat. P300 EEG measures a specific brain-wave that fires involuntarily when your brain recognises a detail you've seen or done before. It's measurably more accurate, not defeated by common countermeasures, and not distorted by nervousness. Most US polygraph examiners use the traditional technology — our UK-qualified examiner brings P300 EEG as an independent alternative.
Admissibility varies significantly by US state and circumstance. New Mexico admits polygraph evidence under certain conditions; most other states admit it only by stipulation of both parties; federal courts apply the Daubert standard and typically exclude it. Our service is primarily used privately — to support internal corporate investigations, HR matters, civil disputes, family and relationship resolution, and as investigative evidence rather than formal trial evidence. Speak to your attorney about admissibility in your specific jurisdiction.
Strictly confidential. Tests take place in private booked venues. Reports are issued only to the paying client. We operate under UK data protection standards (UK GDPR) and do not share, store or disclose any case information to third parties without written instruction.
This is one of our most common US enquiry types. Traditional polygraph results can be distorted by nerves, medication, medical conditions, or simply poor question design. A P300 EEG test on the same underlying facts measures something different — brain recognition rather than anxiety — and can provide a clear, independent result to support your position.
Yes, within the limits of the US Employee Polygraph Protection Act (EPPA). EPPA permits employee testing in specific circumstances — ongoing investigations of identified economic loss, with written employee consent, and where certain notice requirements are met — as well as exemptions for security firms and controlled-substance handlers. We work only on cases that fit these parameters. Our Corporate Package is designed for group investigations of 3-10 employees on a single visit. Per-test rates reduce significantly with volume. You should verify your specific case qualifies under EPPA with your employment attorney before booking.
We accept USD or GBP payment via international bank transfer, Wise, or major international credit cards. All invoices are issued by DadLink Technologies Limited (UK). Deposit is required to confirm the booking; balance is due before the test begins.
Tests are conducted in English. If the subject needs a Spanish or Mandarin interpreter, we can arrange one locally — please raise this at the enquiry stage so we can factor it into scheduling.
