Lie Detector Test in Las Vegas, Nevada
Private, all-inclusive polygraph examinations at our Las Vegas office — conducted by examiners trained to APA standards. Fixed pricing from $560, no hidden fees, same-day results.
What Happens at Your Las Vegas Appointment
Every examination follows the same controlled procedure — from arrival to your written report. Here is exactly what to expect.
- Book online — select Las Vegas, pick your preferred date and time, and pay the $100 deposit
- Get confirmed — receive SMS and email confirmation with venue address, parking info, and directions within 24 hours
- Take your test — attend your 90-minute to 2-hour appointment with a APA-professional polygraph examiner
- Receive your report — get a detailed written report with methodology, question-by-question results, and examiner conclusions on the same day
Arrival & Check-In
What happens
You check in at the business centre reception under the name on your booking — there is no polygraph signage anywhere, for your privacy. Reception shows you to a private waiting area; your examiner meets you there and verifies your photo ID before anything begins.
Your part
- Bring a valid government photo ID and your confirmation
- Arrive rested — not rushed, not caffeinated
- A support person may wait in reception
Pre-Test Interview
What happens
Your examiner explains the entire procedure and the instruments, completes your consent paperwork, and conducts a psychophysiological suitability assessment — covering health, medication, and sleep. Then, together, you review and agree the exact wording of every test question. Nothing asked during the examination will be a surprise.
Your part
- Be open about medications and health conditions
- Raise anything you want asked — this is the moment
- Ask questions until you are fully comfortable
The Examination
What happens
Sensors are placed on your upper body and connected to a government-grade computerised instrument. You answer the agreed yes-or-no questions while four physiological channels are recorded. Each question is repeated a minimum of 3 times across multiple charts — a single reaction never decides a result.
What the instrument records
- Cardiovascular activity — heart rate & blood pressure
- Electrodermal activity — skin conductivity
- Thoracic & abdominal respiration
- Movement & timing, chart by chart
Analysis & Verbal Result
What happens
The examiner scores your charts using standardised numerical scoring, explains what the data shows, and discusses the preliminary outcome with you in the post-test review. You leave knowing your result — not waiting for a letter.
Your part
- Ask anything about how the result was reached
- Discuss next steps if the matter is ongoing
Your Written Report
What it contains
- The methodology and technique used
- Every question asked, verbatim
- The recorded physiological data
- The examiner’s professional conclusions
Confidentiality
Results are shared only with you unless you authorise otherwise in writing. Reports are suitable for attorneys and, where your matter requires it, prepared with legal proceedings in mind.
- Pre-test consultation (30–45 min) — all questions reviewed and agreed before the test begins
- Full polygraph examination — questions repeated minimum 3 times for accuracy using digital instruments
- Post-test review — examiner discusses preliminary findings with you
- Detailed written report — methodology, question-by-question results, physiological data, and professional conclusions
- Private testing venue — discreet, climate-controlled suite at 101 Convention Center Drive, Las Vegas, NV 89109
- Professional examiner trained to APA standards — vetted and experienced

Getting to the Las Vegas Office
The office tower at 101 Convention Center Drive has its own multi-level visitor garage — the 101 Convention Center Plaza Garage — at the same address, with drive-up rates from around $17; pre-booking via SpotHero is usually a little cheaper, and the small surface lot at 15 Debbie Reynolds Drive next door runs about $16.
Arriving without a car is easy: the building is a block off the Strip, and the RTC's Deuce bus on Las Vegas Boulevard stops a short walk away, as do Strip-corridor rideshare drop-offs.
Travelling Far? Arrive the Night Before
If your journey is more than about two hours, we strongly recommend travelling the evening before and staying near the office. A full night’s sleep is not just comfort — fatigue measurably affects the physiological responses the polygraph records, and a rested examinee produces a cleaner, more reliable chart. Book a morning appointment, sleep 7–8 hours, have a light breakfast, and arrive unhurried.
Travelling From a Nearby City?
This office regularly serves clients travelling from surrounding cities without a local examiner. Each entry below shows the distance, estimated driving time, and turn-by-turn directions from that city to our Las Vegas office at 101 Convention Center Drive, Las Vegas, NV 89109. Allow extra travel time on the day — arriving rushed can affect your physiological baseline.
How to Prepare
- Get a full night’s sleep — fatigue affects physiological responses and concentration
- Eat a light meal beforehand; the appointment lasts up to 2 hours
- Avoid excessive caffeine, energy drinks, and nicotine on the day
- Take prescribed medication as normal and tell your examiner what you take
- Wear comfortable clothing — sensors are placed on your upper body
What to Bring
- A valid government-issued photo ID — your identity is verified before testing
- Your booking confirmation
- Any relevant documents or case notes for your examiner
- A written list of the questions or concerns you want addressed
- Glasses or hearing aids, if you use them
What Not to Do
- × Do not drink alcohol or take non-prescribed drugs in the 24 hours before your test
- × Do not stop prescribed medication — changing your routine skews your baseline
- × Do not arrive sleep-deprived, unwell, or rushed
- × Do not attempt countermeasures — they are detectable and can invalidate your result
- × Do not bring children into the session; an adult support person may wait in reception
When Testing Cannot Go Ahead
- × If you are under the influence of alcohol or non-prescribed drugs on the day
- × If you are severely ill, exhausted, or in significant pain
- × If a medical condition makes testing unsuitable without physician clearance
- × If you are under 18, or required consent is missing
- × If the examiner’s case review finds the matter unsuitable — your $100 deposit is refunded in full

Why This Matters — What a Professional Examiner Looks Like
Polygraph Testing in Las Vegas — What to Know
The Convention Center Drive office puts professional testing within a few minutes of both the Strip and the older neighborhoods east of it, which shapes who walks through the door. Alongside valley residents, the location sees a steady flow of casino and resort employees clearing their names in internal disputes, out-of-state clients who have flown in specifically because a question could not wait, and couples for whom this city's around-the-clock rhythm has strained trust past the point of conversation.
Las Vegas produces some case types at volumes few cities match. Marriages here absorb unusual pressures — opposite shifts, an economy built on nightlife, and a social world where secrecy is easy — so infidelity examinations dominate the calendar. But the city's high-cash economy contributes its own docket: missing-money disputes between friends after a win, allegations between roommates or family members, and business partners in the valley's fast-growing construction and services sectors questioning where funds went.
A single-issue examination in Las Vegas is $560, and a couples booking, where both partners test on related questions, is $860. Every appointment is reserved with a $100 deposit, with the balance due on the day. Nevada's state licensing of examiners, unusual nationally, means testing here carries regulatory oversight on top of professional standards, and each examiner is matched to the client and case individually after booking.

Beware of Unqualified Examiners

Unfortunately, unqualified individuals operating without accreditation continue to damage the industry’s reputation and deliver unreliable results. Always verify your examiner graduated from an APA-approved school and uses validated testing protocols.
