# Lie Detector Test > Professional polygraph (lie detector) examinations across the United States, Canada and the United Kingdom. Confidential, in-person testing by carefully vetted examiners trained to APA standards, with professional office locations, transparent all-inclusive pricing, and detailed written reports. Lie Detector Test (LieDetectorTest.com) arranges in-person polygraph examinations nationwide. Bookings are made online: the client chooses a location, service and preferred dates, agrees the terms, pays a booking-fee deposit, and completes a short confidential pre-examination assessment. Every case is individually reviewed by a specialist before it is accepted, and an examiner is then assigned to the client and case. If a case cannot be accepted or a suitable date cannot be agreed, the deposit is refunded in full. The booking-fee deposit is $100 (USD/CAD) or £150 in the United Kingdom, deducted from the total examination price; the balance is paid directly to the examiner. ## Key pages - [Book a test](https://liedetectortest.com/bookings): Guided online booking — location, service and dates, terms, deposit, and the pre-examination assessment. - [Pricing](https://liedetectortest.com/prices): All-inclusive examination prices by location and service type. - [Locations](https://liedetectortest.com/locations): Professional test locations across the US, Canada and the UK; find the nearest office. - [FAQ](https://liedetectortest.com/faq): Accuracy, procedure, confidentiality, preparation and what to expect. - [About us](https://liedetectortest.com/about-us): Who we are, examiner vetting, and testing standards. - [Contact](https://liedetectortest.com/contact): Get in touch with the team. ## Services - [Private lie detector tests](https://liedetectortest.com/private-lie-detector-test): Personal and relationship matters such as infidelity and trust issues. - [Legal defense polygraph services](https://liedetectortest.com/legal-defense-polygraph-services): Examinations conducted for legal and defense purposes. - [Polygraph testing for therapy practices](https://liedetectortest.com/lie-detection-for-therapy-practices): Testing that supports therapy and treatment programs. ## Learn - [Learning center](https://liedetectortest.com/learning-center): Articles on polygraph testing, accuracy and the examination process. ## For AI agents & developers - **MCP server** (Model Context Protocol): `https://liedetectortest.com/wp-json/ldt-mcp/v1/mcp` — Streamable HTTP, JSON-RPC 2.0.
