Minnesota's polygraph testing service is anchored in the Twin Cities metropolitan area — Minneapolis and Saint Paul — serving the state's largest population centre and surrounding communities. Our APA-certified examiners provide professional, confidential examinations in controlled-environment offices.
Minnesota's polygraph services address the needs of a state known for its strong consumer protections and high professional standards. Our examiners understand Minnesota's specific statutory restrictions on workplace polygraph use and provide examinations that fully comply with both federal and state law.
All prices are all-inclusive — covering the booking fee, examination, pre-test assessment, and a fully detailed report. Only a $100 booking fee is required upfront. The remaining balance is due after your case is reviewed and accepted by the examiner.
Lie Detector Test Prices in Minnesota
A lie detector test in Minnesota costs between $550 and $550 depending on location. All prices are all-inclusive, covering the booking fee, APA-certified examiner, private office, pre-test assessment, full polygraph examination, and a detailed written report. Only a $100 refundable deposit is required to book — you only pay the balance once your case is reviewed and accepted.
Single Examination
One person tested on a single issue. The standard polygraph examination — ideal for personal matters, legal support, or clearing your name.
Couple Testing
Both partners tested on the same day in the same session. Each person undergoes a separate, private examination on an agreed set of questions. The price is all-inclusive for both people.
Group Testing (3+)
Three or more individuals tested separately in succession. Per-person rate — commonly used for workplace theft, family disputes, or legal cases involving multiple parties.
Booking requires just a $100 deposit. Your examiner reviews every case before the test to confirm suitability — not every situation is appropriate for polygraph testing, and we'd rather tell you upfront than take your money. The balance is due only after your case is accepted. If it's not suitable, your deposit is returned in full.
Not Every Lie Detection Service Advertised in Minnesota Is Legitimate
Read this if you're looking for any lie detection service in Minnesota. It could save you time, money, and a lot of unnecessary stress.
If you're searching for a lie detector test in Minnesota for the first time, you're probably facing an important decision
— whether it involves a relationship, a legal matter, or a professional dispute. The result of your polygraph test may shape what happens next, so the accuracy and legitimacy of the service you choose genuinely matters.
Unfortunately, not every company advertising "lie detection" in Minnesota is offering a scientifically validated service. Some use unproven alternative techniques — voice stress analysis, EEG-based methods, or eye-tracking — that have no peer-reviewed research confirming their accuracy. Others may use real polygraph equipment but employ unqualified or uncertified examiners who haven't completed accredited training. These shortcuts produce unreliable results that can lead to the wrong conclusions at the worst possible time.
Here's what a legitimate polygraph service looks like: a computerized polygraph instrument operated by an examiner who graduated from an APA-accredited school, completed a supervised internship, passed background and criminal history checks, and holds any required state licence.
While Minnesota does not require a separate state polygraph licence, our examiners still meet the same rigorous standards we enforce across our entire network — as defined in our Standards of Practice.
Certified examiners are also required to complete a minimum of 30 hours of continuing education every two years to stay current with evolving research and methodology. Every examiner in our network meets these requirements — we verify credentials independently, conduct ongoing quality reviews, and require full adherence to our Code of Ethics and Standards of Practice. Under these conditions, peer-reviewed research confirms accuracy rates of up to 95% for single-issue examinations.
Ask if the examiner is APA-accredited — if they can't confirm, walk away
Verify they use a computerized polygraph — not voice analysis or alternatives
Check their continuing education — 30 hours every 2 years is the standard
Request a written report with scoring — credible examiners always provide one
Every examiner is a member of the American Polygraph Association (APA)
