Polygraph Examination Services

Objective. Confidential. Professional.

SF Bay Polygraph provides professional polygraph examination services for private individuals, attorneys, investigators, and other referring professionals.
Serving San Francisco, San Mateo, the Peninsula, and the greater Bay Area.

What We Offer

Professional Polygraph Examination Services

Examinations use computerized polygraph instrumentation, established professional procedures, and validated testing techniques. Examinations elsewhere in California and in other states may also be arranged, subject to applicable licensing and legal requirements. 

Every case is different. Polygraph examinations are designed around a specific issue or clearly defined allegation rather than broad or vague questions. Testing is available in English, Russian, and Ukrainian – in the language you are most comfortable speaking.

How the Examination Process Works

01

Initial
Consultation

We begin with a brief phone consultation to discuss the circumstances, answer initial questions, and determine whether a polygraph examination may be appropriate. A 50% deposit is required to schedule the examination.

02

Examination Preparation

The relevant issue and scope of the examination are clearly defined, and proposed test questions may be discussed.

03

Pre-Test
Interview

The examiner explains the polygraph procedure, reviews informed consent, discusses relevant background information and the specific issue being examined, and reviews each test question to ensure the examinee fully understands its meaning.

04

Practice
Test

A brief practice test helps the examinee become familiar with the process and allows the examiner to confirm that clear, usable physiological data are being recorded.

05

Polygraph
Examination

Physiological responses are recorded using computerized polygraph instrumentation and established examination procedures.

06

Analysis &
Results

The collected data are analyzed using validated scoring methods and appropriate procedures. Results are then discussed and/or provided in a written report, depending on the circumstances of the examination.

Professional Polygraph Examination

About the Examiner

SF Bay Polygraph was founded by Nataliya Panchenko, MSW, LCSW, a formally trained polygraph examiner with a professional background in clinical interviewing and behavioral health.

Her clinical experience complements her polygraph training by providing extensive experience communicating about sensitive subjects, establishing professional rapport, and working effectively with individuals experiencing stress or anxiety.

SF Bay Polygraph

A Professional and Objective Approach

A polygraph examination should never begin with a predetermined conclusion.

Each examination is conducted neutrally and includes a pre-test interview, review of the issue and examination questions, physiological data collection, analysis, and discussion or reporting of results as appropriate.

Informed consent is obtained before testing, and all test questions are reviewed with the examinee before physiological data are recorded. Those principles follow current American Polygraph Association (APA) standards.

Attorneys & Investigators

SF Bay Polygraph welcomes referrals from attorneys, private investigators, and other professionals seeking an independent examination related to a clearly defined issue.

Cases are approached objectively, with attention to professional documentation, confidentiality, and the needs of the referring professional.
