📋 About the real exam
- Who runs the exams
- The Sonography Principles and Instrumentation (SPI) examination and the Abdomen (AB) specialty examination are administered by ARDMS, part of Inteleos. Passing both earns the Registered Diagnostic Medical Sonographer (RDMS) credential with an Abdomen specialty.
- A two-exam pathway
- You must pass SPI and the Abdomen exam within five years of each other, in either order. SPI covers about 110 questions in 2 hours. The Abdomen exam covers about 165 questions in 3 hours and includes hotspot questions where you mark a finding on an image.
- What SPI covers
- SPI is the physics foundation for every ARDMS credential: physics of ultrasound, instrumentation and transducers, image optimization, Doppler concepts, clinical safety, and quality assurance.
- What the Abdomen exam covers
- The AB exam tests abdominal anatomy, perfusion and function, pathology, vascular abnormalities, trauma, postoperative anatomy, abdominal physics, and clinical care and practice across the organs, vessels, and soft tissues of the abdomen.
- Scoring
- Both exams report pass or fail on a point scale of 300 to 700, and a score of 555 or better passes. The scale is not a percentage and is not curve-based.
- Results
- Inteleos posts your official result to your portal. A candidate count for these exams was not published in the sources consulted for this edition, so this app does not print one. This app cannot predict or influence your result.
Fees, formats and rules change — always confirm the final details on the official exam site before you apply.

Questions
- Is this the official exam?
- No. These are original practice questions in a study app. 3H TestPrep apps are study aids with original practice questions. They are not official exams, are not affiliated with any testing organization or government agency, and do not provide or replace any required education, training, or certification.
- Is it a subscription?
- No. One payment of $49 and it is yours to keep — no expiry, nothing renews. The only time-limited product we sell is the All-Access Pass (one year), and it never auto-renews.
- Will this make me pass?
- No app can promise that, and we will not pretend to. What we can give you is the whole question bank, an explanation for every answer, and a readiness score that shows exactly where you stand — the rest is your study, and we built this to make every hour of it count.
- How do I unlock the full app after buying?
- Your receipt email carries an unlock code (see Redeem a code). Type it into the app once — it works offline, and your free-trial progress stays.
