GI Exam Domains 2026: Complete Guide to All 5 Content Areas

How the GI Assessment Is Built

Before dissecting the content areas, it helps to understand what the POCUS Gastrointestinal certification actually measures. The credential is issued by the Point-of-Care Ultrasound Certification Academy, part of Inteleos, and it has two components that must both be passed: a Clinical Case Assessment and a Peer Evaluation. The five domains discussed in this guide belong only to the first component. They are the official weighted objectives of the Clinical Case Assessment, drawn from the program's Gastrointestinal Content Outline, and they total 100% for that assessment, not for the entire credential.

The case assessment consists of 5 simulated clinical cases. That number describes cases, not questions. Within each case, you will meet multiple-choice questions and interactive image-hotspot questions, where you identify a structure or finding directly on an ultrasound image. The issuer has not published a fixed total question count or numeric passing mark in the public sources, so be wary of any site that quotes one. If you want the current state of what is and is not publicly known, see our breakdown of the GI passing score and the discussion in what the data shows about the GI pass rate.

The Five Domains at a Glance

The outline is a one-page document with no printed revision date or examination version, so treat it as the current program-linked scope rather than a dated edition. The "2026" in this article's title marks our editorial update, not a new issuer exam release.

Notice the shape of this distribution. Two domains carry two thirds of the weight, and the domain named "Pathologies" carries the least. That surprises many candidates, who assume a gastrointestinal exam is mostly about naming diseases. In reality, the outline rewards the reasoning chain: see the anatomy, describe the sonographic abnormality, then reach (or decline to reach) a diagnosis. For a deeper look at difficulty, our guide on how hard the GI exam really is covers what makes the case format demanding.

Domain 1: Standard POCUS Views (5%)

At 5%, this domain is easy to under-study, and that is a reasonable trade-off if you are already comfortable scanning. But do not skip it entirely. Questions about views often hide inside case stems: you may be shown an image and asked, implicitly, whether it is the right window for the clinical question. A candidate who cannot tell a standard view from a compromised one will struggle with the hotspot questions in later domains.

Because the Peer Evaluation also scores "Views" as one of its seven criteria, view acquisition pays off twice: once in the case assessment and once in how your peers rate your real scanning. We cover that second component below.

Domain 2: Anatomical Features (25%)

The strategic point about Domain 2 is that normal anatomy is the baseline against which every abnormality is judged. You cannot recognize a thickened wall without knowing what a normal wall looks like, and you cannot call fluid "free" without knowing where it should and should not be. Candidates who spend their time memorizing pathology images but never build a mental atlas of normal tend to lose points here and in the two heavy domains that follow.

Study this domain with paired images: a normal image alongside an abnormal image of the same region. Training your eye on the contrast is more efficient than studying either in isolation. Our GI study guide for passing on your first attempt lays out resource options for building this image bank.

Domains 3 and 4: Sonographic Findings and Diagnostic Findings (33% Each)

Together these two domains make up 66% of the Clinical Case Assessment. They are where most candidates win or lose the exam, and they test different skills that are easy to blur together.

Domain 3: Sonographic Findings (33%)

Domain 4: Diagnostic Findings (33%)

The distinction matters. A sonographic finding is an observation ("a non-compressible, blind-ending tubular structure"); a diagnostic finding is a conclusion ("findings consistent with appendicitis in this clinical context"). The case format lets the examiners probe both: a hotspot question may ask you to locate the abnormality, and a following multiple-choice question may ask what it means.

Here is an original teaching example, not an exam item. A patient presents with abdominal distension and vomiting. Your images show dilated, fluid-filled loops. A strong candidate describes the loops (Domain 3), then reasons about whether the pattern is consistent with obstruction in this clinical setting, and what features would push toward or away from that conclusion (Domain 4). A weak candidate memorizes "dilated loops equals obstruction" and misses the cases where the same appearance has another explanation.

Domain 5: Gastrointestinal Pathologies (4%)

Two observations. First, the list includes "no sonographic abnormalities," a reminder that a normal study is itself a legitimate answer. Second, because the list is explicitly non-exhaustive, you should not assume any entity outside it is out of bounds. Study these eight thoroughly, then build general pattern-recognition skills that transfer to presentations not named on the outline.

Although Domain 5 is only 4% by weight, the pathologies it names are the raw material for the cases in Domains 3 and 4. You will meet them through the case scenarios, which is why the weight on this heading understates how much pathology knowledge you actually need. The practical consequence: learn pathologies as image patterns and clinical stories, not as a flat list to recite.

The Peer Evaluation: Seven Criteria, Separate From the Domains

The second required component is a Peer Evaluation that assesses your practical scanning abilities. It has 7 evenly weighted criteria:

1. Diagnostic Quality
2. Gain
3. Depth
4. Views
5. Compression
6. Pathology
7. Color Doppler

These criteria do not add to the domain count. The credential has five content domains and, separately, seven peer-evaluation criteria. Mixing them up is a common mistake in third-party prep material.

The evaluation is done by healthcare-provider peers with an ultrasound clinical background who know your scanning abilities; you must provide at least two. The first two completed peer questionnaires determine the peer result. Eligibility also asks you to attest to performing and participating in the interpretation of at least 25 gastrointestinal POCUS cases within the preceding two years. Full details are in our guide to GI requirements and how to qualify.

Scheduling Your Prep by Domain Weight

Generic study plans ignore the weights. A GI-specific plan should allocate time roughly in proportion to them while front-loading the foundation that everything else depends on. Here is one way to structure a four-week approach tied to the outline:

The logic: Weeks 1 and 2 build perception, Week 3 builds judgment, and Week 4 combines them. Putting the two 33% domains in the middle of the plan, after the foundations are solid, mirrors how the content actually builds. If you want a compressed reference once you have studied, the GI cheat sheet is a good last-pass review, and you can test yourself with our GI practice tests.

Logistics That Shape How You Study

A few mechanics from the program affect how you pace your preparation:

• Delivery: The assessment is administered online through myPOCUS and its learning management system. A confidentiality and nondisclosure agreement is required.
• Completion window: Both components must be completed within 90 days of purchase. This is an access and completion window, not a timed sitting or a course-hour requirement. The FAQ permits stopping and resuming online assessments.
• Fees: The standard clinical certification fee is USD 150, with reductions for eligible countries. POCUS Fundamentals, when required, carries a separate USD 125 fee; the combined initial total is USD 275 only when both must be purchased, excluding optional courses. See the full GI certification cost breakdown.
• Fundamentals prerequisite: POCUS Fundamentals is required unless waived for an SPI examination passed within 5 years or a current qualifying ARDMS or APCA credential.
• Retakes: There are two total content-specific assessment attempts before a one-year waiting period, with a 30-day wait after an unsuccessful attempt. Apply for a retake within 90 days of failure; any initially passed component is retained for the first retake application. A retake fee applies, though the amount was not verified.
• Validity and renewal: The certification is valid for 5 years. Renewal involves an active-practice and good-standing attestation, a knowledge check, and a USD 50 fee.

If you are weighing the investment, our analyses of whether the GI certification is worth it and the role-based GI salary guide stay within what the evidence supports: they do not promise a credential-specific pay increase. For timing questions, see GI exam dates and scheduling.
