CLT-LANA Exam Domains 2026: Complete Guide to All 4 Content Areas

TL;DR
  • The LANA exam has four domains; Domains 2 and 4 each carry 30% of content.
  • Domain 1 (Anatomy and Physiology) is 25%, and Domain 3 (Patient Evaluation and Treatment Planning) is 15%.
  • The exam has 130 four-option questions: 110 scored plus 20 unidentified research items, in 150 minutes.
  • Passing requires a scaled score of 700 out of 1000, not 70% raw accuracy.

The CLT-LANA Blueprint at a Glance

The LANA Certified Lymphedema Therapist credential, abbreviated CLT-LANA, is awarded by the Lymphology Association of North America. Its exam does not sample the field evenly. The content outline divides everything a certified therapist is expected to know into four domains, and the weighting tells you where the questions come from. If you are still sorting out what the credential is and who awards it, start with What Is CLT-LANA? and then return here for the content breakdown.

This guide walks through each domain using the exact domain names on the content outline, explains what each one demands in practical terms, and shows how to turn the weights into a study plan. It is written by an independent exam-preparation resource and is not affiliated with LANA or its testing partners.

DomainNameWeight
1Anatomy and Physiology25%
2Lymphedema, Vascular, and Related Disorders30%
3Patient Evaluation and Treatment Planning15%
4Management of Lymphedema and Related Disorders30%

Notice the shape of that table. Two domains are tied for the largest share, one is a quarter of the exam, and one is a comparatively small 15%. A common mistake among candidates who have completed their coursework is to study in proportion to how much classroom time each topic received. Course time and exam weight are not the same thing, so build your plan from the weights instead.

How 110 Scored Questions Map to the Four Domains

The exam contains 130 multiple-choice questions, each with four options and a single correct answer. Of those, 110 are scored and 20 are unidentified research items. You cannot tell which are which, so every question deserves full effort. You have 150 minutes of testing time, which works out to a little over a minute per question if you spend it evenly.

Because only the 110 scored items count, the domain weights apply to that scored portion. As a rough planning aid, 30% of 110 is about 33 questions each for Domains 2 and 4, 25% is about 27 or 28 questions for Domain 1, and 15% is about 16 or 17 for Domain 3. Treat these as approximations for planning, not as a guaranteed count on your particular form.

Scaled score, not raw percentage: The passing standard is a scaled score of 700 out of 1000. That is not the same as answering 70% of questions correctly. Scaled scoring adjusts for differences between exam forms, so do not convert your practice-test percentages directly into a predicted result. For more on this, see CLT-LANA Passing Score 2026: Exactly What You Need to Pass.

Domain 1: Anatomy and Physiology (25%)

Anatomy and Physiology is the foundation on which every later domain rests. At 25%, it is roughly a quarter of the scored exam, and it also underpins questions that appear to belong elsewhere. A question about why a particular compression approach is chosen, for example, often turns on understanding fluid dynamics in the tissues.

Domain 1: Anatomy and Physiology

Candidates must understand the structure and function of the lymphatic system and how it interacts with the circulatory system and surrounding tissues.

  • Lymphatic vessel hierarchy: initial lymphatics, precollectors, collectors, trunks, and ducts
  • Lymph nodes, their distribution, and regional drainage territories
  • Watersheds and anastomoses, and how they support alternate drainage pathways
  • Capillary filtration and reabsorption, including the forces that govern fluid movement
  • Composition and formation of lymph, and the role of proteins in tissue fluid balance
  • Lymphatic load, transport capacity, and the concept of safety valve function
  • Venous and arterial anatomy relevant to limb and trunk drainage
  • Skin and subcutaneous tissue structure

Where candidates lose points here

The most common weakness is memorizing structures in isolation rather than as a functioning system. Expect questions that ask you to reason from a drainage territory to a clinical consequence: if a particular node region is compromised, which area is at risk of congestion, and which alternate pathway could compensate? Practice tracing flow from the periphery to the venous angle until you can do it without notes.

Domain 2: Lymphedema, Vascular, and Related Disorders (30%)

Domain 2 shares the top weight with Domain 4, and it is the broadest in subject matter. The domain title itself signals the breadth: it covers primary and secondary lymphedema, fat disorders, and arteriovenous disease, along with related conditions that can mimic or coexist with lymphedema. Candidates who treat this as a simple "types of lymphedema" topic are underestimating it.

Domain 2: Lymphedema, Vascular, and Related Disorders

This domain tests whether you can recognize, differentiate, and understand the pathophysiology of the conditions you will encounter in clinical practice.

  • Primary lymphedema: congenital, praecox, and tarda presentations, and associated genetic considerations
  • Secondary lymphedema: causes such as cancer treatment, surgery, radiation, trauma, infection, and chronic venous disease
  • Fat disorders, including lipedema, and how they differ from lymphedema in presentation and behavior
  • Chronic venous insufficiency and venous disease, and the overlap with lymphatic dysfunction
  • Arterial disease and its implications for treatment safety
  • Staging and classification systems for lymphedema
  • Complications such as cellulitis, fibrosis, and skin changes
  • Other causes of swelling and conditions that must be distinguished from lymphedema

Differentiation is the core skill

Much of this domain comes down to telling similar conditions apart. A candidate should be able to compare lymphedema, lipedema, and venous edema by distribution, symmetry, skin findings, and response to elevation. Building comparison tables for these conditions is one of the highest-value study activities you can do, and the exam rewards that kind of structured knowledge. Arteriovenous disease also matters for safety: you need to know when vascular status changes what is appropriate in treatment.

Why 30% deserves respect: Together with Domain 4, this domain accounts for 60% of the scored content. A candidate who is strong in anatomy but shaky on related disorders can still struggle overall. Give Domain 2 early, repeated attention rather than saving it for the end.

Domain 3: Patient Evaluation and Treatment Planning (15%)

Patient Evaluation and Treatment Planning is the smallest domain at 15%, but it connects the knowledge in Domains 1 and 2 to the interventions in Domain 4. Candidates sometimes skim it because of its weight, which is a mistake: the reasoning skills it tests show up inside scenario questions throughout the exam.

Domain 3: Patient Evaluation and Treatment Planning

This domain covers how a therapist gathers information, interprets findings, and builds a plan appropriate to the individual patient.

  • Patient history, including medical, surgical, oncologic, and medication history
  • Physical assessment: inspection, palpation, skin and tissue quality
  • Limb measurement methods and how to track change over time
  • Recognizing contraindications, precautions, and red-flag findings that require referral
  • Setting realistic goals and prioritizing problems
  • Selecting and sequencing interventions based on stage, comorbidities, and patient circumstances
  • Considering the patient's ability to self-manage, home environment, and support

Questions here tend to be scenario-driven. You may be given a short patient description and asked what the most appropriate next step is, or which finding should prompt caution or referral. The skill being tested is judgment, so practice explaining why an option is right and why the other three are wrong.

Domain 4: Management of Lymphedema and Related Disorders (30%)

Domain 4 is the other 30% pillar, and it covers what a therapist actually does. This is where the technical content of complete decongestive therapy (CDT) lives. Because eligibility for the exam requires qualifying CDT training, you have likely practiced many of these skills, but the exam tests whether you can explain and apply them correctly and safely.

Domain 4: Management of Lymphedema and Related Disorders

This domain tests the rationale, technique, and safe application of treatment for lymphedema and the related conditions covered in Domain 2.

  • Components of CDT and the purpose of each phase
  • Manual lymph drainage principles, sequencing, and when modifications are needed
  • Compression bandaging: materials, layering, pressure principles, and when each approach applies
  • Compression garments: selection, fitting concepts, and replacement considerations
  • Therapeutic exercise and its role in promoting lymphatic return
  • Skin and nail care and infection prevention
  • Patient education for long-term self-management
  • Maintenance phase planning and managing flare-ups or setbacks
  • Adapting management for related disorders and for patients with complicating conditions
  • Modifying or withholding techniques when contraindications are present

Know the why, not just the how

Candidates with strong hands-on training sometimes stumble because the exam asks about rationale and safety, not technique alone. Be prepared to explain why a bandaging layer is chosen, what the phases of CDT are intended to accomplish, and how management changes when a patient has a complicating condition. If your training covered the practical skills well, convert that knowledge into verbal explanations; a good test is to describe a technique and its rationale aloud as if teaching a colleague.

What the Questions Look Like

Every question is multiple choice with four options and one best answer. The exam is closed book and given in English. Beyond that, the questions vary in how they ask for knowledge.

  • Recall questions ask for a definition, structure, or fact, mostly from Domains 1 and 2.
  • Comparison questions ask you to distinguish between similar conditions or techniques.
  • Scenario questions describe a patient and ask for the best action, finding, or next step, most common in Domains 3 and 4.
  • Safety questions test whether you recognize a contraindication or precaution before acting.

Because only one answer is correct, the distractors are usually plausible. They often describe something that would be reasonable in a different situation but is wrong for the one presented. Read the stem for qualifiers such as "most appropriate," "first," or "contraindicated," and eliminate options that fail the specific conditions given.

Key Takeaway

Do not study as if the exam were only recall. Roughly the second half of the blueprint rewards clinical reasoning. Pair every fact you memorize with a scenario in which you would use it.

Sequencing Your Preparation Around the Weights

You do not need an elaborate method here, just a sensible order. The domains build on one another, so a plan that follows that dependency, while giving the heaviest domains the most time, works well. A general walkthrough of preparation habits is in the CLT-LANA Study Guide 2026: How to Pass on Your First Attempt; the schedule below is specific to the blueprint.

Weeks 1-2

Domain 1: Anatomy and Physiology

  • Rebuild the drainage pathways and territories from memory
  • Review filtration, reabsorption, and lymphatic load concepts
  • These concepts will support everything that follows
Weeks 3-5

Domain 2: Lymphedema, Vascular, and Related Disorders

  • Build comparison tables for lymphedema, lipedema, and venous conditions
  • Study staging, complications, and arteriovenous considerations
  • Spend the most time here because of its breadth and 30% weight
Week 6

Domain 3: Patient Evaluation and Treatment Planning

  • Work through assessment and contraindication scenarios
  • Practice explaining why you would refer or modify
Weeks 7-8

Domain 4: Management, then mixed review

  • Review CDT components, bandaging rationale, and maintenance planning
  • Finish with mixed-domain practice under timed conditions

Adjust the timeline to your own background. A therapist fresh from a CDT course may need less time on Domain 4 and more on Domain 1 or 2, while someone with a long clinical history may be the reverse. Use a diagnostic practice set on the CLT-LANA practice test site to find your weakest domain before committing to a schedule. For a compact last-pass review, the CLT-LANA Cheat Sheet 2026: One-Page Review of Must-Know Facts is useful in the final days.

Exam Logistics That Shape Your Domain Strategy

Knowing the domains is only part of readiness. A few mechanical details influence how you prepare and when.

  • Format and timing: 130 questions in 150 minutes. Pace yourself so that no single hard question consumes time you need elsewhere.
  • Delivery: Prometric supports exam administration through test centers and approved remote-proctored delivery. The candidate booklet uses IQT scheduling terminology, so look for that wording when you schedule.
  • Fee: The exam fee is $430, increasing to $480 on April 1, 2027. Details are in CLT-LANA Certification Cost 2026: Complete Pricing Breakdown.
  • Retakes: A six-month wait applies between attempts, with a maximum of three attempts in 24 months, followed by an additional 12-month wait after three failures. This makes a thorough first attempt worth the extra preparation.

Eligibility requirements also tie directly to the domain content. Candidates need an accepted professional license, registration, or equivalent qualifying credential; at least 135 hours of qualifying CDT training with an in-person skills assessment; and 12 college science credit hours, with specified professional-licensure exemptions. LANA's April 2026 policy permits remote theoretical instruction but requires on-site practical laboratory instruction. Review CLT-LANA Requirements 2026: Eligibility, Prerequisites & How to Qualify to confirm you qualify before you build a study schedule, and see CLT-LANA Exam Dates 2026: Testing Windows, Deadlines & Scheduling for scheduling.

Practice material note: Use original practice questions written to the four-domain structure rather than anything claiming to be recalled live exam content. Reputable preparation focuses on building understanding of the blueprint, not on memorizing leaked items. This site is independent exam preparation and is not affiliated with LANA.

Why Domain Mastery Matters Beyond Test Day

The four domains mirror the work. Anatomy and Physiology explains the mechanism, Lymphedema, Vascular, and Related Disorders defines what you are treating and what you must rule out, Patient Evaluation and Treatment Planning is the clinical reasoning, and Management of Lymphedema and Related Disorders is the intervention itself. Employers who hire certified lymphedema therapists, such as outpatient rehabilitation clinics, hospital oncology and wound programs, and dedicated lymphedema practices, are looking for exactly this combination.

If you are weighing whether the credential fits your career direction, the Is the CLT-LANA Certification Worth It? Complete ROI Analysis 2026 and CLT-LANA Jobs articles cover the practical side. Once certified, the credential renews every six years through 24 contact hours of qualifying education or other approved activities, or re-examination, with a current qualifying professional credential and a renewal fee. Recertification costs $200, increasing to $250 on January 1, 2027.

When you are ready to test your knowledge against all four domains under realistic conditions, take a timed set on the CLT-LANA Exam Prep practice tests and review your results by domain rather than by overall score alone.

Frequently Asked Questions

Which CLT-LANA exam domains are weighted most heavily?

Domain 2 (Lymphedema, Vascular, and Related Disorders) and Domain 4 (Management of Lymphedema and Related Disorders) are jointly the largest at 30% each. Together they make up 60% of the content, so they should receive the largest share of your study time.

How many questions are on the exam, and how many are scored?

The exam has 130 four-option, single-answer multiple-choice questions. Of those, 110 are scored and 20 are unidentified research items. You have 150 minutes, and since you cannot tell which items are unscored, answer every question carefully.

Do I need 70% correct to pass?

No. Passing requires a scaled score of 700 out of 1000, which is not the same as 70% raw accuracy. Scaled scoring accounts for differences between exam forms, so practice-test percentages are only a rough guide to readiness.

Is Domain 3 safe to study lightly because it is only 15%?

It carries the smallest weight, but the evaluation and treatment-planning reasoning it tests appears inside scenario questions across the exam. Study it efficiently rather than skipping it, and pay particular attention to contraindications and referral decisions.

What happens if I do not pass on my first attempt?

A six-month wait applies before a retake, and you are allowed a maximum of three attempts in 24 months, followed by an additional 12-month wait after three failures. Reviewing your performance by domain helps you target the weak areas before trying again. For data on outcomes, see CLT-LANA Pass Rate 2026: What the Data Shows.
