What the CLT-LANA Credential Actually Is
CLT-LANA stands for LANA Certified Lymphedema Therapist. It is a professional certification awarded by the Lymphology Association of North America (LANA) to clinicians who have completed qualifying complete decongestive therapy (CDT) training and demonstrated their knowledge on a standardized examination. The letters after a therapist's name signal that the holder has met LANA's education requirements, passed a closed-book exam, and maintains the credential through ongoing education.
If you are still sorting out terminology, our short explainers cover the basics from several angles: What Is CLT-LANA?, What Does CLT-LANA Stand For?, and CLT-LANA Meaning. This article goes a step further and explains how the certification works in practice: who qualifies, what the exam looks like, what it costs, and how to prepare for the content that carries the most weight.
Who Awards It and How the Exam Is Delivered
LANA is the certifying body. Prometric supports exam administration, and candidates can test either at a test center or through approved remote proctoring. LANA's candidate information booklet uses IQT scheduling terminology, so if you see that abbreviation while booking, it refers to the scheduling process for the exam rather than a separate credential or step.
The exam is administered in English and is closed book. You will not have access to reference charts, notes, or textbooks during testing, which means anatomy, pathophysiology, and treatment principles must be firmly in memory rather than something you know how to look up. For a look at timing and logistics, see CLT-LANA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
The Three Eligibility Pillars
Eligibility is where many candidates stumble, because the requirements are cumulative and each must be documented. In summary, you need all three of the following:
1. A Qualifying Professional License, Registration, or Credential
LANA requires an accepted professional license, registration, or equivalent qualifying credential. This is also a continuing requirement: renewal depends on holding a current qualifying professional credential.
2. At Least 135 Hours of Qualifying CDT Training
Your training must be qualifying complete decongestive therapy education totaling at least 135 hours, and it must include an in-person skills assessment.
- Manual lymphatic drainage technique
- Compression bandaging and garment fitting
- Skin and nail care, exercise, and self-management instruction
3. 12 College Science Credit Hours
Candidates must show 12 college science credit hours, with specified exemptions for certain professional licensure categories. Check the current candidate booklet to see whether your license falls under an exemption before assuming you need additional coursework.

Exam Format: 130 Questions, 150 Minutes, 700 of 1000
The exam consists of 130 four-option, single-answer multiple-choice questions. Of those, 110 are scored and 20 are unidentified research items, meaning LANA is piloting new questions and you cannot tell which ones they are. Treat every question as if it counts. You have 150 minutes of testing time, which works out to roughly 69 seconds per question if you spread your time evenly across all 130.
| Exam Feature | Detail |
|---|---|
| Total questions | 130 (four-option, single-answer multiple choice) |
| Scored questions | 110 |
| Unidentified research items | 20 |
| Testing time | 150 minutes |
| Passing standard | Scaled score of 700 out of 1000 |
| Reference materials | None (closed book) |
| Language | English |
| Delivery | Prometric test center or approved remote proctoring |
Why a Scaled Score Matters
The passing mark is a scaled score of 700 out of 1000. It is not 70% raw accuracy. Scaled scoring adjusts for differences in difficulty between exam forms, so the number of questions you must answer correctly is not a fixed percentage you can calculate in advance. The practical consequence: do not set a goal of "getting 70% right" and assume you are safe. Aim for a comfortable margin above that on practice exams.

The Four Content Domains
The exam blueprint is organized into four domains. Two of them, Domains 2 and 4, are jointly the largest at 30% each, which together account for well over half of the exam.
| Domain | Name | Weight |
|---|---|---|
| 1 | Anatomy and Physiology | 25% |
| 2 | Lymphedema, Vascular, and Related Disorders | 30% |
| 3 | Patient Evaluation and Treatment Planning | 15% |
| 4 | Management of Lymphedema and Related Disorders | 30% |
Domain 1: Anatomy and Physiology (25%)
This is the foundation. Expect questions on the structure and function of the lymphatic system and its relationship to the venous and arterial circulation.
- Lymphatic vessel anatomy, lymph nodes, and drainage territories
- Fluid dynamics at the capillary level and how lymph forms and moves
- Watersheds and the pathways that connect drainage regions
Domain 2: Lymphedema, Vascular, and Related Disorders (30%)
One of the two heaviest domains. It covers primary and secondary lymphedema, fat disorders, and arteriovenous disease, and it rewards candidates who can distinguish between conditions that look similar at the bedside.
- Primary versus secondary lymphedema: causes and presentation
- Fat disorders and how they differ from lymphedema
- Venous and arterial disease and why they change treatment decisions
Domain 3: Patient Evaluation and Treatment Planning (15%)
The smallest domain, but one that ties the others together. Questions here ask you to turn assessment findings into a sensible plan.
- History taking, observation, and measurement
- Identifying red flags and contraindications
- Setting goals and selecting treatment components
Domain 4: Management of Lymphedema and Related Disorders (30%)
The other heavyweight. This is where the clinical skills taught in your CDT program show up as scenario-based questions.
- Phases of CDT and what happens in each
- Compression strategy: bandaging, garments, and when each applies
- Patient education, self-care, and long-term management

Who Hires CLT-LANA Therapists
Lymphedema therapy sits at the intersection of rehabilitation, oncology, and vascular care, so CLT-LANA holders are found across a range of settings. Because the credential presupposes an underlying professional license, most certified therapists are practicing clinicians who add lymphedema expertise to their existing scope.
- Outpatient rehabilitation clinics that run dedicated lymphedema programs alongside physical and occupational therapy services
- Hospital systems and cancer centers, where post-surgical and post-radiation patients are referred for lymphedema risk reduction and treatment
- Specialty lymphedema and wound care clinics, where chronic swelling, venous disease, and skin complications are managed together
- Home health and skilled nursing providers serving patients who cannot easily travel for care
- Private practice, where certified therapists build referral relationships with surgeons, oncologists, and vascular specialists

Sequencing Your Study Around the Domain Weights
You do not need an elaborate method. You need an order that matches how the exam is built. Because Domains 2 and 4 are worth 30% each, and Domain 1 supplies the physiology that makes both of them make sense, a sensible approach is to build from foundation to application and then reserve final weeks for mixed practice.
Domain 1 foundation
- Lymphatic anatomy, drainage territories, and fluid dynamics
- Anchor each concept to a clinical consequence so it sticks
Domain 2 conditions
- Primary versus secondary lymphedema
- Compare fat disorders and venous or arterial disease against lymphedema
Domain 4 management
- CDT phases, compression choices, and patient education
- Work scenario questions that force a treatment decision
Domain 3 plus mixed review
- Evaluation, contraindications, and goal setting
- Timed sets of mixed questions in four-option format
Adjust the pacing to your own calendar and background. A physical therapist may move quickly through assessment topics but need extra time on vascular pathology, while a nurse may find the reverse. For a fuller plan, see the CLT-LANA Study Guide 2026: How to Pass on Your First Attempt, and when you are ready to test yourself under realistic conditions, try our original questions in the CLT-LANA practice test.
Key Takeaway
Because the exam is closed book and weighted toward Domains 2 and 4, prioritize being able to recognize a condition from a short clinical description and then choose the appropriate management step. Recall of isolated facts matters less than applying them to a scenario.
