What the 15 Domains Actually Are (and Are Not)
Before you build a study plan around the 15 content areas listed in this guide, you need to understand exactly what they represent. They are the 15 instructional headings in the currently linked Blue Heron Academy Lymphedema Education curriculum. They describe what the training provider teaches. They are not an official examination blueprint published by the National Board Certification Agency (NBCA), and they do not prove exhaustive coverage of everything a national exam might ask.
That distinction matters because many candidates assume a numbered list of domains implies published weights. Here, no weights exist. The 15 sections are unweighted preparation headings, so any claim that "Domain 6 is worth a specific percentage of the exam" is editorial at best and invented at worst. When you see a practice-question distribution across these areas, treat it as a study aid built by an exam-prep site, not an official allocation.
For a broader orientation to the credential before you dive into domains, see What Is Lymphedema Technician Certification? and the companion overview at Lymphedema Technician Certification Certification.
Which Credential This Is: AHS, NBCA, and AMMA
Several lymphedema credentials circulate online, and they are not interchangeable. This guide covers the Lymphedema Technician exam issued through American Health Source (AHS), whose examination affiliate is the National Board Certification Agency (NBCA). The exact exam is listed under the American Medical Massage Association (AMMA). The descriptive label used for the credential is not an official examination code; "AHS" is simply the issuer acronym.
This target is not CLT-LANA, a LANA certification, the NAWCCB LLE, or any other lymphedema credential. Do not import their eligibility rules, hour requirements, exam outlines, or fee schedules into your planning. If a study resource talks about a different certifying body's blueprint, it does not apply here.
AHS links Blue Heron lymphedema eLearning from its exact exam listing and identifies Blue Heron as its model training school offering approved eLearning. Blue Heron's own course FAQ states that Lymphedema Technician graduates may take the NBCA AMMA Lymphedema national certification exam. For eligibility details, read Lymphedema Technician Certification Requirements 2026.
One scope reminder: training toward this credential does not confer a professional license or expand your clinical scope of practice. Whatever you learn must be applied within the scope your license and employer allow.
Foundation Domains: Introduction, Homeostasis, and Preventative Care
The first three domains set up the conceptual vocabulary that every later technique section assumes. The six published course learning objectives frame why: students learn the anatomy and physiology of the lymphatic system, the pathology of lymphatic conditions and disorders, and the history of lymphatic therapies, before moving into treatment procedures.
Domain 1: Introduction
The opening section orients you to the subject and to the history of lymphatic therapies, one of the six stated course objectives.
- Know the historical context of lymphatic therapy as a named learning objective
- Be able to define lymphedema in plain terms and distinguish it from general swelling
- Expect terminology questions that reward precise vocabulary
Domain 2: Homeostasis of the Lymphatic System
This is your anatomy-and-physiology anchor. It connects to the course objective on lymphatic anatomy, physiology, and pathology.
- Understand how the lymphatic system maintains fluid balance
- Be able to explain what changes when that balance fails
- Link normal function to the conditions and disorders covered in the pathology objective
Domain 3: General Guidelines and Recommendations for the Preventative Care and Management of Lymphedema
This domain moves from "what is happening" to "what do we advise." It is where consultation skills, a named learning objective, begin to matter.
- Learn the general guidance given for prevention and ongoing management
- Practice distinguishing client self-care recommendations from hands-on technician techniques
- Remember that these are study topics, not clinical treatment instructions for unsupervised care
If you are weighing how much effort these foundations require, How Hard Is the Lymphedema Technician Certification Exam? discusses difficulty in context.
Movement Domains: The Repetitive Movement Technique Sections
The curriculum contains a quirk that trips up candidates. Sections 4 and 11 both read "Repetitive Movement Technique" in the source. This guide preserves both positions rather than silently merging or renaming them. The likeliest reading is that the second appearance revisits or extends the technique later in the curriculum, but the source headings are identical, so rely on your course materials to see what each position actually covers.
Domain 4: Repetitive Movement Technique
The first appearance of the technique heading, early in the treatment sequence.
- Learn the technique's purpose and where it sits among treatment procedures
- Note the terminology exactly as the curriculum uses it
Domain 5: Description of Repetitive Movement Technique, The Repetitive Movement of a Joint through its Prime Plane of Motion
The descriptive companion to Domain 4, centered on moving a joint through its prime plane of motion.
- Know what "prime plane of motion" means for the joint being moved
- Be able to describe the movement conceptually, in your own words
- Pair this with your biomedicine background on the skeletal and muscular systems
Domain 11: Repetitive Movement Technique
The second appearance of the identical heading, positioned after the wrapping sections. Review it as its own entry and compare it against your provider's course text rather than assuming it duplicates Domain 4.
Core Treatment Domains: Lymphedema Technique and Compressive Stroking
These three domains are the heart of the "techniques and treatment procedures" objective. They are procedural, so your goal is to be able to explain each technique clearly and in the right order, using the curriculum's terminology.
Domain 6: Lymphedema Technique
The named technique that gives the credential its identity within the curriculum.
- Understand its role relative to the other techniques in the sequence
- Be ready to describe it in terms of purpose, general approach, and client consultation
Domain 7: Compressive Stroking with Elevation
A technique that combines stroking with positioning of the limb.
- Know why elevation is paired with the stroking technique
- Distinguish it from the movement-based and wrapping-based approaches
Domain 8: Description of Compressive Stroking with Elevation
The descriptive section for Domain 7, where the procedure is laid out in more detail.
- Study the procedure as a sequence, not as isolated facts
- Be able to explain the rationale behind each element
Because the exam format is unverified, avoid memorizing wording. Instead, rehearse explaining each technique aloud. Our Lymphedema Technician Certification Study Guide offers a broader plan for turning this material into recall.
Wrapping Domains: Single and Double Wrapping
Wrapping is among the most procedural parts of the curriculum, and it is split across two domains: a general section on extremity wrapping and a section naming the specific wrap patterns.
Domain 9: Extremity Wrapping Technique
The general introduction to wrapping an arm or leg as part of lymphedema care.
- Understand why wrapping is used and what it is meant to accomplish
- Learn the general principles before the specific patterns
Domain 10: Single Wrapping, Double Wrapping (Cross Hatched Technique)
The specific wrap patterns, including the cross hatched technique.
- Be able to tell single wrapping from double wrapping
- Know what "cross hatched" refers to in this curriculum
- Treat this as a visual-sequential topic: diagram it, then explain it from memory
| Domain group | Domains | What kind of knowledge it rewards |
|---|---|---|
| Foundations | 1, 2, 3 | Vocabulary, physiology, prevention and management guidance |
| Movement | 4, 5, 11 | Joint motion, prime plane, technique description |
| Hands-on treatment | 6, 7, 8 | Procedural sequence and rationale |
| Wrapping | 9, 10 | Pattern recognition and step order |
| Ancillary | 12, 13, 14, 15 | Supporting techniques and client guidance |
Ancillary Domains: Thoracic, Abdominal/Pelvic, and Breathing
The final four domains correspond to the course objective on ancillary techniques and treatment procedures. They broaden your view beyond the limb itself.
Domain 12: Ancillary Techniques for Treatment of Lymphedema
The umbrella section for supporting methods used alongside the primary techniques.
- Understand what makes a technique "ancillary" rather than primary
- Expect this section to introduce the logic of Domains 13 through 15
Domain 13: Thoracic and Intercostal Technique
Work involving the chest wall and the spaces between the ribs.
- Review thoracic anatomy from the biomedicine program
- Be able to explain why the trunk matters to lymphatic care
Domain 14: Abdominal / Pelvic Massage and Manual Therapy
Manual approaches to the abdominal and pelvic regions.
- Connect this domain to the digestive, urinary/excretory, and reproductive systems in the biomedicine material
- Know the purpose of the technique, and remember scope-of-practice limits apply
Domain 15: Therapeutic Breathing Exercises Used in the Treatment of Lymphedema
Breathing exercises as part of treatment.
- Pair with the respiratory and cardiovascular system background
- Be ready to explain what the exercises are meant to support
The Biomedicine Training Program as Background Reading
Blue Heron's linked Biomedicine Training Program is included with all of its provider online education courses. It is background preparation, not a set of extra exam domains with their own weights. It covers general regional anatomy; the skeletal, muscular, integumentary, nervous, cardiovascular, lymphatic, endocrine, respiratory, digestive, urinary/excretory, and reproductive systems; special populations; general musculoskeletal pathology; therapeutic modalities and physiological effects; and an introduction to pharmacology.
Registration, Fee, and Testing Logistics
What is verified about the NBCA Lymphedema Technician Exam is limited but concrete:
- The NBCA's public registration form lists a $125 fee.
- The form asks for registration and payment 30 days before the established or requested exam date.
- NBCA examinations are proctored through testing centers or libraries.
- The NBCA page says several of its exams can use online video testing, but that does not establish remote availability for this exact exam. Confirm current arrangements with NBCA directly.
A separate, advertised NBCA exam eStudy Guide (listed at $40) is described as containing exam topics and content. It was not purchased or accessed for this guide, so nothing here reconstructs its contents. For total cost planning, see Lymphedema Technician Certification Certification Cost, and for scheduling, Lymphedema Technician Certification Exam Dates.
Sequencing the Domains Across Your Prep
You do not need a generic study system here; you need a domain order that respects how the curriculum builds. Foundations first, then techniques that depend on them, then ancillary work.
Foundations (Domains 1-3)
- Lock in lymphatic anatomy, physiology, and homeostasis
- Learn the preventative care and management guidelines
Movement (Domains 4, 5, 11)
- Study both "Repetitive Movement Technique" positions separately
- Review the skeletal and muscular background
Treatment and wrapping (Domains 6-10)
- Rehearse each technique as an ordered sequence
- Diagram single, double, and cross hatched wrapping
Ancillary and review (Domains 12-15)
- Cover thoracic, abdominal/pelvic, and breathing sections
- Do a full pass across all 15 using original practice questions
The Lymphedema Technician Certification Cheat Sheet condenses the must-know facts for the final review week, and you can drill them on the main practice test site. Remember that practice questions there are original supplemental learning aids, not real exam questions, and they do not guarantee passing or certification.
What Has Not Been Verified
Honest preparation means knowing what nobody has confirmed. The following were not verified for the national exam: the number of questions, the time limit, the item format, the passing score, and the current pass rate. Be skeptical of any site stating them as fact.
Also note that the curriculum PDF is currently linked by the provider but carries no verified revision or effective date, so this guide makes no claim of a newly revised 2026 blueprint. Provider statements that its own method is superior, or that other approaches are harmful, are not independently established medical facts and are not presented as such here. Before relying on any of this, confirm the current details with NBCA and AHS, and use the practice test as a supplement rather than a substitute.

Frequently Asked Questions
No. They are the 15 instructional headings in the Blue Heron Academy Lymphedema Education curriculum. They show what the course covers, not an official NBCA blueprint, and they carry no published weights.
Both positions read "Repetitive Movement Technique" in the source curriculum. This guide preserves both rather than merging them, so check your course materials to see what each position covers.
The public NBCA registration form lists a $125 fee and asks for registration and payment 30 days before the exam date. Verify the current fee and process with NBCA before you register.
Those details were not verified. The question count, duration, item format, passing score, and pass rate for the national exam are unconfirmed, and the 70% figure on AHS continuing education quizzes should not be treated as the exam's passing score.
No. Section 16 is the course Final Examination and is not a national-exam content domain. Course completion, the course final, and the separately registered NBCA board exam are three distinct steps.
