Rabbit Epithelia (E82) IgE Biomarker Testing
It measures IgE sensitization to rabbit epithelia to help explain allergy symptoms, with easy ordering and results through Vitals Vault and Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
Rabbit Epithelia (E82) IgE is a blood test that looks for allergen-specific IgE antibodies your immune system may make after becoming sensitized to rabbit skin cells, saliva, and dander-like particles (often grouped on reports as “rabbit epithelia”).
This test does not prove you will react every time you are around a rabbit, but it can help explain symptoms that show up with exposure, such as sneezing, itchy eyes, wheezing, cough, hives, or flares of eczema.
Because symptoms and triggers can overlap with other animal and environmental allergies, your result is most useful when you read it alongside your history and other allergy testing, ideally with clinician guidance.
Do I need a Rabbit Epithelia (E82) IgE test?
You may want a Rabbit Epithelia (E82) IgE test if your symptoms reliably show up around rabbits or in spaces where rabbits live. Common patterns include nasal congestion, sneezing, watery or itchy eyes, cough, chest tightness, wheezing, or skin symptoms after handling a rabbit, cleaning a cage, or being in a home with rabbit bedding and hay.
This test can also be helpful if you are trying to sort out whether your symptoms are driven by rabbit exposure versus other common triggers like cats, dogs, dust mites, molds, or seasonal pollens. If you have asthma, recurrent bronchitis-like symptoms, or nighttime cough, identifying an animal trigger can matter for prevention and treatment planning.
You might also consider testing if you work with rabbits (veterinary settings, research facilities, farms, shelters) or if a family member wants to bring a rabbit into the home and you want a clearer risk picture before committing.
Your result should be interpreted in clinical context. Allergy blood tests support clinician-directed care and exposure planning, but they are not a standalone diagnosis of “rabbit allergy.”
This is typically reported as an allergen-specific IgE immunoassay performed in a CLIA-certified laboratory; results should be interpreted with your symptoms and medical history.

If you want a clear, lab-based read on rabbit sensitization, you can order Rabbit Epithelia (E82) IgE through Vitals Vault and complete your blood draw at a participating lab location.
Once your result is back, PocketMD can help you make sense of what “negative,” “low positive,” or “high positive” means for you, and what follow-up questions to bring to your clinician—especially if you have asthma, frequent sinus symptoms, or skin flares.
If your result suggests rabbit sensitization but your symptoms are still confusing, you can use Vitals Vault to add companion allergy tests (for example, other animal danders) so you are not guessing which exposures matter most.
If you are monitoring changes after reducing exposure or changing your environment, Vitals Vault makes it straightforward to reorder and trend results over time.
- Order online and complete your draw at a lab location
- PocketMD guidance for next steps and questions to ask
- Easy retesting to track trends when your exposure changes
Key benefits of Rabbit Epithelia (E82) IgE testing
- Helps identify whether rabbit exposure is a plausible trigger for your nasal, eye, lung, or skin symptoms.
- Supports practical decisions about pet ownership, home exposure reduction, and workplace precautions.
- Adds objective data when symptoms overlap with other animal allergies or seasonal/environmental triggers.
- Can guide which additional allergen tests are worth adding so you test smarter, not broader.
- Helps your clinician tailor an allergy and asthma plan when animal exposure is part of your routine.
- Provides a baseline you can compare against if you change exposure (rehoming, PPE use, cleaning routines).
- Pairs well with PocketMD interpretation so you understand what the number means in real life.
What is Rabbit Epithelia (E82) IgE?
Rabbit Epithelia (E82) IgE is a blood test that measures allergen-specific immunoglobulin E (IgE) directed at rabbit epithelia. In everyday terms, it checks whether your immune system has been “trained” to recognize rabbit-derived proteins as allergens.
When you are sensitized, exposure to rabbit proteins can trigger an immediate-type allergic response. IgE binds to mast cells and basophils, and when the allergen is encountered again, those cells can release histamine and other mediators that drive symptoms like sneezing, itching, hives, or wheezing.
A key point is that sensitization is not the same as clinical allergy. Some people have detectable rabbit-specific IgE but minimal symptoms, while others have strong symptoms with only modest IgE levels. Your exposure intensity (handling, cleaning cages, ventilation, bedding/hay dust) and your underlying conditions (asthma, eczema) strongly influence how you feel.
Rabbit epithelia testing is one piece of an allergy workup. Depending on your situation, your clinician may also consider total IgE, other animal dander IgE tests, and evaluation for non-allergic causes of similar symptoms (like irritant rhinitis or viral-triggered asthma).
What counts as “rabbit exposure”?
Exposure is not limited to touching a rabbit. Proteins can be carried on fur, skin flakes, saliva, and contaminated surfaces, and they can become airborne during cleaning. Symptoms can also be amplified by co-exposures such as hay, bedding dust, or ammonia from urine in poorly ventilated areas.
How this differs from skin testing
Skin-prick testing looks for an immediate skin reaction to allergen extracts, while this blood test measures circulating IgE. Blood testing can be useful if you cannot stop antihistamines, have certain skin conditions, or prefer a blood draw, but the best choice depends on your clinician’s plan and the allergens being evaluated.
What do my Rabbit Epithelia (E82) IgE results mean?
Low or negative Rabbit Epithelia (E82) IgE
A low or negative result means rabbit-specific IgE was not detected or was below the lab’s positivity threshold. This makes IgE-mediated rabbit allergy less likely, but it does not fully rule it out—especially if your symptoms are strong and clearly tied to exposure. Timing can matter, and some reactions may be non-IgE-mediated or driven by other exposures in the rabbit environment (like hay dust or irritants). If your history is convincing, your clinician may consider repeat testing, skin testing, or testing for other animal and environmental allergens.
In-range Rabbit Epithelia (E82) IgE
For allergen-specific IgE, “in-range” often means within the lab’s negative reference interval. If your result is in this range and you still have symptoms, it is a cue to broaden the differential: other animal danders, dust mites, molds, pollens, irritant exposures, or asthma that is not primarily allergy-driven. Your clinician may also focus on symptom timing, home/work environment, and response to avoidance or medications.
High or positive Rabbit Epithelia (E82) IgE
A high or positive result indicates sensitization to rabbit epithelia and increases the likelihood that rabbit exposure contributes to your symptoms. Higher values often correlate with a greater chance of clinical reactivity, but they do not perfectly predict severity. The most actionable next step is usually exposure-focused: reducing contact, improving ventilation and cleaning practices, and reviewing asthma control if you have wheeze or chest tightness. If you have had significant breathing symptoms, facial swelling, or systemic reactions, discuss a safety plan with your clinician.
Factors that influence Rabbit Epithelia (E82) IgE
Your result can be influenced by how much and how often you are exposed, including occupational exposure and whether you clean cages or handle rabbits directly. Co-existing atopic conditions (eczema, allergic rhinitis, asthma) and higher overall allergic tendency can increase the chance of a positive test. Cross-reactivity can occur across animal allergens, so a positive result may coexist with other dander sensitivities that also drive symptoms. Lab methods and reporting scales vary, so it helps to compare results using the same lab when trending over time.

Frequently Asked Questions
What does the Rabbit Epithelia (E82) IgE test measure?
It measures allergen-specific IgE antibodies to rabbit epithelia, which indicates whether your immune system is sensitized to rabbit-derived proteins. It is used to support evaluation of allergy symptoms that may be triggered by rabbit exposure.
Do I need to fast before a rabbit IgE blood test?
Fasting is usually not required for allergen-specific IgE testing. If you are getting other labs at the same visit, follow the instructions for the full set of tests you ordered.
Can a positive rabbit IgE test diagnose a rabbit allergy?
A positive result shows sensitization, not a guaranteed clinical allergy. Diagnosis depends on whether your symptoms match exposure, how consistent the pattern is, and whether other triggers could explain your symptoms.
What if my rabbit IgE is negative but I still react around rabbits?
A negative result makes IgE-mediated rabbit allergy less likely, but it does not rule out other explanations. You could be reacting to other allergens in the environment (such as hay or dust mites), irritants, or have asthma that flares with particles and odors; your clinician may recommend broader allergy testing or different evaluation.
How long after exposure should I wait to test or retest?
There is no single perfect timing, but IgE sensitization is generally stable over weeks to months rather than changing day-to-day. Retesting is most useful after a meaningful change in exposure or treatment plan, and it is best planned with your clinician so the result answers a specific question.
Can antihistamines affect the Rabbit Epithelia (E82) IgE blood test?
Antihistamines typically do not change allergen-specific IgE blood test results. They can affect skin testing, which is one reason a blood test may be chosen in some situations.
What other tests are commonly ordered with rabbit IgE?
Many people add other animal dander IgE tests (such as cat, dog, or horse) and sometimes total IgE, depending on symptoms. If you have wheezing or chronic cough, your clinician may also evaluate asthma control and consider additional respiratory testing.
