Rabbit Serum Proteins (E206) IgE Biomarker Testing
It measures IgE antibodies to rabbit serum proteins to assess possible rabbit allergy, with easy ordering and Quest-based lab access via Vitals Vault.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
Rabbit Serum Proteins E206 IgE is a blood test that looks for allergen-specific IgE antibodies your immune system may make after exposure to rabbit proteins. A positive result can support the idea that rabbit exposure is contributing to allergy symptoms.
This test is most useful when you have a real-world question to answer, such as whether symptoms flare around a pet rabbit, rabbit bedding/hay, or occupational exposure (for example, veterinary, lab, or animal care settings).
Your number is not a standalone diagnosis. It is one piece of the puzzle alongside your symptom history, timing of exposure, and sometimes other allergy tests.
Do I need a Rabbit Serum Proteins E206 IgE test?
You might consider this test if you get consistent symptoms after being around rabbits or rabbit environments. Common patterns include sneezing, runny or stuffy nose, itchy or watery eyes, cough, wheeze, chest tightness, or flares of eczema that line up with exposure.
It can also be helpful if you are trying to sort out “pet allergies” when you have multiple possible triggers in the home, such as cats, dogs, rodents, hay, or dust mites. When symptoms are intermittent, a specific IgE result can help you and your clinician decide what to prioritize for avoidance steps or environmental controls.
Testing is also reasonable if you have had more concerning reactions (such as hives, swelling, or breathing symptoms) after direct contact, scratches, or saliva exposure. If you have ever had a severe reaction, you should treat this as a medical safety issue and discuss an emergency plan with a clinician.
If you have no symptoms with rabbit exposure, routine screening usually does not add much. Allergy blood tests can be positive without causing noticeable symptoms, so the best use is answering a specific clinical question rather than “testing everything.”
This is a laboratory-developed allergen-specific IgE blood test performed in a CLIA-certified lab; results support clinical evaluation and are not diagnostic on their own.

If you want a clear answer about whether rabbit exposure may be part of your allergy picture, you can order Rabbit Serum Proteins (E206) IgE through Vitals Vault and complete your blood draw at a participating lab location.
Once your results are back, PocketMD can help you translate the number into next steps you can actually use, such as how strongly the result supports rabbit sensitization, what follow-up tests may be worth adding, and when retesting makes sense if your exposure changes.
Vitals Vault is designed for practical decision-making: you can start with a targeted test when you have a specific concern, then expand to related allergens or broader panels only if your results and symptoms point that way.
- Order online and complete your draw at a nationwide lab network
- PocketMD guidance to help you interpret results in context
- Easy re-ordering if you need follow-up testing
Key benefits of Rabbit Serum Proteins E206 IgE testing
- Helps confirm whether your immune system is sensitized to rabbit proteins when symptoms cluster around exposure.
- Supports more targeted avoidance steps (home, workplace, or animal-care settings) instead of guessing.
- Helps distinguish rabbit as a trigger when you have multiple possible pet or environmental allergens.
- Can guide whether broader inhalant allergy testing is worth doing next (rather than ordering large panels upfront).
- Provides a baseline value you can compare over time if exposure changes or symptoms improve with interventions.
- Adds objective data to discussions about allergy medications, environmental controls, or referral for specialist evaluation.
- Pairs well with PocketMD interpretation so your result is tied to a plan, not just a number.
What is Rabbit Serum Proteins E206 IgE?
Rabbit Serum Proteins (E206) IgE is an allergen-specific immunoglobulin E (IgE) test. It measures whether your blood contains IgE antibodies that recognize proteins associated with rabbits. In plain terms, it checks for immune sensitization that can be linked to allergy symptoms.
IgE is the antibody class involved in immediate-type allergic reactions. When you are sensitized, exposure to the allergen can trigger release of histamine and other mediators, leading to symptoms like sneezing, itchy eyes, hives, or asthma-like breathing symptoms.
A key point is that sensitization is not the same as clinical allergy. Some people have detectable specific IgE but do not react in real life, while others have symptoms with low-level results. Your exposure history and symptom timing matter as much as the lab value.
What “E206” means
E206 is the lab’s identifier for rabbit serum proteins as an allergen source in specific IgE testing. Different labs may label rabbit allergens slightly differently, but the goal is the same: to detect IgE that binds rabbit-related proteins.
How this differs from total IgE
Total IgE measures the overall amount of IgE in your blood and can be elevated for many reasons, including eczema, asthma, infections, or multiple allergies. Rabbit E206 IgE is targeted: it asks whether you have IgE directed at rabbit proteins specifically.
What do my Rabbit Serum Proteins E206 IgE results mean?
Low (or negative) Rabbit Serum Proteins E206 IgE
A low or negative result makes rabbit sensitization less likely, especially if you have had regular exposure. However, it does not completely rule out rabbit-related symptoms, because timing, intermittent exposure, and non-IgE mechanisms can still cause irritation or asthma flares. If your symptoms are strong and consistent with exposure, your clinician may consider testing for other common triggers (dust mites, cat/dog, grasses, molds) or evaluating for non-allergic rhinitis or asthma.
In-range Rabbit Serum Proteins E206 IgE
Many labs report specific IgE as a numeric value with interpretation bands (often from negative to higher “classes”). An “in-range” result typically means no meaningful sensitization was detected by that assay. If you still suspect rabbit exposure is a trigger, look at the pattern: do symptoms happen only in certain rooms, with hay/bedding, or during cleaning? That pattern may point to other allergens or irritants rather than rabbit proteins themselves.
High (positive) Rabbit Serum Proteins E206 IgE
A high or positive result means your immune system has made IgE that recognizes rabbit proteins, which supports rabbit sensitization. The higher the value, the more likely it is to be clinically relevant, but the number alone does not predict reaction severity. Use it to connect the dots: if symptoms reliably occur with rabbit exposure and improve when exposure is reduced, the result becomes more actionable. If you have asthma symptoms, a positive result is a reason to take exposure control and symptom management seriously and discuss next steps with a clinician.
Factors that influence Rabbit Serum Proteins E206 IgE
Your result is influenced by how much and how recently you have been exposed to rabbits, including indirect exposure through clothing, cages, bedding, or shared air spaces. Having multiple allergies or higher overall allergic tendency can increase the chance of a positive specific IgE. Some people react more to rabbit-related materials in the environment (like hay, dust, or mites in bedding) than to rabbit proteins themselves, which can make interpretation tricky. Medications like antihistamines do not typically suppress blood IgE results, but recent severe allergic events and changes in exposure can affect levels over time.

Frequently Asked Questions
Do I need to fast for a Rabbit Serum Proteins E206 IgE test?
Fasting is not usually required for allergen-specific IgE blood tests. If you are combining this with other labs that do require fasting, follow the instructions for the full set of tests you ordered.
What does a positive rabbit IgE test mean?
A positive result means you are sensitized: your immune system has IgE antibodies that recognize rabbit proteins. It supports rabbit as a possible trigger, but it does not prove that rabbit exposure is the cause of your symptoms without matching history and timing.
Can I be allergic to rabbits even if the test is negative?
Yes. A negative specific IgE result lowers the likelihood of IgE-mediated rabbit allergy, but symptoms can still come from other allergens in the rabbit environment (such as hay, dust, or mites) or from non-allergic irritation. If symptoms persist, consider broader allergy evaluation and an asthma/rhinitis workup with a clinician.
Does the IgE number predict how severe my reaction will be?
Not reliably. Higher specific IgE levels can increase the likelihood that symptoms are related to that allergen, but severity depends on many factors, including exposure dose, asthma control, and individual sensitivity. Always base safety planning on your real-world reaction history.
How is this different from skin prick testing for rabbit allergy?
This is a blood test that measures rabbit-specific IgE in serum, while skin testing measures an immediate skin response to allergen extracts. Blood testing can be convenient when skin testing is not available or practical, but the best choice depends on your history and your clinician’s approach.
When should I retest rabbit-specific IgE?
Retesting is most useful when something changes, such as new rabbit exposure, major reduction in exposure, or a clear change in symptoms. Many people wait months rather than weeks, because IgE trends typically shift gradually. PocketMD can help you decide whether retesting is likely to change your plan.
