Allergen Specific IgE Pigeon Feathers (sIgE) Biomarker Testing
It measures IgE sensitization to pigeon feather proteins to support allergy evaluation, with Vitals Vault ordering and Quest lab collection.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
This test checks whether your immune system has made IgE antibodies against proteins associated with pigeon feathers. A positive result suggests sensitization, which can support an allergy workup when it matches your symptoms and exposure.
It can be useful if you have sneezing, runny nose, itchy eyes, wheezing, cough, or flares of eczema that seem worse around birds, feather bedding, lofts, or indoor environments where feather dust accumulates.
Because IgE tests can be positive even when you feel fine, the most helpful interpretation combines your number with your history, timing (seasonal vs year-round), and what happens when you reduce exposure.
Do I need a Allergen Specific IgE Pigeon Feathers test?
You might consider pigeon feather specific IgE testing if you get allergy-like symptoms after being around pigeons or feather dust, such as nasal congestion, sneezing, post-nasal drip, itchy or watery eyes, chest tightness, wheeze, or a persistent cough. It can also help if your symptoms are hard to explain and you suspect an indoor trigger, especially when symptoms worsen at home, in a loft, or in buildings where birds roost.
This test is also reasonable if you have atopic conditions (asthma, allergic rhinitis, or eczema) and you are trying to identify which exposures are worth targeting first. If you are already avoiding obvious triggers but still have symptoms, a targeted IgE result can help you decide whether to broaden testing to other aeroallergens.
You may not need this test if you have never had symptoms with bird or feather exposure, or if your symptoms clearly track with another known trigger. A positive IgE without symptoms does not automatically mean you have a clinically meaningful allergy.
Testing is meant to support clinician-directed care and shared decision-making, not to diagnose or treat on its own.
This is a laboratory-developed specific IgE blood test performed in a CLIA-certified lab; results indicate sensitization and must be interpreted with your symptoms and exposure history.

Get this test with Vitals Vault
Vitals Vault lets you order pigeon feather specific IgE testing without needing a referral, and you can complete your blood draw at a participating Quest location. Your report shows your measured specific IgE level and the lab’s reference interpretation so you can discuss next steps with confidence.
If your result is positive, PocketMD can help you put it in context—whether it fits allergic rhinitis or asthma patterns, whether exposure reduction is likely to matter, and when it makes sense to expand to broader aeroallergen testing. If your result is negative but symptoms persist, PocketMD can also help you think through non-IgE causes and alternative testing.
You can use this test as a focused check when you have a clear exposure question, or as part of a broader strategy to map triggers and track changes after environmental adjustments.
- Order online and draw at Quest locations
- Clear, shareable results for your clinician or allergist
- PocketMD support to interpret results in context
Key benefits of Allergen Specific IgE Pigeon Feathers testing
- Helps confirm whether pigeon feather exposure is a plausible trigger when symptoms and timing line up.
- Distinguishes sensitization to pigeon-related proteins from “unknown trigger” allergy symptoms.
- Supports targeted exposure-reduction decisions (home, loft, workplace) instead of broad trial-and-error avoidance.
- Adds objective data when skin testing is not available, not tolerated, or affected by antihistamines.
- Helps guide whether you should expand testing to other indoor aeroallergens when this result is negative.
- Provides a baseline you can trend if your exposure changes or symptoms evolve over time.
- Pairs well with PocketMD interpretation so your number is weighed against symptoms, seasonality, and asthma control.
What is Allergen Specific IgE Pigeon Feathers?
Allergen specific IgE (sIgE) testing measures IgE antibodies in your blood that recognize a particular allergen source—in this case, proteins associated with pigeon feathers and feather dust. IgE is the antibody class involved in immediate-type allergic reactions, which can drive symptoms like sneezing, itching, hives, and asthma flares in sensitized people.
A positive pigeon feather sIgE result means your immune system has become sensitized to that allergen source. Sensitization is not the same as a confirmed clinical allergy. Clinical allergy is more likely when your symptoms reliably occur with exposure and improve when exposure is reduced.
This test is different from tests used for non-IgE lung reactions sometimes discussed with bird exposure (for example, certain forms of hypersensitivity pneumonitis). If you have shortness of breath, feverish episodes after exposure, or progressive breathing issues, you should seek medical evaluation rather than relying on IgE alone.
Specific IgE vs total IgE
Specific IgE focuses on one allergen source, while total IgE is a broad measure that can be elevated for many reasons (atopy, eczema, parasites, and more). You can have normal total IgE and still have a meaningful positive specific IgE, or elevated total IgE with negative results to a particular allergen.
Blood test vs skin prick testing
Skin prick testing measures a skin response to allergen extracts, while sIgE measures antibodies in blood. They often correlate, but not perfectly. Blood testing can be convenient if you cannot stop antihistamines, have extensive eczema, or prefer a single blood draw.
What do my Allergen Specific IgE Pigeon Feathers results mean?
Low (negative) pigeon feather specific IgE
A low or negative result makes IgE-mediated pigeon feather allergy less likely, especially if the test was done after you had symptoms and you have ongoing exposure. However, it does not rule out all bird-related problems, and it does not rule out non-IgE triggers like irritants, infections, or other indoor allergens. If your symptoms persist, it may be worth testing other aeroallergens or reviewing your environment and asthma control plan with a clinician.
In-range results (interpretation depends on the lab’s cutoffs)
For specific IgE, “in range” usually means the lab did not detect clinically significant sensitization above its reporting threshold. If you still have symptoms, the next step is often to look for a better match between symptoms and exposures—such as dust mites, molds, animal dander, or pollens—rather than assuming the problem is feathers. Your history matters most: a negative test is more reassuring when your symptoms do not consistently track with pigeon or feather exposure.
High (positive) pigeon feather specific IgE
A high result indicates sensitization to pigeon feather-related proteins, which can support a diagnosis of allergy when your symptoms occur with exposure. Higher numbers often correlate with a greater likelihood of clinical reactivity, but they do not perfectly predict severity. The most practical use of a positive result is to guide an exposure plan (reducing feather dust, improving ventilation and cleaning, and avoiding direct contact) and to decide whether broader allergy testing is needed.
Factors that influence pigeon feather specific IgE
Your result can be influenced by how much and how recently you have been exposed, and whether you have other atopic conditions like eczema or asthma that increase the chance of multiple positive IgE tests. Cross-reactivity can occur when proteins from different birds or environmental sources share similar structures, so a positive result may not always pinpoint a single exact trigger. Medications like antihistamines do not typically suppress blood IgE levels (unlike skin testing), but immune-modifying therapies and major changes in exposure over time can affect results. Lab methods and reporting thresholds vary, so comparing results is most meaningful when you use the same lab over time.

Frequently Asked Questions
What does a pigeon feather IgE blood test measure?
It measures allergen-specific IgE antibodies in your blood that recognize proteins associated with pigeon feathers and feather dust. It is used to assess sensitization, which is most meaningful when it matches symptoms after exposure.
Do I need to fast for a pigeon feather specific IgE test?
Fasting is not typically required for allergen-specific IgE blood testing. If you are getting other labs at the same visit, follow the fasting instructions for those tests.
Can I have a positive IgE test but no allergy symptoms?
Yes. A positive specific IgE means sensitization, not necessarily a clinically important allergy. Symptoms, timing, and improvement with avoidance are what determine whether the sensitization is relevant.
Does a negative pigeon feather IgE rule out bird-related breathing problems?
No. It makes IgE-mediated allergy less likely, but it does not rule out other conditions or non-IgE reactions that can be associated with bird exposure. If you have significant or worsening breathing symptoms, you should seek medical evaluation.
Is this the same as testing for “feather pillow allergy”?
Not exactly. Some people react to dust mites or other contaminants in bedding rather than feathers themselves. If your symptoms are mainly in bed or at night, it can be helpful to test common indoor allergens (like dust mites) in addition to any feather-related testing.
How does this compare with skin prick testing?
Skin testing measures a skin reaction to allergen extracts, while this blood test measures IgE antibodies. They often agree, but either can be positive when the other is negative. Blood testing can be easier if you cannot stop antihistamines or have skin conditions that make skin testing difficult.
