Storage Mite D71 IgE (Allergy Blood Test) Biomarker Testing
It measures IgE sensitization to storage mites to support allergy evaluation, with convenient ordering and clear results through Vitals Vault and Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.

A Storage Mite D71 IgE test is a blood test that looks for allergen-specific IgE antibodies to a storage mite (an indoor mite that can be found in stored grains, animal feed, and dusty storage areas). Your result helps show whether your immune system is sensitized to this allergen.
This test is most useful when you have allergy-type symptoms and you are trying to match them to a trigger, especially if symptoms flare in barns, grain storage areas, pantries, or other dusty environments. It can also be helpful when skin testing is not practical or you need a blood-based option.
A positive result does not automatically mean the allergen is the cause of your symptoms. The value comes from combining the lab result with your history, timing of symptoms, and—when needed—other allergy tests and a clinician’s evaluation.
Do I need a Storage Mite D71 IgE test?
You might consider Storage Mite D71 IgE testing if you get recurring sneezing, runny or stuffy nose, itchy/watery eyes, cough, wheeze, or chest tightness that seems linked to dusty storage spaces, grain handling, animal feed, or older buildings. Some people notice symptoms at work (agriculture, food storage, animal facilities) more than at home, which can be a clue.
This test can also be a good fit if you cannot stop antihistamines for skin testing, you have skin conditions that make skin-prick testing difficult, or you prefer a blood test to help narrow down likely triggers.
You may not need this specific allergen test if your symptoms are clearly seasonal (for example, only during a pollen season) or if you already have a confirmed trigger that fully explains your symptoms. In those cases, a broader respiratory allergy approach may be more efficient.
Testing supports clinician-directed care and shared decision-making, but it cannot diagnose an allergy condition by itself. Your symptoms, exposures, and response to avoidance or treatment still matter.
This is typically a CLIA-certified laboratory blood test for allergen-specific IgE; results should be interpreted in clinical context and are not a standalone diagnosis.

Key benefits of Storage Mite D71 IgE testing
- Helps identify whether storage mites are a plausible trigger for year-round nasal or breathing symptoms.
- Supports evaluation of work- or environment-related symptoms when exposure happens in barns, grain storage, or dusty facilities.
- Provides a blood-based alternative when skin testing is not feasible or you cannot pause antihistamines.
- Helps distinguish “sensitization” from other causes of similar symptoms, such as infections or irritant exposure.
- Guides practical avoidance steps (cleaning, storage practices, PPE) when exposure reduction is part of your plan.
- Pairs well with other specific IgE tests to map cross-reactivity and co-sensitizations that affect symptom control.
- Creates a baseline you can revisit with PocketMD and your clinician if symptoms change or you retest after interventions.
What is Storage Mite D71 IgE?
Storage Mite D71 IgE is an allergen-specific IgE blood test. It measures the amount of IgE antibody in your blood that recognizes proteins from a storage mite allergen source (often associated with stored grains, animal feed, and dusty storage environments).
IgE is the antibody class involved in immediate-type allergic reactions. If you are sensitized, your immune system has learned to recognize the allergen and can trigger release of histamine and other mediators when you are exposed. That can contribute to allergic rhinitis (hay fever–type symptoms), conjunctivitis (itchy eyes), asthma symptoms, or skin symptoms in some people.
This test does not measure “how allergic you feel,” and it does not prove that storage mites are the only cause of your symptoms. Instead, it provides one piece of evidence that can be matched to your exposure history and symptom timing.
Sensitization vs. clinical allergy
A positive specific IgE result means sensitization: your immune system has IgE that can bind the allergen. Clinical allergy means you actually develop symptoms with real-world exposure. You can be sensitized without noticeable symptoms, and you can have symptoms from other triggers even if this test is negative.
How this differs from total IgE
Total IgE is a broad measure of all IgE in your blood, which can be elevated for many reasons. Storage Mite D71 IgE is targeted to one allergen source. You can have a normal total IgE and still have a positive specific IgE to a particular allergen.
What do my Storage Mite D71 IgE results mean?
Low (or negative) Storage Mite D71 IgE
A low or negative result means the lab did not detect meaningful IgE sensitization to storage mite at the assay’s threshold. This makes storage mite allergy less likely, but it does not completely rule it out—especially if your exposure history is strong or you were tested long after peak exposure. If symptoms persist, your clinician may consider testing for other indoor allergens (dust mites, molds, animal dander) or evaluating non-allergic causes such as irritant rhinitis or reflux.
In-range / expected result
For allergen-specific IgE, there is not a single “optimal” value the way there is for nutrients or hormones. Many people will have an undetectable or very low value, which is generally expected if you are not sensitized. If your result is low but you still have symptoms, the next step is usually to broaden the search for triggers and focus on exposure patterns and symptom timing.
High (positive) Storage Mite D71 IgE
A high or positive result suggests sensitization to storage mite and increases the likelihood that exposure could contribute to your symptoms. Higher values often correlate with a greater chance of clinical reactivity, but they do not perfectly predict severity, and you can still have mild symptoms with a higher number (or significant symptoms with a modest number). Your clinician may use this result to support an avoidance plan, optimize allergy/asthma management, and decide whether additional allergen testing is needed to capture the full trigger profile.
Factors that influence Storage Mite D71 IgE
Your result can be influenced by your recent and ongoing exposure level, your overall atopic tendency (a personal or family history of allergies, eczema, or asthma), and co-sensitization to other mites. Some people show cross-reactivity, where IgE recognizes similar proteins across different mite species, which can complicate pinpointing the exact source. Medications like antihistamines generally do not suppress blood IgE results the way they can affect skin testing, but immune-modulating therapies and timing relative to exposure can still matter. Always interpret the number alongside symptoms and environment.

Frequently Asked Questions
What does a Storage Mite D71 IgE test check for?
It checks for IgE antibodies in your blood that react to storage mite allergen proteins. A positive result indicates sensitization, which can support an allergy evaluation when your symptoms and exposures fit.
Do I need to fast before a Storage Mite D71 IgE blood test?
Fasting is not usually required for allergen-specific IgE testing. If you are combining this with other labs that do require fasting, follow the instructions for the full set of tests you ordered.
Can antihistamines affect Storage Mite D71 IgE results?
Antihistamines typically do not significantly change blood-based specific IgE results, unlike skin-prick testing where they can interfere. If you are on immune-modulating medications or biologics, ask your clinician whether timing could affect interpretation.
What is considered a “positive” D71 IgE result?
Labs report a numeric value with a reference threshold and sometimes class categories. “Positive” usually means the value is above the lab’s detection cutoff, but the clinical meaning depends on your symptoms, exposure history, and whether other allergen tests are also positive.
If my Storage Mite D71 IgE is positive, does that mean I will have severe reactions?
Not necessarily. The number reflects sensitization and can correlate with likelihood of symptoms, but it does not reliably predict severity for every person. Your real-world exposure, asthma status, and other triggers often matter more for risk than the IgE value alone.
When should I retest Storage Mite D71 IgE?
Retesting is usually considered when you have made meaningful exposure changes (for example, workplace controls, storage/cleaning changes) or when your clinician is monitoring an allergy/asthma plan over time. Because IgE can change slowly, retesting is often spaced by months rather than weeks unless there is a specific clinical reason.
Should I test other allergens if this is negative?
If symptoms continue, it is common to test other indoor allergens such as house dust mites, molds, and animal dander, or to use a broader respiratory allergen IgE approach. PocketMD can help you think through which follow-up tests match your exposures.
