Tyrophagus Mite IgE Test
The Tyrophagus Mite Allergy Test measures IgE antibodies against Tyrophagus putrescentiae, a storage mite found in grain, flour, and damp stored goods. It helps assess mite sensitization behind persistent nasal or respiratory symptoms.

Quick answer
The Tyrophagus Mite Allergy Test uses a blood sample to measure immunoglobulin E antibodies against Tyrophagus putrescentiae. This mite is a common storage pest that thrives in grain, flour, cheese, and other damp stored products. It is ordered when allergy symptoms occur around stored materials or alongside a broader mite panel. A healthcare provider interprets the result with the symptom history.
What this test measures
Tyrophagus putrescentiae, sometimes called the mold mite or cheese mite, feeds on stored food and grows well in warm, humid conditions. Its particles can become airborne when stored goods are disturbed. Sensitive people may notice sneezing, nasal congestion, itchy eyes, or asthma-like symptoms around these exposures.
The test measures mite-specific IgE in serum using a quantitative immunoassay. A single blood draw is enough, and the laboratory reports the antibody level and a reactivity class. Because storage mites share allergens with house dust mites and other stored-product mites, results are usually reviewed with related tests.
A positive result indicates sensitization rather than an active allergy or a confirmed source of exposure. Clinicians interpret it with the person's environment, work or home setting, and symptoms. People with ongoing respiratory or nasal symptoms should discuss the finding with a qualified healthcare provider.
- Tyrophagus putrescentiae-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for Tyrophagus putrescentiae
- Cross-reactive storage mite allergens
- House dust mite group 2 allergens when included
- Related stored-product mite allergens
Why people order this test
- Investigate nasal or respiratory symptoms tied to stored materials
- Assess occupational exposure to grain, flour, or feed
- Compare reactivity across storage and dust mites
- Evaluate symptoms that worsen in damp environments
- Support a broader allergy workup with a provider
- Follow up on a positive mite screening result
How to prepare
No fasting is needed for this test. A blood sample is drawn from a vein, usually at the arm. Follow any timing or medication instructions provided by the laboratory.
Understanding your results
Results are usually reported within one to three business days. The report shows the specific IgE level and reactivity class for Tyrophagus putrescentiae. An elevated value indicates sensitization, and a qualified healthcare provider interprets it with symptoms and exposure.

Frequently Asked Questions
What is Tyrophagus putrescentiae?
It is a storage mite that lives in grain, flour, cheese, and other stored foods, especially in warm and humid conditions. Its particles can trigger allergic symptoms in sensitive people.
Is this the same as a dust mite?
No. Tyrophagus is a storage mite rather than a house dust mite, though the two groups share some allergens and can produce similar symptoms.
How is the test performed?
A small blood sample is drawn from a vein and tested for IgE antibodies that react to the mite.
Do I need to fast before the test?
Fasting is not required unless the test is bundled with another panel that calls for it.
What does a positive result mean?
It shows that the immune system has produced antibodies against the mite, which indicates sensitization. Whether symptoms are caused by it depends on exposure and clinical history.
