Mouse Urine Sensitivity Test
A mouse urine allergy blood test measures IgE antibodies against proteins found in mouse urine. It helps investigate persistent nasal, eye, or breathing symptoms where mice are present.

Quick answer
The mouse urine allergy test uses a blood sample to measure immunoglobulin E antibodies directed at proteins in mouse urine. Mouse urine is a major source of indoor allergens, and exposure can contribute to sneezing, itching, and asthma-like symptoms. The test is often ordered alongside other animal and indoor allergen tests when symptoms point to a rodent source. It shows sensitization, and a healthcare provider interprets the result with the person's history.
What this test measures
Mouse allergens are present in urine, saliva, and dander, but urine is a major contributor. The main allergen, often called Mus m 1, is a small protein that becomes airborne in dust and can be inhaled. People who keep pet mice, work in laboratories, or live in buildings with rodent activity may notice symptoms indoors. Reactions can range from mild nasal congestion to more significant breathing difficulty in sensitive individuals.
The test measures allergen-specific IgE in serum with a laboratory immunoassay. A single blood draw is enough, and the laboratory reports the level of mouse urine-specific IgE along with a reactivity class. Because mouse and other rodent allergens can overlap, results are often reviewed with tests for rat, hamster, and house dust mite to build a fuller picture of indoor triggers.
A positive result shows the immune system has produced IgE antibodies against mouse urine proteins, which indicates sensitization rather than a confirmed diagnosis. Symptoms depend on exposure and individual sensitivity. Clinicians use the finding with a symptom history and other tests to decide whether reducing exposure or further evaluation is appropriate. Discuss any result with a qualified healthcare provider.
- Mouse urine-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for mouse urine
- Mus m 1 (major mouse urinary protein)
- Mouse epithelial and dander allergens
- Cross-reactive rodent allergens
Why people order this test
- Investigate persistent nasal, eye, or breathing symptoms indoors
- Assess suspected rodent exposure at home or in a workplace
- Clarify sensitization when other animal allergen tests are positive
- Support evaluation of occupational exposure in laboratories or animal facilities
- Provide objective information before discussing exposure reduction
How to prepare
No fasting is needed for this blood test. A sample is collected from a vein, usually at the arm. Follow any timing or medication instructions provided by the laboratory.
Understanding your results
Results are generally available within one to three business days. The report shows the specific IgE level and a reactivity class for mouse urine, and an elevated value suggests sensitization. Only a healthcare provider can interpret the finding in the context of symptoms and exposure.

Frequently Asked Questions
What does a mouse urine allergy test measure?
It measures IgE antibodies in the blood that react to proteins found in mouse urine. The result shows whether the immune system has been sensitized to this allergen.
Is mouse urine the main source of mouse allergens?
Urine is a major source, but saliva and dander also carry allergens. The main urinary protein is a common target that laboratories test for.
Do I need to fast before this test?
No fasting is required. If the test is bundled with other panels that call for fasting, the laboratory provides specific instructions.
What does a positive result mean?
A positive result indicates sensitization to mouse urine proteins. It does not by itself confirm that symptoms are caused by mouse exposure, which depends on the setting and the individual.
Can the test tell how much exposure I have had?
No. The result reflects whether antibodies are present, not the amount or duration of exposure. A healthcare provider reviews it with the symptom history.
