About this test
The rat allergy test is a blood test that measures immunoglobulin E (IgE) antibodies against rat epithelium, the tissue and skin cells shed by rats. It helps determine whether exposure to rats is contributing to allergy symptoms such as sneezing, nasal congestion, itchy or watery eyes, coughing, or wheezing. Rat allergens can be carried in dander, saliva, and urine and may become airborne in indoor dust. The test is typically ordered for laboratory workers, pet owners, and others who develop symptoms around rats.
What this test measures
- Rat epithelium-specific IgE Detects IgE antibodies that bind to rat epithelium (tissue and skin cell) allergens in the blood.
Who this test may be right for
- Laboratory and animal-care staff with occupational rat exposure.
- Pet owners and household members with symptoms around pet rats.
- People with asthma or rhinitis that worsens in rooms used by rats.
- Those being assessed for suspected rat-related allergy.
Before your visit
- No fasting is required.
- Inform the clinician about antihistamines or other allergy medications.
- Continue prescribed medications unless a healthcare provider says otherwise.
- Wear a short-sleeved or loose top for the blood draw.
Understanding your results
A positive result suggests the body has produced IgE antibodies to rat epithelium, which may indicate a sensitivity contributing to nasal, eye, or airway symptoms around rats. A negative result makes rat allergy less likely but does not exclude urine, serum, or other rat proteins. Because rat allergens can persist in indoor dust, symptoms may continue until exposure is reduced. Discuss results with a healthcare provider for a complete interpretation.
