What this test is
This test measures specific IgE antibodies in the blood that react to rat epithelium, which includes tiny skin and tissue particles. Elevated levels suggest sensitization to rat allergens, though a clinician interprets the result alongside your history and symptoms.
What it measures
- Rat epithelium-specific IgE — reflects immune sensitization to rat skin and tissue proteins
- Total IgE (if included) — shows overall allergic antibody level, though it is not specific to rats
- Other allergen-specific IgE (if panel) — helps identify additional sensitivities that may contribute to symptoms
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when someone reports sneezing, wheezing, or skin reactions after contact with rats or in areas where rats are kept. It is also used to help evaluate occupational exposure in research or animal care settings.
Preparation
No special preparation is typically required for this blood test, but follow any instructions provided by the collection site. Check with the lab about medications or timing if you have questions.
How results are reported
Results are reported as a numerical level of specific IgE, often grouped into categories such as negative, low, moderate, or high. Reference ranges and reporting formats vary by laboratory, so your clinician will interpret the findings in context.

FAQ
Frequently asked questions
What does a positive rat allergy test mean?
A positive result means your blood contains IgE antibodies that recognize rat epithelium proteins. It suggests you may be sensitized, but it does not by itself confirm that rats are causing your symptoms. Your clinician will consider your exposure history and symptom pattern.
Can this test tell me if I will have a severe reaction?
No, the level of specific IgE does not reliably predict how severe a reaction will be. Some people with high levels have mild symptoms, while others with lower levels may react more strongly. Always discuss any concerning symptoms with a healthcare professional.
Do I need to avoid my pet rat before the test?
There is no need to change your usual contact with rats before this blood test. The test measures antibodies that persist in your blood, so short-term avoidance is not required. Follow any instructions from your clinician or the collection lab.
How long does it take to get results?
Most results are available within a few business days, though timing can vary by laboratory and location. Your ordering clinician will receive the report and discuss what it means for you.
