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.
