The Rat Serum Protein Allergy Test checks a blood sample for antibodies that may indicate an allergic sensitivity to proteins found in rat serum. It is usually ordered when someone has symptoms after contact with rats or their bedding, or when a clinician is evaluating possible animal-related allergy.
What it measures
- Specific IgE to rat serum proteins — Antibodies that can rise with an allergic response to rat proteins.
- Total IgE — A general measure of allergic antibody levels in the blood.
- Serum protein components — Individual protein fractions that may help show which part of the serum triggers a reaction.
- Cross-reactivity markers — Signals that may show whether other animal proteins could also react.
Who it is for
A doctor or allergy specialist typically orders this test for people with suspected animal allergy, especially those who work with or keep rats. It may also be used when other allergy tests do not explain symptoms.
Preparation
No fasting or special preparation is usually required. Tell your clinician about medicines you take, since some drugs can affect allergy test results.
Results and what they mean
Results are reported as antibody levels or as a positive, negative, or borderline finding, depending on the lab. A clinician interprets the result alongside your symptoms and history. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions
Does a positive result mean I am allergic to rats?
Not always. A positive result shows sensitivity, but only a clinician can decide whether it matches a true allergy.
Is this test painful?
It uses a standard blood draw, so you may feel a brief pinch when the needle goes in.
How long do results take?
Most results are ready in about 1 to 3 business days, though timing can vary by lab.
Can I take allergy medicine before the test?
Ask your clinician. Some medicines may need to be stopped before allergy testing.
