The rat allergy test is a blood test that checks for an allergic response to proteins found in rat urine, saliva, and dander. It is usually ordered when a person has symptoms such as sneezing, wheezing, or hives after being around rats, often in a home or workplace setting.

What it measures

  • Specific IgE to rat epithelium — Antibodies that react to proteins in rat skin and fur.
  • Specific IgE to rat urine proteins — Antibodies that react to proteins in rat urine, a common allergen.
  • Specific IgE to rat saliva proteins — Antibodies that react to proteins in rat saliva.
  • Total IgE — A general measure of allergic tendency, not specific to rats.

Who it is for

A doctor or allergist typically orders this test for people with suspected rat allergy, especially those who keep pet rats, work with rats, or live in areas with rodent exposure.

Preparation

No fasting or special preparation is needed. The blood sample can be taken at any time of day.

Results and what they mean

Results are reported as levels of specific IgE antibodies, often on a scale from negative to high. A clinician interprets these numbers along with your symptoms and history. This is general information only and not medical advice.

Is this test painful?

It uses a standard blood draw from a vein, which feels like a quick pinch.

Can this test tell me if I will have a severe reaction?
