The rat urine allergy test checks for an allergic response to proteins found in rat urine. It is usually ordered when someone has ongoing allergy symptoms and may be exposed to rats at home, work, or school.

What it measures

  • Rat urine protein-specific IgE — An antibody tied to allergic reactions against rat urine proteins.
  • Total IgE — A general allergy-related antibody level that can help show an allergic tendency.
  • Rat serum albumin-specific IgE — An antibody against a protein also found in rat urine.
  • Rat urine protein-specific IgG — An antibody that may show exposure without proving allergy.

Who it is for

A clinician may order this test for people with sneezing, runny nose, itchy eyes, or asthma symptoms around rats or their droppings. It is often used for pet owners, lab workers, or pest-control workers.

Preparation

No fasting or special timing is needed. Tell your clinician about any allergy medicines you take, because some can affect test results.

Results and what they mean

Results are reported as levels of specific antibodies, often with a reference range. A clinician interprets them alongside your symptoms and exposure history; a positive result alone does not prove allergy. This is general information, not medical advice.

Frequently asked questions

Does this test hurt?

It uses a urine sample, so there is no needle or pain.

Can I take allergy medicine before the test?

Ask your clinician. Some medicines may change results, but do not stop any medicine without checking first.

How long do results take?

Most results are ready in 1 to 3 business days.

What if my result is positive?

A positive result means you may be sensitized to rat urine proteins. Your clinician will decide what it means for you.
