What is this test?

This test measures IgE antibodies against proteins found in swine urine. These proteins may act as occupational allergens for people who work with pigs or in related industries.

Why might I need this test?

It may be ordered when a person has respiratory or skin symptoms after workplace exposure to swine. Results can help identify whether swine urine proteins are a possible trigger.

How is the test performed?

A blood sample is tested in a laboratory for antibodies specific to swine urine proteins. The result is reported as positive or negative or with a laboratory-defined measurement, depending on the test method.

How do I prepare for the test?

No special preparation is usually needed. Tell your clinician about recent exposure to swine, your symptoms, other allergies, and any medications or immune treatments that may affect the results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result indicates that the immune system has produced IgE antibodies to swine urine proteins, suggesting sensitization. This may support an occupational allergy when symptoms also occur with relevant exposure, but the result alone does not establish the cause of those symptoms.

Short name

Swine urine protein-specific IgE

Frequently asked questions

Does a positive result mean I am allergic to pigs?
Not necessarily. It shows sensitization to swine urine proteins, and your healthcare professional must interpret it alongside your symptoms and exposure history.
Can skin symptoms be caused by swine urine proteins?
They may be in some exposed individuals. A clinician can assess whether the test result is consistent with your skin or respiratory symptoms.
Can I stop allergy medication before this test?
Do not stop prescribed medication unless your clinician advises you to. Some allergy treatments can affect test results, so discuss any use of antihistamines or biologic therapies beforehand.
