Pig Epithelium IgE Test in Arizona

What this test measures

Swine epithelium refers to the skin and tissue cells shed by pigs. These particles can become airborne in barns, pens, and farm environments, and they may also be present in laboratory or veterinary settings. Sensitive people may develop allergy symptoms after inhaling them, including sneezing, a stuffy nose, cough, and in some cases asthma-like breathing changes.

The test measures allergen-specific IgE in a serum sample. It reports a quantitative level and usually a reactivity class for swine epithelium. A single blood draw is required. Because animal allergens from different species can overlap, results are often reviewed alongside tests for other animal epithelia such as cat, dog, and horse.

Farm workers, veterinarians, laboratory staff, and people who keep pigs may be offered this test when symptoms occur around animals. Sensitization on a blood test shows the immune system recognizes swine allergens, but it does not confirm that every symptom is caused by exposure. Clinicians consider the result with the person's history and environment.
