Guinea Pig Allergy Blood Test in California

What this test measures

Guinea pigs, also called cavies, shed proteins found in skin flakes, saliva, and urine that can act as airborne allergens. Sensitive people may notice symptoms when cleaning cages or handling the animal, even without direct contact. The test detects the IgE antibodies formed against these guinea pig proteins.

A routine blood draw provides the serum for analysis. Laboratories report guinea pig epithelium or dander-specific IgE, total IgE, and often a reactivity grade. Some panels include specific allergen components such as lipocalins, along with markers for cross-reactivity with other furry animals.

Testing is usually ordered when symptoms consistently follow contact with guinea pigs or when someone with other animal allergies considers keeping one as a pet. Because allergen levels vary by environment, the result is reviewed with the exposure pattern and physical findings.
