Order Allergy TestingAllergy testing evaluates how the immune system responds to specific substances, called allergens, that are commonly found in foods, pollens, animal dander, dust mites, molds, insect venoms, and medications. The tests do not diagnose an allergy on their own; they identify sensitization, which is the presence of allergen-specific antibodies. A clinician interprets those findings alongside symptoms and exposure history to determine whether a true allergy exists.
About Allergy Testing in Tustin
Allergy testing measures the body's immune response to selected allergens.
The most common laboratory approach detects allergen-specific immunoglobulin E (IgE) in a blood sample. IgE is the antibody class associated with immediate hypersensitivity reactions such as hives, nasal congestion, wheezing, and, in severe cases, anaphylaxis. Each allergen is tested individually, and the result is reported as a concentration or a class score that reflects the likelihood and degree of sensitization.
A related but distinct method is skin prick testing, in which a small amount of allergen extract is placed on the skin and the surface is lightly pricked. A raised, red wheal indicates a positive response. Blood testing is often chosen when skin testing is impractical, such as when widespread skin conditions are present or when a person cannot safely stop medications that would interfere with skin reactions.
Results are not binary. A positive result means the immune system has produced IgE against that allergen, but it does not guarantee that exposure will cause symptoms. Conversely, a negative result generally makes an allergy less likely but does not always exclude it. Total IgE may also be measured, though it is less specific than allergen-specific testing. Because of these nuances, results should be reviewed with a qualified clinician rather than acted on in isolation.
