hickory and pecan tree allergy test

This test measures IgG4 antibodies against pecan or hickory tree pollen. IgG4 antibodies develop with prolonged or repeated allergen exposure and may indicate tolerance or desensitization, particularly after allergy immunotherapy. Elevated IgG4 (compared to IgE) can suggest successful allergy treatment. This test is used to assess the effectiveness of allergy immunotherapy and monitor immune tolerance development to tree pollens. It's more specific than IgE for evaluating long-term immune responses.

Pecan and hickory tree IgE antibodies indicate a potential allergic reaction to pollen from these trees. An IgE antibody test detects whether your immune system has become sensitized to these tree allergens. Elevated IgE suggests a true tree pollen allergy, causing seasonal respiratory symptoms like sneezing, congestion, itchy throat, or asthma flares during tree pollen season. This test helps identify the specific allergen source.
