Phthalic Anhydride

The Comprehensive Health Exposure Panel tests IgE response to insects, plants, chemicals, food additives, and worm allergens.

This test measures the IgE antibody response to phthalic anhydride, a chemical used in making resins. Exposure to this substance can cause eye, respiratory, and skin irritation, and may lead to occupational asthma. It's a quantitative assay that helps in diagnosing allergic diseases when combined with other clinical information.
