The IgE allergy test for Phthalic anhydride (PA) is employed to identify allergic reactions to this low-molecular-weight industrial compound. Exposure to PA can lead to immunologically-mediated respiratory diseases such as asthma and rhinitis. Healthcare professionals utilize this test to diagnose sensitivity, establish allergic status, and provide guidance for allergen-specific immunotherapy.

Important note: Minimum volume is 1 mL and 0.5 mL for every additional allergen.
