What it measures
- Specific IgE to phthalic anhydride — The main marker; shows whether the immune system has made allergy-type antibodies to this chemical.
- Total IgE — A general measure of allergic antibody level, sometimes used for context.
- Other related acid anhydrides — May be checked together because exposures and reactions can overlap.
- Inhalant allergen panel — Common airborne allergens may be tested to rule out other causes of symptoms.
Preparation
No fasting or special preparation is needed. Timing is not critical, though tell your clinician about any medicines you take, since some can affect allergy testing.
Results and what they mean
Results are reported as a level or class for each specific IgE marker, often alongside a total IgE value. A clinician interprets these in the context of your symptoms, exposure history, and other tests. This is general information only and is not medical advice; discuss your results with a qualified healthcare professional.
