What is this test?

This is a qualitative laboratory test that detects IgE antibodies directed against the rMal d 3 allergen component associated with apple. The test has been deprecated, so a newer or more appropriate allergy evaluation may be recommended.

Why might I need this test?

It may have been used to evaluate a suspected food allergy or to investigate whether symptoms such as hives, swelling, wheezing, or digestive discomfort could be related to an apple allergen. The result must be considered together with the foods eaten, symptoms, timing, and other allergy tests.

How is the test performed?

A blood sample is tested for allergen-specific IgE using laboratory antibody analysis. Because this test is deprecated, the laboratory may recommend another testing method or component.

How do I prepare for the test?

No special preparation is usually required for a blood draw. Do not stop allergy medicines or antihistamines unless your healthcare professional specifically advises you to do so.

Reference range

Adult: 10-40 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Frequently asked questions

Does a positive result mean I am allergic to apple?
Not necessarily. It shows sensitization to rMal d 3, and your clinician must interpret it alongside your symptoms and other findings before diagnosing a food allergy.
Why was this test deprecated?
Deprecated tests may have been replaced by newer assays, broader component testing, or testing methods that provide more useful clinical information. Ask your clinician whether an updated allergy evaluation is appropriate.
Should I stop allergy medication before testing?
Do not stop prescribed medication without instructions from your clinician. Some medicines can affect allergy test interpretation, but stopping them may also allow symptoms to return.
