Allergy, Individual Marker, Apple

To begin any immunotherapy, it is preeminent to establish the root cause of the allergy. Apple allergy tests help in detecting the allergen via a patient's blood sample. Apple allergies are most common in adults and adolescents and are caused by a protein that is also prevalent in birch. Allergic people can experience a sudden onset of itching, sneezing, and hives in their sensitive body parts.

Patients with an IgE of 0.70 kU/L or more are said to have tested positive for apple allergies.

There are a lot of foods that contain the same protein as birch pollen, such as carrots, apricots, etc. In the case of allergies, it is always preferable to avoid them, as this may lead to emergency complications in the future.
