Apple Allergy Blood Test in Florida

What this test measures

An allergy to apple is usually caused by an immune response to proteins in the fruit. In many cases it is related to oral allergy syndrome, where proteins similar to pollen allergens cause itching or tingling in the mouth and throat. Symptoms are often mild, but more significant reactions can occur.

Specific IgE testing looks for antibodies that bind to apple proteins. A positive result shows sensitization, which means the immune system recognizes the protein, but it does not by itself prove that a reaction will happen. The result is considered together with what happens when you eat apples.

Apple proteins can also be present in juices, sauces, and baked goods, so the history should include all forms of the fruit. Some people react to raw apples but tolerate cooked apples because heating changes the proteins. A qualified healthcare provider can help interpret these patterns and discuss next steps.
