Are there other allergens I could be sensitized to?*
Many patients with cypress tree allergy can experience symptoms when exposed to other allergens such as tree, weed, or grass pollens, making it difficult to determine which pollen is causing the symptoms, especially when pollen seasons are overlapping. This is called cross-reactivity and occurs when your body's immune system identifies the proteins, or components, in different substances as being structurally similar or biologically related, thus triggering a response. Other respiratory allergens that may cause reactions associated with cypress pollen allergy include junipers, cypresses, and limited pines and other weed, tree, and grass pollens.5
Knowing the proteins, or components, within each allergen that are triggering your symptoms can help guide your management plan. With that in mind, and based on your symptom history, your healthcare provider may suggest something called a specific IgE component test, which can help reveal other pollens you may react to. Results from this test can also help your healthcare provider decide if allergen immunotherapy may reduce your symptoms.5
Already have your specific IgE component test results?
Your component test results will include the name of the components (a series of letters and numbers). Your healthcare provider will likely review the results with you, but here you'll find an at-a-glance breakdown you can use as a reference. Simply match the component names to the list below to see what they mean in terms of symptom management.
nCup a 1
- Indicates symptoms are caused by one or more trees of the Cupressaceae family, e.g., cypress, Japanese cypress, mountain juniper, or Japanese cedar.5
- Patient may be considered for cypress pollen immunotherapy.5
rBet v 2, rBet v 4
- Pollen allergy symptoms may be caused by any tree, weed, or grass pollen. 5
- If experiencing Pollen Food Allergy Syndrome (PFAS) to apple, cherry, hazelnut, etc., birch pollen allergy may be the cause.5
Test results should be interpreted by your healthcare provider in the context of your clinical history. Final diagnosis and decision on further management is made by your healthcare provider.
