Are there other allergens I could be sensitized to?*
Many patients with dust mite allergy can experience symptoms when exposed to other allergens such as different species of dust mites, cockroaches, shellfish, and helminths (e.g., Ascaris lumbricoides). 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.4
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 your specific risk profile concerning dust mite. Results from this test can also help your healthcare provider decide if allergen immunotherapy may reduce your symptoms.4
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.4
rDer p 1, rDer p 2, rDer p 23
- Indicates that the symptoms may be caused by dust mites.
- Strongly associated with asthma.
- Dust mite immunotherapy may be an option, if positive to Der p 1 and/or 2.
rDer p 10
- Due to cross-reactivity, symptoms may be caused by cockroaches, shellfish, and helminths (e.g., Ascaris lumbricoides) as well as different types of dust mites.
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.
