Why This Test Might Be Ordered
Your doctor may recommend this test if you experience symptoms like sneezing, itchy eyes, or a runny nose that occur after being in environments with dust mites, such as homes or offices. It may also be used to diagnose or monitor allergies related to dust mite exposure, especially in people with asthma or chronic sinusitis.
What to Expect Before the Test
No special preparation is needed. A blood sample will be drawn from a vein in your arm. The test is typically done in a lab setting and results are usually available within a few days.
What the Test Measures
The test detects the presence of Immunoglobulin E (IgE) antibodies specific to *Dermatophagoides pteronyssus*, a type of dust mite. IgE is a protein produced by your immune system in response to allergens, signaling your body to produce additional antibodies and trigger allergic reactions.
Possible Results and Interpretation
A positive result indicates your immune system has recognized the allergen and produced IgE antibodies. However, elevated IgE levels alone do not confirm an allergy; they may be present in people without symptoms. Your doctor will consider your symptoms, medical history, and other test results to diagnose an allergy.
