What This Test Measures
The test detects the presence of Immunoglobulin E (IgE) antibodies specific to Dermatophagoides pteronyssinus. IgE is a type of antibody your immune system produces in response to allergens, such as dust mites, which can trigger allergic reactions like sneezing, itching, or skin rashes.
Why It’s Done
Your healthcare provider may recommend this test if you have symptoms like persistent sneezing, itchy eyes, nasal congestion, or skin reactions that suggest an allergy to dust mites. It can also help confirm a diagnosis of allergic rhinitis or asthma linked to mite exposure.
How the Test Works
A small blood sample is taken from your arm and sent to a lab. The serum (liquid part of blood) is analyzed to measure IgE antibodies against Dermatophagoides pteronyssinus. The result indicates whether your immune system is reacting to this allergen.
Preparation
No special preparation is needed for this test. You may have a slight bruise or soreness at the injection site, but this usually goes away quickly.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps diagnose allergies caused by Dermatophagoides pteronyssinus, a common allergen in indoor environments. Elevated IgE levels suggest an allergic reaction, guiding treatment options such as allergy medications, avoidance strategies, or immunotherapy (allergy shots).
Short name
