What Does This Test Measure?
The test detects levels of Immunoglobulin E (IgE), a protein produced by your immune system in response to allergens. High IgE levels to *Dermatophagoides pteronyssinus* suggest an allergic reaction to this mite, which is commonly found in household dust.
Why Might You Need This Test?
Your doctor may recommend this test if you experience symptoms like sneezing, itchy eyes, wheezing, or skin reactions (e.g., eczema) that are triggered by exposure to dust mites, especially in indoor environments.
How Is the Test Performed?
A small blood sample is taken from your arm. The sample is then analyzed in a lab to measure IgE antibodies specific to *Dermatophagoides pteronyssinus*. Results are compared to reference ranges to determine if your immune response is elevated.
What Do the Results Mean?
Elevated IgE levels to *Dermatophagoides pteronyssinus* may indicate an allergic sensitivity. However, results alone do not confirm a diagnosis of allergy without clinical correlation (e.g., symptoms, exposure history).
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.
Positive results can support a diagnosis of mite allergy, guiding decisions for allergy testing (e.g., skin prick tests), treatment (e.g., antihistamines, allergy immunotherapy), or environmental modifications (e.g., reducing mite exposure in your home). Results should be interpreted alongside your symptoms and medical history.
Short name
IgE to Dust Mite (D. pteronyssinus)
