Dermatophagoides pteronyssinus-specific Immunoglobulin E (IgE) by Immunofluorescence
This test measures your body’s immune response to a common indoor allergen, Dermatophagoides pteronyssinus, a type of mite found in household dust. It helps identify if your immune system overreacts to this allergen, which may trigger allergic rhinitis, asthma, or other allergic conditions.

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms like sneezing, itchy eyes, nasal congestion, or wheezing that occur after spending time indoors. They might also order it if you have a history of allergies, asthma, or other allergic conditions that could be linked to dust mites.
What to Expect Before the Test
No special preparation is needed for this test. You may have a small blood sample drawn from your arm, or your healthcare provider may collect a sample of your blood serum/plasma. If testing is done on saliva or another specimen type, follow any specific instructions provided by your provider.
What the Test Measures
The test detects the presence of Immunoglobulin E (IgE) antibodies specific to Dermatophagoides pteronyssinus. IgE is a type of antibody produced by your immune system in response to allergens. Elevated levels of this specific IgE may indicate an allergic reaction to this mite.
How the Results Are Interpreted
Results are typically reported as a numerical value indicating the concentration of specific IgE antibodies. While there are no absolute reference ranges, higher levels often suggest a stronger allergic reaction to the allergen. Your healthcare provider will interpret the results in the context of your symptoms and medical history.
Reference range
Adult: 10-40 U/LN/A
