Dermatophagoides pteronyssinus
Use
The Dermatophagoides pteronyssinus (house dust mite) test measures the concentration of IgE antibodies specific to this allergen in serum. It helps diagnose an allergy to Dermatophagoides pteronyssinus, which is a common trigger of allergic reactions, including asthma, rhinitis, and eczema, especially in humid regions where dust mites thrive. This test aids in confirming the diagnosis of allergic conditions resulting from exposure to Dermatophagoides pteronyssinus.
Special Instructions
The test is performed using the Thermo Fisher ImmunoCAP methodology. Ensure proper specimen type and conditions are met for accurate results. Refer to the stability requirements and storage instructions for maintaining specimen integrity before testing.
Limitations
The test may produce false negatives if the patient has been exposed to oral steroids or other immunosuppressive therapies. Cross-reactivity with other allergens can occur, affecting specificity. High total IgE levels or recent allergen exposure might interfere with the test, leading to misleading results. It is crucial to analyze the results in conjunction with the patient's clinical history and other diagnostic findings.
