What This Test Measures

IgE antibodies are a type of immune protein your body produces in response to allergens. When your body detects *Dermatophagoides pteronyssinus* (a mite found in household dust), it may produce higher-than-normal IgE levels. This test detects those IgE antibodies to determine if you’re sensitized to the mite.

Why It’s Done

Your doctor may order this test if you suspect mite allergies, especially if you experience symptoms like sneezing, itchy eyes, or asthma triggered by dust. It’s often used alongside skin prick tests or other allergy evaluations.

How It Works

A blood sample is taken and analyzed using an immunoassay method. The test detects IgE antibodies specific to *Dermatophagoides pteronyssinus* by measuring their presence and concentration in your serum.

Sample Collection

A small blood sample is drawn from your arm, typically in a clinic or lab setting. The sample is processed and sent for testing. Results are qualitative (positive/negative) rather than a numeric value.

Reference range

INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A

Specimen: serum

Inform your healthcare provider if you are taking blood thinners. No special preparation required.

Frequently asked questions

What does a positive result mean?
A positive result means your body has detected IgE antibodies to *Dermatophagoides pteronyssinus*, which may indicate sensitization. This doesn’t confirm an active allergy but can help guide further evaluation or treatment options.
Can this test replace a skin test?
No. While this test measures IgE antibodies, skin prick tests directly expose your skin to the allergen to check for immediate reactions. Both tests complement each other in allergy diagnosis.
How soon will I get results?
Results are typically available within 1–3 business days, depending on lab processing times. Follow-up with your healthcare provider to discuss next steps.
