Dermatophagoides farinae (d2) IgE details
What Dermatophagoides farinae (d2) IgE shows
Dermatophagoides farinae, often called the American house dust mite, is a microscopic creature that lives in mattresses, pillows, carpets and upholstered furniture, feeding on shed skin flakes and thriving in humid homes. Exposure happens indoors all year round. This test measures IgE antibodies to its proteins to check for sensitization. A positive result can help explain persistent nasal congestion, sneezing, asthma or eczema flares, often worse in the bedroom or in the morning. It closely cross-reacts with D. pteronyssinus, and both are usually tested together. IgE shows sensitization, not necessarily allergy, so the result needs to be read against your symptoms and history.
