This test is performed to determine the amount of specific IgE antibodies present in the blood against the allergen Dermatophagoides pteronyssinus, which is a common house dust mite.
House dust mites are tiny insects found in household dust, particularly in bedding, carpets, and upholstered furniture. They are a common source of allergens that can trigger allergic reactions in susceptible individuals. When a person with a dust mite allergy is exposed to these allergens, their immune system produces IgE antibodies as a defense mechanism.
Measuring the Dermatophagoides pteronyssinus IgE level helps in diagnosing and monitoring allergic conditions related to house dust mite allergies, such as allergic rhinitis (hay fever), asthma, or atopic dermatitis (eczema). It helps healthcare professionals determine the severity of the allergy, identify triggers, and develop an appropriate treatment plan, which may include allergen avoidance, medication, or immunotherapy
