Dermatophagoides pteronyssinus, D1

Dermatophagoides pteronyssinus, also known as the house dust mite, is a common environmental allergen. The D1 laboratory test detects specific IgE antibodies in the blood, indicating sensitivity to this allergen and the risk of allergic reactions.

Role

• Identify individuals allergic to dust mites.
• Prevent allergic reactions and respiratory complications (asthma, rhinitis, conjunctivitis).
• Monitor the immune response to allergen exposure.

Advantages

• Safe and rapid method for allergy screening.
• Enables personalized preventive measures and treatment.
• Can be performed before starting antihistamines or specific immunotherapy.

Indications

• Suspected respiratory allergy (sneezing, nasal itching, runny nose, cough).
• Family history of dust mite allergy.
• Pre-assessment for specific immunotherapy.

Contraindications

• No absolute contraindications; results must be interpreted by a specialist.

Procedure

1. Venous blood sample is collected.
2. The sample is analyzed for D1-specific IgE antibodies.
3. Results are interpreted by a physician.

Results:

• Positive result: Presence of D1-specific IgE antibodies, indicating allergy to dust mites. Avoidance and protective measures are recommended.
• Negative result: No specific antibodies detected, suggesting low risk of allergy to this allergen.
