This test is useful when a dust mite allergy is suspected and to identify the specific molecule that has previously caused a positive result in the associated allergen extract test.
Der p 1 is a cysteine protease located in the gut and in faecal particles of house dust mites. The prevalence of this molecule exceeds 70% among patients sensitised to Dermatophagoides pteronyssinus. Exposure to Der p 1 occurs through inhalation of mite faeces. Symptoms associated with an allergy to this molecule include, primarily, allergic rhinitis, conjunctivitis and coughing due to an itchy throat. In some cases, the allergy may cause skin symptoms and lead to bronchial asthma. There is a high degree of cross-reactivity with the Dermatophagoides farinae Der f 1 molecule. The assessment of sensitisations to Der p 1 is considered important for selecting patients eligible for allergen-specific immunotherapy (AIT).
