Only a specialist (allergist) with a focus on allergology can clearly identify whether you have a house dust mite allergy. Firstly, the doctor will discuss your medical history which provides vital information. This helps the Doctor to get important information
on the type of allergy and the possible triggers.
To identify the allergy trigger the Doctor may perform an allergy test. The most common and recommended allergy test is the skin prick test. Skin prick test is also the preferred test(5) as it is reliable,
inexpensive and provides quick results. Rarely an intradermal test may be used. A blood test in the laboratory may also be utilized to detect allergen-specific IgE. However, both the skin tests and blood analysis only
show a sensitivity to the allergen in question, a so-called sensitization. This is not tantamount to a dust mite allergy. It is a dust mite allergy, only when the medical history coincides with the sensitization.(6)
To confirm the skin test results or if there is doubt in the diagnosis, provocation test can be performed. If the patient responds to the allergen with typical allergy symptoms such as runny nose, sneezing, watery eyes, the diagnosis is confirmed and
the causative allergen is identified without a doubt.(6)
