Home monitoring system for house dust mite allergens
Effective and economic relief for allergy and asthma sufferers

Allergies affect as high as 40% of the western populations and allergic asthma, eczema and rhinitis are increasingly common conditions. In many cases, symptoms are caused by an allergy to house dust mite (HDM) allergens. Research has shown that over 85% of asthmatics are allergic to HDM allergens. Exposure of children in early years of life to allergens increases their risk of developing allergies. Establishing an allergy-friendly environment is the first step in avoiding common allergens and controlling allergies. Staying clear of allergens gives anti-allergy drugs a better chance to be effective.

House Dust Mites are invisible to the naked eye, being only 0.3mm long. They are most commonly found around the home in bedding, carpets, soft furnishing and upholstery. They require food (usually skin flakes in house dust), warmth and moisture for growth. They do not mind whether the house is clean or untidy. They eat skin flakes and produce droppings loaded with allergens. It is these allergens that cause and trigger allergies.

Dust mite allergen levels vary from house to house. Moisture and temperature affect where the dust mites can grow and factors such as high humidity can create local areas of high dust mite infestation in soft furnishings, bedding and carpets. The appropriate treatment method will depend upon where high allergen levels are found in the home. Until now there has not been an easy and reliable method to find the problem area and check if the treatment has worked.

Mite-Alert is a cost effective monitoring system specifically designed to detect dust mite allergens in your home or work environment. The monitoring system allows patients to quickly and easily test a variety of sites for house dust mite allergen levels. Once ‘hot spots’ are identified they can effectively remove the allergens to provide a safe and healthy indoor environment.

House dust mites feed on skin debris and in order to digest it fully, they re-ingest the partially digested skin several times. Invariably their droppings become more concentrated with digestive enzymes to which susceptible subjects become sensitive. These proteolytic allergens include Der p1 and Der p3 and around 90% of patients with allergies to house dust allergens show positive reaction to each of these allergens.

Although Der p1 was the first proteolytic allergen to be identified, research has shown that around 80% of proteolytic activity of house dust can be contributed to Der p3 compared to less than 10% for Der p1. Research has also shown that it is the proteolytic property of these allergens that damage epithelial cells in the airways and hence cause inflammation.

Mite-Alert has been designed to specifically detect the proteolytic property of Der p3 in house dust samples and therefore provide an excellent screen, not only for the presence of house dust mite allergens, but also for the pathogenic property of the dust samples.
