This procedure isn't as sensitive as skin testing. The most effective way to prevent allergic reactions is to avoid exposure to the things that cause them. This is far easier if the allergen is something easily identified and not present in our usual environment. A person who is allergic to strawberries can more easily live an allergy-free life than can someone who is allergic to dust mites. There are measures people who are allergic to unavoidable substances can take to minimize contact with these allergens.
Dust masks can help prevent inhaling airborne allergens such as pollen and mold.
Masks worn while mowing the lawn or raking leaves can make these chores bearable. Delegating these jobs to someone who isn't allergic is an even better avoidance strategy. Molds and dust mites in the home are difficult to eliminate. Removing carpets, venetian blinds, and fluffy bedding such as feather pillows will help clear the air in the home. Getting rid of unused clothing in the closets will help cut down on mold and dust mites.
