Remember that allergies can develop and change throughout your life. While you may test negative for a particular substance now, you could develop an allergy to it later. You may want to undergo additional testing in the future, if you find you have new reactions to once benign substances.
These skin tests can confirm what you may already suspect—that your sneezing, itchy and watery eyes, or hives are the result of an allergy. Your doctor can then use this information to create a personalized treatment plan that may include allergen avoidance, medications to reduce your symptoms, or immunotherapy (allergy shots) to gradually increase your tolerance to allergens.
