A positive result means you reacted to a substance. Your health care provider will see a red, raised area called a wheal.
Often, a positive result means the symptoms you are having are due to exposure to that substance. In general, a stronger response means you are more sensitive to the substance.
People can have a positive response to a substance with allergy skin testing, but not have any problems with that substance in everyday life.
Skin tests are usually accurate. However, if the dose of allergen is large, even people who are not allergic will have a positive reaction.
Your health care provider will consider your symptoms and the results of your skin test to suggest lifestyle changes you can make to avoid substances that may be causing your symptoms.
