Mainly, have in notice that allergy tests are not the only base for allergy diagnosis or treatment. Doctor makes an allergy diagnosis based on numerous aspects:

Allergy tests assist your doctor approve allergies your child may have. When an allergy test determines a specific allergen(s) reaction, your doctor also can use this data in developing “immunotherapy” — allergy shots — exactly for your child, if right.
The most common allergy tests are the skin prick tests. Small quantities of suspect allergy triggers are lead through the arm or back skin by pricking or piercing the skin with a needle or like device. If your child is substance allergic, you will see an elevated, red itchy bump, also called a “wheal.” Responses typically act within 15 minutes.

Skin tests and these blood tests are very similar in their capability to analyze sensitivity to specific allergens. Both tests kinds are deliberated to be about 90 percent precise.
