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.

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.
