Allergy Skin

Healthcare professionals perform skin allergy tests by exposing the skin to suspected allergens through methods like skin prick tests, intradermal tests, or patch tests. Reactions such as redness, swelling, or wheal formation indicate possible allergen sensitivity.

Allergy skin tests cause minimal discomfort, often described as a slight pinch or mild itching at the test site. The sensations are typically brief and subside shortly after the procedure.

Skin allergy testing is generally accurate, with skin prick tests offering high sensitivity and specificity for immediate allergic reactions. However, false positives and negatives can occur, so results should be interpreted alongside a patient’s medical history and clinical presentation.
