Everything About Allergy

A patient may undergo certain tests to determine the specific allergens to which the patient is allergic to. A skin test or blood test may be done, depending on the condition of the patient.

Skin testing is also called puncture or prick testing. Allergen samples are introduced to the patient’s skin. Only a small amount is placed to avoid a full blown allergic reaction. Usual area for skin test is inside the forearm. Within 30 minutes, an inflammatory reaction will occur if the patient is allergic to the substance. Allergists interpret the reaction.

If a patient has had a history of a life threatening allergic reaction, a blood test is preferred.
