Extremely allergic patients

Oct 9th 2013 at 12:11 AM

If the patient's history and disposal of food suggest specific food allergies, some tests may be useful to evaluate the allergic response food accurately.

Skin tests are quick, simple and relatively safe, but false positives are relatively common. The diagnosis of food allergy is executed only when the patient has a positive skin test to a specific allergen associated with the history of reactions to the same food.
In some extremely allergic patients with severe anaphylactic reactions, skin testing cannot be used due to the risk of potentially fatal reaction.
Skin tests also cannot be performed on patients with extensive eczema. In these cases, opts for evaluation of specific Age in the blood.
These tests are more expensive and, if positive, not necessarily define the diagnosis.
Double-blind tests are the most accurate method to diagnose a food allergy: various foods, including some of which is suspected to cause allergic reactions, are individually packaged in opaque capsules.

The patient swallows a capsule at a time, observing the occurrence of allergic reactions. People with a history of anaphylaxis cannot undergo this examination.
Still, the double-blind is expensive and not effective in detecting multiple food allergies
. For these reasons, it is rarely done, being used when there is a suspicion that intolerance is not due to a specific food. In these cases, the double-blind provides evidence that direct the physician to the true cause of the reaction.
