Allergy testings for children

Allergy testings for children are very useful to detect the allergen which cause any allergy and be able to offer the best treatment to beat it.

Allergies are common in children, especially food allergies, mites or pollen. As the Spanish Association of Pediatrics indicates, allergic diseases are caused by an exaggerated reaction of the body to some substances that surround us and are, generally, harmless to humans (allergens).

Symptoms of an allergy vary according to the organ affected, level of sensitivity and the time that the person is in contact with the allergen. In any case, if you think your child has any allergy, avoid contact with the substance you believe is the one causing it and go visit the doctor to make him the correspondent test.

Types of allergy testings for children

Various methods are valid in order to detect which allergen causes the allergy:

  • Skin tests: In this type of tests the substances that cause allergy are used more frequently. Skin tests include: 
    • Prick test: it is the most used because it is simple, fast and safe. In this test doctors place a small sample of the allergen under the surface of the skin, usually in the forearm, they wait about 15-20 minutes and after they observe the reaction that can be swelling, redness, hives...You can also find a variant of this test, known as prick-prick, which consists in introducing a sample of the substance in its natural state. 
    • Intradermoreaction: in this type of test the substance is injected into the skin, more deeply than in the prick test, and the reaction is observed at the puncture area.
    • Patch test: this method is used to diagnose the cause of the reaction after the allergen has touched the skin. Doctors apply patches with the substance that can be the cause of the allergy, usually placed in the child back, and after 48 hours they check the reaction of the skin.

Allergy testings for children with food

  • Blood tests: if doctors can not do the skin tests or there are not successful results, the allergist may request that the child be given a blood test. In this type of test doctors measure the levels of allergic IgE antibodies produced when the blood is mixed with the allergen. If the child has an allergy, IgE levels may increase when mixing.
  • Provocation tests: in this type of test the allergen that can be the cause of the allergy is administered, in a controlled and gradual way. These tests are most often used when the allergy is thought to be caused by a drug or a food. And it can be administered through different tracts: oral, conjunctival, nasal or bronchial.
