Children Allergy - Define Triggers Matters

The main thing about any allergy is to make sure that you identify what triggers the child’s problems or symptoms and then once you figure that out, you can help them cope with the symptoms they have.

There are two types of tests available for doctors to distinguish allergen for your child. One is allergy skin test, the other is blood test. By comparison, blood test is more expensive and less sensitive. Skin test can work as the first choice.

How is Allery Skin Test Done?

During allergy skin tests, your skin is exposed to suspected allergens and is then observed for signs of an allergic reaction. Along with your medical history, allergy tests may be able to confirm whether or not a particular substance you touch, breathe or eat is causing symptoms.

Allergy skin tests are widely used to help diagnose allergic conditions, including:

  • Hay fever (allergic rhinitis)
  • Allergic asthma
  • Dermatitis (eczema)
  • Food allergies
  • Penicillin allergy
  • Bee venom allergy
  • Latex allergy

What’s After The Test?

Information from allergy tests may help your doctor develop a treatment plan, this will include

  • allergen avoidance
  • medications
  • allergy shots (immunotherapy)


Skin tests are generally safe for adults and children of all ages, including infants. The most common side effect of skin test is slightly swollen, red, itchy bumps, these bumps are most noticeable during the test but will disappear in a couple of days.

Rarely, allergy skin tests can produce a severe, immediate allergic reaction, so it’s important to have skin tests performed at an office where appropriate emergency equipment and medications are available.

Who Can’t Take Allergy Skin Test?

People who had below situation can’t take allergy skin test because it could be risky.

  • Have ever had a severe allergic reaction. You may be so sensitive to certain substances that even the tiny amounts used in skin tests could trigger a life-threatening reaction (anaphylaxis).
  • Take medications that could interfere with test results. These include antihistamines, many antidepressants and some heartburn medications. Your doctor may determine that it’s better for you to continue taking these medications than to temporarily discontinue them in preparation for a skin test.
  • Have certain skin conditions. If severe eczema or psoriasis affects large areas of skin on your arms and back — the usual testing sites — there may not be enough clear, uninvolved skin to do an effective test. Other skin conditions, such as dermatographism, can cause unreliable test results.

For these groups, blood test will be the alternative.
