ALLERGIES

  

      

  

What is an Allergy?  

An allergy is an over-reaction of the immune system, your body's natural defence system.  True allergy occurs when your body releases IgE antibodies in response to to a food or inhalant it mistakenly believes is harmful.  These antibodies can be measured via a blood test in an IgE allergy test.  

  

Allergic reactions are often triggered by foods such as peanuts, tree nuts, shellfish, dairy and eggs and inhaled allergens such as dust, pollen and pet dander.  

  

Allergy symptoms typically appear within minutes and up to two hours after you have been exposed to the food or inhalant allergen. This is one of the differences between fast-onset allergies and food sensitivities which tend to have a delayed onset.

  

Allergy Testing for Food and Inhaled Allergens    

If you suspect that you have an allergy, IgE allergy testing can quickly identify what is triggering your allergic reaction and causing your symptoms.  

  

What is an IgE allergy test?     

An IgE allergy test is a type of blood test used to diagnose allergic reactions.  A sample of your blood is exposed to a range of suspected allergens that may be triggering your allergic reactions.  The amount of antibodies is measured against these allergens.  The blood test measures the actual quantity of IgE antibodies you have for each specific allergen.  One allergy blood test can check for twenty allergens at a time.  

  

How is an allergy test performed?    

A sample of blood is taken.  

The blood is analysed by subjecting it to tests for a range of suspected allergens  

The results indicate how sensitive your are to each allergen on a scale of 0 - 6.

  

What allergens can you be tested for?    

There are four standard testing panels.

  

Panel 1 - a mixture of inhaled and food allergens

Panel 2 - the most important inhaled allergens

Panel 3 - food allergens, characterised as important key allergens

Panel 4 - a selection of 20 inhaled and food allergens, with special consideration to children

  

For each panel, 20 allergens are tested.

  

Why test IgE?   

  • avoids the discomfort associated with skin testing
  • no risk of serious allergic reaction because your body is not directly exposed to the allergen
  • medications such as anti-histamines will not interfere with or skew the results
  • can be performed on patients with severe skin conditions such as eczema or psoriasis
