Our diagnostic approach

We employ a comprehensive range of diagnostic techniques to identify the root cause of your allergic conditions. Each testing method has been carefully selected based on extensive research and clinical evidence, allowing us to create the most effective treatment plan for you or your child.

Skin prick testing

A cornerstone of allergy diagnosis, skin prick testing allows us to safely test for multiple allergies in a single session. By introducing tiny amounts of potential allergens just beneath the skin's surface, we can observe and measure your body's immediate responses.




This quick, minimally invasive procedure:

Provides results within 15-20 minutes
Tests multiple allergens simultaneously
Is conducted by experienced allergy nurse specialists

Blood tests for allergies

Blood testing measures specific antibodies in your system, providing a detailed picture of how your body responds to different allergens. By analyzing these markers, known as IgE antibodies, we can identify your triggers with precision. 



This method is valuable because it:

Screens for multiple allergens in a single test
Provides detailed measurements to guide treatment
Offers a comfortable alternative to skin testing
Works alongside other diagnostic methods for comprehensive results

Lung function testing

For patients with respiratory symptoms, our lung function tests provide crucial insights into breathing capacity and airway health. These non-invasive tests help us understand how allergies might be affecting your respiratory system. 


We offer:

Spirometry: Measures breathing capacity and function
Exhaled Nitric Oxide: Indicates airway inflammation
Peak Flow Assessment: Tracks respiratory performance

Food challenge tests

Food challenges are the gold standard for confirming or ruling out food allergies. These carefully controlled tests involve gradually introducing small amounts of specific foods to definitively diagnose or rule out allergies.

When required we:

Conduct carefully controlled food introductions
Provide continuous medical supervision
Follow clear safety protocols
Monitor and document any reactions
