Allergic Rhinitis Diagnosis: How Allergy Blood Tests Identify Your Triggers
Understanding how blood tests can help identify the causes of your allergy symptoms
Could a simple blood test help identify what is triggering your allergy symptoms?
When allergic rhinitis is suspected, allergy testing can provide useful information about which substances your immune system reacts to. Blood tests can identify sensitisation to specific allergens, such as pollen, house dust mites, pets and mould, helping healthcare professionals better understand your symptoms and develop a more personalised approach to allergy management.
In this video, Dr. Marinda McDonald from South Africa explains how allergy blood tests work and how the results can contribute to the assessment and management of allergic rhinitis.

Watch the video below to learn how allergy blood tests work and how they can help identify potential triggers of allergic rhinitis.
How can a blood test help with allergies?
Allergic rhinitis can be triggered by a range of substances, including pollen, house dust mites, animal allergens and mould. Identifying which allergens you are sensitised to can provide valuable information when assessing your symptoms.
A blood test can measure allergen-specific IgE antibodies associated with particular allergens. The results can help your healthcare professional determine whether you have sensitisation to specific substances. However, test results are not interpreted in isolation. Your healthcare professional will consider your results alongside your symptoms, medical history and other clinical information.
What happens during an allergy blood test?
An allergy blood test involves taking a small sample of blood, usually from a vein in your arm. The sample is then analysed to look for antibodies associated with specific allergens. Your healthcare professional can explain which allergens are being tested and what your results mean in the context of your symptoms.
What can you do with the results?
Understanding which allergens may be contributing to your symptoms can help you and your healthcare professional develop a more personalised management plan. Depending on your individual situation, this may include strategies to reduce exposure to relevant allergens, medication, or consideration of allergen immunotherapy.
Knowing your triggers can be an important step towards better understanding and managing allergic rhinitis.
