Hay Fever Testing
View All TestsWhat is Hay Fever (Allergic Rhinitis)?
Hay fever, also known as allergic rhinitis, is an allergic response to airborne allergens such as pollen, dust mites, and mould spores. Symptoms typically include sneezing, a runny or blocked nose, itchy eyes, and throat irritation.
Seasonal hay fever is commonly triggered by grass, tree, or weed pollens, while perennial (year-round) allergic rhinitis may be caused by indoor allergens such as house dust mites, pet dander, or mould.
Our IgE blood tests can help identify the specific allergens causing your symptoms. Results are provided directly to you to share with your GP or specialist for interpretation and management guidance.

Frequently Asked Questions
How does a hay fever blood test work?
The blood test measures specific IgE antibodies to various airborne allergens including grass pollens, tree pollens, mould spores, and dust mites. Elevated IgE levels to specific allergens indicate sensitisation.
Do I need to stop taking antihistamines before the test?
No, antihistamines do not affect IgE blood test results. You can continue taking your regular allergy medications before your appointment.
Can the test determine the severity of my hay fever?
IgE levels indicate sensitisation to specific allergens, but do not directly correlate with symptom severity. Your GP or specialist can interpret results alongside your clinical symptoms.
What happens after I receive my results?
As a diagnostic-only clinic, we provide your results directly to you. We recommend taking them to your GP or an allergy specialist for interpretation and discussion of management options.
