Perennial Allergic Rhinitis Testing
View All TestsWhat Is Perennial Allergic Rhinitis?
Perennial allergic rhinitis is a form of allergic rhinitis that occurs throughout the year, rather than seasonally. It is typically triggered by indoor allergens such as house dust mites, mould spores, pet dander, and cockroach allergens.
Symptoms include persistent nasal congestion, rhinorrhoea (runny nose), post-nasal drip, sneezing, and itchy nose. Because symptoms are constant rather than seasonal, perennial allergic rhinitis is sometimes mistaken for recurrent colds or chronic sinusitis.
Allergy blood testing can help identify the specific indoor allergens you may be sensitised to, providing clarity that supports discussions with your GP or ENT specialist about management.

Frequently Asked Questions
How do I know if my rhinitis is allergic or non-allergic?
An IgE blood test can help distinguish between the two. A positive result to indoor allergens suggests an allergic component, while negative results may indicate non-allergic rhinitis, which has different causes and management approaches.
Why are my symptoms worse when I wake up?
Dust mite allergens are concentrated in bedding. Overnight exposure while sleeping can lead to nasal congestion and sneezing upon waking — a common pattern in perennial allergic rhinitis.
Do I need a GP referral for allergy testing?
No. You can book directly with our clinic without a GP referral. Simply choose your test and select a convenient appointment time. If you're unsure which test is right for your symptoms, our team can help guide your selection.
Do I need to stop taking antihistamines before a blood test?
No. Unlike skin prick testing, IgE blood tests are not affected by antihistamines or other allergy medications. You can continue taking your regular medications before your appointment.
What should I do with my results?
As a diagnostic-only clinic, we provide results directly to you. We recommend sharing them with your GP or ENT specialist for interpretation and to discuss management strategies.
