Indoor Allergy Testing
View All TestsWhat Are Indoor Allergies?
Indoor allergies are allergic responses triggered by allergens found inside buildings — homes, offices, schools, and other enclosed environments. Unlike seasonal allergies, indoor allergies can cause symptoms year-round, as the allergen sources are present regardless of the time of year.
The most common indoor allergens include house dust mites, mould spores, pet dander, and cockroach particles. In London, where many people live and work in compact, centrally heated properties with limited natural ventilation, indoor allergen levels can be particularly significant.
Our blood tests can identify specific IgE antibodies to indoor allergens. Results are provided directly to you to share with your GP or specialist for interpretation and guidance on environmental management strategies.

Frequently Asked Questions
Why are my allergy symptoms worse at home?
Indoor allergens such as dust mites, pet dander, and mould are concentrated in enclosed spaces. Bedding, carpets, and upholstered furniture are common reservoirs. Allergy testing can help identify which specific indoor allergens you may be sensitised to.
Can indoor allergies cause year-round symptoms?
Yes. Unlike seasonal pollen allergies, indoor allergens are present throughout the year. This is known as perennial allergic rhinitis and can sometimes be misattributed to recurrent colds.
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 specialist for interpretation and to discuss environmental control measures.
