Skin Allergy Testing London & Skin Prick Test London
Accurate and Immediate Results from Trusted Allergy Experts
At the London Allergy and Immunology Centre, we offer state-of-the-art skin prick testing (SPT) for the diagnosis of a wide range of allergic conditions, including hay fever, food allergy, allergic rhinitis, conjunctivitis, mould allergy, dust mite allergy. This quick, reliable, and minimally invasive test helps identify the specific allergens responsible for your symptoms — providing results within just 15 minutes (appointment can take approximately one hour).
(Please note that antihistamine tablets should be avoided for two days prior to the test)
Why Choose Skin Prick Testing in London?
Skin prick testing remains a gold-standard diagnostic tool for immediate (Type I) IgE-mediated allergic reactions. It is widely used by allergists and immunologists and has been endorsed by recent guidelines from EAACI (2022–2024) and BSACI (2023).
Benefits of Skin Prick Testing:
- Immediate results (within 15–20 minutes)
- Safe and virtually painless, even for babies and young children
- Conducted with validated allergen extracts
- Highly sensitive for airborne allergens and fresh foods
- Enables rapid treatment planning and allergen avoidance strategies
How Skin Prick Testing Works
Our skin prick test involves placing a small droplet of allergen extract (e.g. grass pollen, pet dander, dust mites, or food) on the skin, followed by a gentle superficial touch using a sterile lancet. Positive and negative controls are always used for accuracy.
For suspected food allergies, we may also conduct a modified skin prick test prick-to-prick test using fresh or cooked foods. You are welcome to bring small samples (in individual bags) of any foods you suspect may be causing a reaction.
Is Skin Prick Testing Safe?
Yes — it is extremely safe and well-tolerated. Recent studies confirm its use even in infants from birth. The test causes only mild localised swelling and redness if positive. No systemic allergic reaction is expected under professional supervision.
Our paediatric allergy consultants ensure a child-friendly and relaxed experience. Many children are pleasantly surprised by how gentle and non-invasive the test is.
Same-Day Results in Just 15 Minutes
There’s no need to wait days. Our consultants provide on-the-day interpretation of your results, integrated with your clinical history for a precise diagnosis and personalised treatment plan.

Individual allergy tests can also be done remotely up to three from one sample.
Blood Test vs Skin Prick Test – What’s the Difference?
- Skin Prick Test evaluates the skin’s direct reaction to allergens and reflects actual histamine release. It is affected by taking antihistamines as well as non-specific skin reactivity – dermatographism.
- IgE Blood Test measures circulating allergen-specific antibodies and is not affected by antihistamines or skin conditions.
Many patients benefit from a combination of both tests to achieve an accurate diagnosis, especially when guided by an experienced allergy specialist.

Frequently Asked Questions
How long does skin prick testing take?
The procedure takes about 15 minutes, with results interpreted during your visit that can last about one hour.
Can I take antihistamines before the test?
Antihistamines should be stopped at least 48 hours before testing, as they may affect skin reactivity.
Is the test safe for babies?
Yes. Skin prick tests are safe for infants from birth and are commonly used in paediatric allergy diagnostics.
Is it painful?
No. A tiny lancet gently scratches the skin surface. Most patients describe it as ticklish or mildly irritating.
