Private Allergy Clinic London

✓

Consultant-Led Every Time

Every consultation is conducted personally by a GMC-registered specialist consultant — never a nurse or GP alone. Our Medical Director, Professor Michael Rudenko MD PhD FAAAAI, has decades of research experience in allergy, asthma, immunotherapy, and clinical trials.

◆

Advanced Molecular Diagnostics

We offer ALEX³ component-resolved diagnostics (300 allergens and molecular components in a single blood test), ISAC molecular profiling, and a full range of skin prick, intradermal, patch, and challenge tests — enabling precision diagnosis beyond standard IgE screening.

●

Disease-Modifying Treatments

We are one of very few UK private clinics offering the full range of allergen immunotherapy: subcutaneous immunotherapy (SCIT), sublingual immunotherapy (SLIT), venom immunotherapy (VIT), peanut oral immunotherapy (Palforzia®), and biologic therapies including omalizumab (Xolair).

★

Evidence-Based, Not Pseudoscientific

We use only validated, scientifically proven tests and treatments. We do not offer unproven tests such as hair analysis, kinesiology, Vega testing, or non-specific food intolerance panels that are not supported by EAACI or BSACI evidence-based guidelines.

■

Global Network & Continuity of Care

As part of the Global Allergy Network of Excellence, we welcome patients transferring immunotherapy from the US, Europe, Australia, New Zealand, and beyond. We provide long-term care, annual reviews, specialist second opinions, and transition from paediatric to adult allergy services.

Fast Access & Flexible Appointments

Consultant appointments are typically available within one week, and same-day urgent video consultations can often be arranged. No GP referral is required for self-pay patients. We also offer secure UK telemedicine appointments for remote consultations and selected postal testing pathways.

ISAC Component-Resolved Diagnostics

Multiplex IgE testing on a biochip platform. Particularly useful for patients with complex multi-allergen sensitivities, polysensitised individuals, and cases where cross-reactive carbohydrate determinants (CCDs) may confound standard IgE results.

Learn more →

Skin Prick Testing (SPT)

Fast, safe, and highly sensitive. Results available within 20 minutes. Safe from birth when clinically appropriate. Used for inhalant allergens, foods, drugs, insect venoms, and latex. Performed by trained specialist nurses or directly by the consultant.

Specific IgE (RAST) Blood Tests

Quantitative measurement of allergen-specific IgE for over 600 individual allergens. Particularly useful when skin testing is not possible (e.g. severe eczema, antihistamine use, dermographism). Results inform risk level and immunotherapy candidacy.

Allergen Challenge (Provocation) Tests

Supervised oral food challenges (OFC) and drug provocation tests — the gold standard for confirming or excluding allergy. Conducted in clinic with full resuscitation facilities and medical supervision. Used for diagnosis, threshold assessment, and de-labelling.

Patch Testing & Other Specialist Tests

Patch testing for allergic contact dermatitis; urticaria histamine release testing; basophil activation testing; baseline serum tryptase; gluten and lactose intolerance investigations; intradermal testing for drug and venom allergy.

Allergen Immunotherapy (AIT)

The only treatment that addresses the underlying cause of allergy, not just symptoms. Suitable for hay fever, allergic asthma, cat and dog allergy, house dust mite allergy, and venom allergy. Available as:

• SCIT — subcutaneous injections (conventional, cluster, rush, ultra-rush)
• SLIT — sublingual drops or tablets (home-based, 3–5 years)
• VIT — venom immunotherapy for wasp and bee sting allergy

Peanut Oral Immunotherapy (Palforzia®)

Recommended by EAACI 2025 guidelines for children and adolescents aged 4–17 with confirmed peanut allergy. The only licensed medicinal OIT product in the UK. BSACI 2024 prescribing guidance followed. Full pre-treatment food challenge workup required.

Biologic Therapies

Omalizumab (Xolair) — anti-IgE monoclonal antibody for allergic asthma, chronic urticaria, and as an adjunct to OIT in highly sensitised patients. Suitability assessed individually based on age, diagnosis, IgE level, and risk profile. EAACI 2025 also supports omalizumab for IgE-mediated food allergy.

Emergency Medication & Action Plans

Personalised written emergency action plans, adrenaline auto-injector (EpiPen, Jext) prescription and training, and assessment for EURneffy® (the MHRA-approved needle-free adrenaline nasal spray, available on private prescription from October 2025). School and workplace allergy plans provided.

Register & Book

Register online as a new patient at allergycentrelondon.co.uk, then book your consultation. Same-day urgent video appointments can often be arranged — call 020 3143 3449.

Detailed Clinical History

Your consultant will take a thorough history of your symptoms, previous reactions, co-existing conditions, family history, medications, and lifestyle factors. This takes as long as it needs to — no rushed appointments.

Allergy Tests (if appropriate)

Skin prick testing can be performed at the same visit when clinically appropriate (results within 20 minutes). Blood tests for specific IgE and molecular profiling (ALEX³, ISAC) are arranged and results reviewed at a follow-up appointment.

Diagnosis & Personalised Plan

Your consultant will explain your diagnosis clearly, provide a written summary, and agree a personalised treatment plan covering avoidance, medications, emergency planning, immunotherapy options, and any further investigations required. A detailed clinic letter is sent to you and, with consent, to your GP.

Insurance & Payment

We accept most major private health insurance plans. Self-pay patients are also welcome — no GP referral required. Contact us to confirm insurance acceptance before booking. For insured patients, a GP referral letter is often required by your insurer prior to the appointment.

Do I need a GP referral to be seen privately?

No. Self-pay patients do not need a GP referral. You can register and book directly online. If you are using private health insurance, your insurer may require a GP referral letter before they will cover the cost — please check your policy before booking.

How quickly can I get an appointment?

Consultant appointments are typically available within one week. For urgent queries, we will do our best to arrange a same-day phone or video consultation — please register online first and then call 020 3143 3449 to save time.

What is the difference between allergy testing at a private clinic and at my GP?

GPs can request basic allergy blood tests but rarely offer the full diagnostic range available at a specialist clinic. A private allergy clinic provides consultant-level expertise, a much broader test panel (including skin prick testing, intradermal tests, molecular profiling, and supervised food challenges), and the ability to start treatment — including immunotherapy — directly. NHS allergy services are limited and can have very long waiting times.

I have been told I am allergic to many foods based on an IgG test. What should I do?

IgG food tests (often sold as “food intolerance panels”) are not recommended by EAACI, BSACI, or NICE. Elevated IgG to foods is a normal consequence of eating those foods and does not indicate allergy or intolerance. Unnecessary elimination diets based on IgG results can lead to nutritional deficiencies, anxiety, and impaired quality of life. A proper allergy assessment at our clinic can clarify which, if any, foods are genuinely problematic.

I started immunotherapy abroad and am moving to London — can you continue my treatment?

Yes, in many cases. We welcome patients transferring from the US, Europe, Australia, New Zealand, and other countries. We will need to contact your originating physician and confirm vaccine availability in the UK. Please bring all documentation of your current immunotherapy programme to your first consultation. Call us on 020 3143 3449 to discuss your specific situation before booking.
