What Allergy and Immunology Services Are Available
Specialist allergy clinics offer skin-prick testing, specific IgE blood tests, spirometry, patch testing, and allergen immunotherapy, with NHS referral usually made by a GP.
Allergy and clinical immunology services are provided through NHS and private outpatient clinics staffed by consultant allergists and clinical immunologists on the GMC specialist register. These services offer comprehensive assessment and management for patients of all ages, from young children through to older adults.
Services commonly available through specialist allergy clinics include:
-
Allergy skin testing (skin-prick and intradermal testing) to identify environmental, food, and insect venom triggers, guided by clinical history
-
Spirometry and lung function testing to assess respiratory involvement, particularly in asthma
-
Patch testing for contact dermatitis and delayed hypersensitivity reactions — in the UK, this is usually undertaken by dermatology services in line with British Association of Dermatologists (BAD) guidance
-
Targeted blood tests, including specific IgE testing guided by clinical history; investigations are selected based on the individual presentation rather than broad panel testing
-
Allergen immunotherapy (AIT) programmes — subcutaneous immunotherapy (SCIT) is administered in specialist clinic settings with appropriate resuscitation facilities and post-dose observation; sublingual immunotherapy (SLIT) in the UK uses licensed tablets (available for grass pollen, tree pollen, and house dust mite), with the first dose given under medical supervision
Specialist allergy clinics work closely with GPs, paediatricians, dermatologists, and respiratory physicians to ensure a coordinated approach to care. In the NHS, referral is typically made by a GP; private pathways may differ. The NHS service finder and the British Society for Allergy and Clinical Immunology (BSACI) 'Find a Clinic' tool can help patients and clinicians locate accredited services. The aim of specialist allergy care is to identify triggers accurately, develop personalised management plans, and improve quality of life over the long term. Patients are encouraged to bring a detailed symptom history and any previous test results to their initial consultation.
| Allergic Condition | Common Triggers | Key Diagnostic Tests | First-Line Treatment | When to Seek Specialist Referral |
|---|---|---|---|---|
| Allergic Rhinitis (Hay Fever) | Grass/tree pollen, house dust mite, pet dander | Skin-prick testing, specific IgE blood tests | Intranasal corticosteroids, non-sedating antihistamines (cetirizine, loratadine) | Symptoms poorly controlled with first-line treatments; affecting sleep or quality of life |
| Asthma (Allergic) | Aeroallergens, exercise, respiratory irritants | Spirometry, lung function testing, specific IgE | Inhaled corticosteroids and bronchodilators per NICE NG80/BTS-SIGN | Poorly controlled despite standard inhalers; frequent sleep disruption |
| Food Allergy | Peanuts, tree nuts, shellfish, milk, eggs, wheat | Skin-prick testing, specific IgE; assessment per NICE CG116 in children | Allergen avoidance; adrenaline auto-injector (EpiPen/Jext) if anaphylaxis risk | History of systemic or anaphylactic reaction; diagnosis uncertain |
| Urticaria and Angioedema | Often no identifiable IgE-mediated trigger in chronic cases | Targeted blood tests; extensive allergy panel testing usually unnecessary | Stepwise antihistamine approach per BSACI/NICE guidance | Symptoms lasting more than six weeks; voice change or recurrent angioedema |
| Insect Venom Allergy | Bee or wasp stings | Skin-prick/intradermal testing, specific IgE to venom | Adrenaline auto-injector; venom immunotherapy (SCIT) for eligible patients | Any systemic or anaphylactic reaction to a sting |
| Drug Allergy | Penicillin, NSAIDs, anaesthetic agents | Clinical history, supervised challenge testing per NICE CG183 | Avoidance pending assessment; de-labelling where appropriate | Suspected penicillin or antibiotic allergy; reaction to commonly prescribed medicines |
| Atopic Dermatitis (Eczema) | Environmental allergens; food allergy rarely a primary driver | Targeted specific IgE or skin-prick testing where clinically indicated | Emollients, topical corticosteroids; biologics (e.g., dupilumab) for severe disease | Severe or refractory disease; history of immediate food reactions or faltering growth |
Common Allergic Conditions Diagnosed and Treated
Specialist clinics diagnose and treat allergic rhinitis, asthma, food allergy, atopic eczema, urticaria, insect venom allergy, and drug allergy, distinguishing true IgE-mediated allergy from non-allergic conditions.
Specialist allergy clinics are equipped to diagnose and manage a broad spectrum of allergic and immune-mediated conditions. Common UK aeroallergens include grass and tree pollens, house dust mite, and pet dander, all of which are relevant triggers across the country.
Commonly assessed and treated conditions include:
-
Allergic rhinitis (hay fever): Characterised by sneezing, nasal congestion, itchy eyes, and a runny nose, triggered by seasonal or perennial allergens such as grass pollen, house dust mite, or pet dander. See NICE CKS: Allergic rhinitis and NHS guidance for further information.
-
Asthma: A chronic inflammatory airway condition frequently associated with allergic triggers; specialist assessment helps distinguish allergic from non-allergic asthma and guides management in line with NICE NG80 and BTS/SIGN guidance.
-
Food allergies: Including reactions to peanuts, tree nuts, shellfish, milk, eggs, and wheat — ranging from mild pollen food allergy syndrome (PFAS, also known as oral allergy syndrome, in which severe systemic reactions are uncommon) through to anaphylaxis. Assessment in children follows NICE CG116.
-
Atopic dermatitis (eczema): A chronic inflammatory skin condition. Food allergy is not a common driver of eczema in most patients; targeted assessment for food allergy is appropriate where there is a history of immediate reactions, faltering growth, or severe disease, as indiscriminate testing and avoidance can be harmful.
-
Urticaria (hives) and angioedema: Acute or chronic skin reactions. Most chronic spontaneous urticaria is not IgE-mediated; extensive allergy testing is usually unnecessary, and management follows a stepwise antihistamine approach per BSACI and NICE guidance.
-
Insect venom allergy: Bee or wasp stings can provoke life-threatening reactions; venom immunotherapy is available for eligible patients per BSACI guidelines.
-
Drug allergies: Including reactions to antibiotics such as penicillin, non-steroidal anti-inflammatory drugs (NSAIDs), and anaesthetic agents. Assessment should follow NICE CG183, which includes pathways for supervised testing and de-labelling (for example, confirming that a patient labelled as penicillin-allergic can safely receive penicillin), which can significantly widen treatment options.
Accurate diagnosis is essential, as conditions that mimic allergy — such as non-allergic rhinitis or food intolerance — require different management strategies. A thorough clinical history combined with targeted testing allows specialists to distinguish true IgE-mediated allergy from other immune or non-immune mechanisms.
Treatment Options for Allergies and Immune Conditions
Treatment follows a stepwise approach including antihistamines, intranasal corticosteroids, adrenaline auto-injectors, biologic therapies, and allergen immunotherapy, tailored to condition severity and individual need.
Once a diagnosis has been established, specialist allergy services offer a range of evidence-based treatment options tailored to the individual patient's condition, severity, and lifestyle. Management typically follows a stepwise approach, beginning with allergen avoidance strategies before progressing to pharmacological and immunological interventions.
Pharmacological treatments commonly used include:
-
Antihistamines (e.g., cetirizine, loratadine, fexofenadine): First-line agents for allergic rhinitis and urticaria. Although described as non-sedating, some individuals may still experience drowsiness; patients should check the patient information leaflet or SmPC and exercise caution when driving or operating machinery.
-
Intranasal corticosteroids (e.g., fluticasone, mometasone): Highly effective for persistent allergic rhinitis with minimal systemic absorption.
-
Inhaled corticosteroids and bronchodilators: The cornerstone of asthma management, used in combination according to disease severity in line with NICE NG80 and BTS/SIGN guidance. A personalised asthma action plan should be provided to all patients with asthma.
-
Adrenaline (epinephrine) auto-injectors (e.g., EpiPen, Jext): Prescribed for patients at risk of anaphylaxis. Patients should carry two devices at all times, use the device immediately at the first signs of anaphylaxis, call 999 (or 112) immediately, lie down with legs raised (unless breathing is difficult), and administer a second dose if symptoms do not improve after five minutes. Education on correct technique is a critical component of care. See MHRA/eMC SmPCs for full prescribing information.
-
Biologic (monoclonal antibody) therapies: Several options are available in the UK for severe or refractory disease, initiated by specialists in line with NICE Technology Appraisals. These include omalizumab (anti-IgE, for severe allergic asthma and chronic spontaneous urticaria), mepolizumab, benralizumab, reslizumab, dupilumab, and tezepelumab for severe asthma phenotypes. Patients should discuss eligibility with their specialist.
Allergen immunotherapy (AIT) is a disease-modifying approach that can reduce sensitivity to specific allergens over time. In the UK:
-
SCIT is administered as a course of gradually increasing allergen injections in a specialist clinic with resuscitation facilities and a mandatory post-dose observation period.
-
SLIT tablets (licensed for grass pollen, tree pollen, and house dust mite) offer a home-based option after the first supervised dose; unlicensed SLIT drops are not routinely recommended.
-
Both approaches typically require a commitment of approximately three years but can provide long-lasting benefit beyond the treatment period. AIT is not currently used for food allergy in routine UK practice.
Patient education is integral to all treatment plans, covering trigger avoidance, recognition of early warning signs of a severe reaction, and correct use of prescribed medications including rescue inhalers and adrenaline auto-injectors.
If you experience a suspected side effect from any medicine, you can report it to the MHRA via the Yellow Card Scheme at yellowcard.mhra.gov.uk or through the Yellow Card app.

When to Seek Specialist Allergy Care
Call 999 immediately for anaphylaxis; seek a GP referral for severe reactions, poorly controlled asthma, chronic urticaria, suspected food or drug allergy, or symptoms significantly affecting daily life.
Knowing when to seek specialist allergy care is important for patient safety and effective disease management. Whilst mild, infrequent allergic symptoms can often be managed with over-the-counter antihistamines and basic avoidance measures, there are clear situations in which referral to a specialist allergy service is strongly advisable.
Seek emergency help immediately (call 999 or 112) if you experience signs of anaphylaxis, including throat swelling, difficulty breathing, a sudden drop in blood pressure, or loss of consciousness. Use your adrenaline auto-injector without delay if prescribed. Following any episode of suspected anaphylaxis, NICE guidance recommends referral to a specialist allergy clinic for full assessment and ongoing management.
You should ask your GP about a referral to a specialist allergy service if you experience:
-
A severe or anaphylactic reaction to any trigger, including food, insect stings, medicines, or an unknown cause — specialist follow-up is essential after emergency treatment
-
Angioedema, particularly with voice change, stridor, or recurrent episodes without an identified cause (to exclude hereditary angioedema)
-
Poorly controlled asthma despite using standard inhalers, or asthma that frequently disrupts sleep or daily activities
-
Recurrent or unexplained urticaria lasting more than six weeks (chronic urticaria), which warrants specialist assessment
-
Suspected food allergy, particularly where there is a history of systemic reactions, to confirm the diagnosis and receive guidance on avoidance and emergency management
-
Frequent or severe allergic rhinitis not adequately controlled with first-line treatments and affecting quality of life, work, or sleep
-
Suspected drug allergy, especially to commonly prescribed medicines such as penicillin, where formal assessment can safely confirm or exclude the diagnosis and widen treatment options in line with NICE CG183
-
Suspected venom allergy (bee or wasp sting reactions), where venom immunotherapy may be appropriate
In the NHS, referral to a specialist allergy or clinical immunology service is typically made by a GP. The BSACI 'Find a Clinic' tool and NHS service finder can help identify accredited services. Early specialist involvement can prevent unnecessary allergen avoidance, reduce the risk of serious reactions, and significantly improve overall wellbeing. Patients should not hesitate to discuss a referral with their GP if symptoms are persistent, worsening, or impacting daily life.
For patient support and further information, Anaphylaxis UK provides resources on adrenaline auto-injector technique and emergency action plans.
