Allergy Testing

Introduction and Overview

The Allergy Testing Service at Nottingham Road Clinic provides specialist-led assessment, investigation and management of suspected allergic disease. Allergic conditions are common and can affect multiple organ systems, including the skin, respiratory tract, gastrointestinal system and cardiovascular system. Symptoms may be mild and intermittent or severe and potentially life-threatening, and accurate diagnosis is essential to ensure appropriate management and risk reduction.

The service is delivered by clinicians with specialist experience in allergy assessment, working within a structured, evidence-based framework. Nottingham Road Clinic places emphasis on careful clinical evaluation, recognising that allergy testing must be interpreted in the context of a detailed history and examination. Testing alone is not diagnostic and inappropriate or indiscriminate testing can lead to false labelling of allergy, unnecessary dietary restriction or missed alternative diagnoses.

NRC’s approach to allergy testing is holistic and clinically rigorous. The service focuses on distinguishing true IgE-mediated allergy from non-IgE allergy, intolerance and non-allergic conditions that mimic allergic symptoms. Care pathways are aligned with UK clinical standards and national guidance, with access to diagnostics, pathology and onward referral where required. Management plans are individualised and may involve multidisciplinary input where allergic disease overlaps with respiratory, dermatological, gastrointestinal or psychological conditions.

Who the Service Is For

The Allergy Testing Service is suitable for adults who present with suspected allergic symptoms that require specialist assessment beyond primary care.

This includes patients with:

  • Recurrent or unexplained allergic-type reactions
  • Symptoms temporally linked to foods, medications or environmental exposures
  • Persistent rhinitis, conjunctivitis, urticaria or eczema with suspected allergic triggers
  • Gastrointestinal symptoms where allergy is suspected
  • Previous reactions of unclear mechanism or severity
  • Concern regarding risk of future severe allergic reaction

Specialist input is particularly important where symptoms are recurrent, multisystem, severe, impact daily life, or where incorrect labelling of allergy could affect dietary intake, medication use or occupational safety. The service is appropriate for both self-pay and insured patients and provides referrers with structured assessment, clear interpretation of results and guidance on ongoing management and referral.

Conditions Assessed and Managed

The Allergy Testing Service assesses a broad range of allergic and allergy-related conditions, with careful differentiation from non-allergic disease.

Food allergy and food-related reactions 
Patients may experience gastrointestinal, cutaneous, respiratory or systemic symptoms following ingestion of specific foods. Assessment focuses on identifying true food allergy, differentiating it from food intolerance, functional gastrointestinal disorders and other causes of food-related symptoms.

Environmental and inhalant allergy 
Allergy to pollens, house dust mite, animal dander or moulds may present with rhinitis, conjunctivitis, cough or asthma-like symptoms. Identification of relevant allergens supports targeted management.

Drug allergy and adverse reactions 
Suspected reactions to medications require careful evaluation due to implications for future treatment. Many reported drug allergies are non-immune mediated and benefit from specialist clarification.

Urticaria and angioedema 
Acute or chronic hives and swelling may be allergic, autoimmune or idiopathic. Assessment aims to identify triggers, exclude systemic disease and guide safe management.

Eczema and contact allergy 
Persistent or treatment-resistant skin disease may have allergic or irritant contributors and requires specialist assessment.

Anaphylaxis and severe allergic reactions 
Patients with suspected systemic reactions require structured investigation, risk assessment and clear management planning.

Red-flag allergic presentations 
Rapid onset reactions, airway involvement, cardiovascular compromise or unexplained collapse warrant urgent specialist assessment and escalation pathways.

Clinical Assessment and Diagnostic Approach

Clinical assessment begins with a detailed allergy-focused history, which is central to diagnosis. This includes timing of symptoms, symptom reproducibility, exposure context, severity, treatment response and impact on quality of life. Dietary habits, occupational exposure, medication history and family history of atopy are carefully reviewed.

Physical examination may include:
  • Skin examination for urticaria, eczema or contact dermatitis
  • Respiratory assessment where allergic rhinitis or asthma is suspected
  • General examination to exclude systemic or inflammatory disease

Diagnostic pathways are guided by clinical suspicion and may include:

  • Targeted blood tests for allergen-specific IgE
  • Skin prick testing where appropriate
  • Baseline blood tests to assess inflammatory or immunological contributors
  • Referral for specialist investigations where indicated

All testing is performed and interpreted in line with national guidance, avoiding non-specific panels and ensuring results are clinically meaningful.

Treatments, Procedures and Management Pathways

Management is individualised and based on accurate diagnosis, risk stratification and symptom burden.

Treatment pathways may include:
  • Targeted allergen avoidance strategies based on clinical relevance
  • Pharmacological management such as antihistamines or inhaled therapies
  • Review of medication safety and future prescribing implications
  • Education on recognition and management of allergic reactions
  • Ongoing monitoring for evolving or uncertain presentations
Conservative and non-pharmacological approaches are rioritized where appropriate. Follow-up ensures management remains proportionate, evidence-based and aligned with changes in symptoms or risk profile.

Multidisciplinary Working and Onward Referral

Allergic disease frequently overlaps with other specialties. The service works closely with:

  • Respiratory services for allergic asthma and rhinitis
  • Dermatology for complex or treatment-resistant skin disease
  • Gastroenterology for suspected food-related gastrointestinal symptoms
  • Dietetic services where dietary modification is required
  • Mental health support where anxiety related to allergies impacts wellbeing
  • Primary care for shared management
  • NHS allergy or tertiary services for complex or high-risk cases

This coordinated approach supports safe, comprehensive care and appropriate escalation when required.

What Patients Can Expect from an Appointment

Appointments are clinician-led and structured to provide clarity and reassurance.

Patients can expect:
  • Detailed discussion of symptoms, exposures and concerns
  • Review of previous investigations and treatments
  • Targeted physical examination where indicated
  • Clear explanation of whether symptoms are likely allergic in origin
  • Discussion of recommended tests and their limitations
  • Development of a personalised management plan with agreed follow-up

Clear written communication is provided to patients and referrers to support continuity of care.

Frequently Asked Questions

Does a positive allergy test mean a true allergy is present?
No. Test results must be interpreted alongside symptoms and clinical history.

Can food intolerance be mistaken for allergy?
Yes. Many food-related symptoms are not immune-mediated and require different management.

Are broad allergy panels recommended?
No. Targeted testing is recommended to avoid false-positive results and unnecessary restriction.

Can allergies develop in adulthood?
Yes. Adult-onset allergic disease is recognised and may present in varied ways.

What happens if no allergy is identified?
Alternative causes of symptoms are explored and appropriate referral or management is arranged.

Can results support NHS care?
Yes. Findings can inform NHS referral and shared care pathways where appropriate.
