ALEX² Molecular Allergy Blood Testing in Leicester
A Comprehensive Allergy Blood Test for Children and Adults
ALEX² (Allergy Explorer) is one of the most advanced molecular allergy tests available at The Health Suite Leicester, analysing up to 300 allergens and allergen components from a single blood sample. It provides detailed insights into sensitisation patterns and cross-reactive proteins, helping build a clearer picture of complex or multi-allergen symptoms.
What the ALEX² Test Includes
- A single blood sample taken onsite
- Analysis of up to 300 allergen extracts and components
- Total IgE and specific IgE reporting
- Assessment of cross-reactivity markers (including CCD)
- A detailed laboratory report sent to your clinician
No follow-up consultation is included with the test. Interpretation requires a clinician and can be booked separately if needed.
When is ALEX² Useful?
ALEX² is recommended when:
- Multiple allergies are suspected
- Skin prick testing results need further clarification
- The child has eczema, asthma or hay fever that is difficult to control
- Reactions occur without a clear trigger
- There is suspected pollen–food syndrome
- Nuts, seeds or legumes cause uncertain reactions
- Previous tests showed broad sensitisation patterns
It is suitable for children and adults.
ALEX² and Skin Prick Testing: How They Work Together
ALEX² does not replace skin prick testing. Skin prick testing is typically the first-line assessment because:
- It provides immediate results
- It is highly reliable for many common allergens
- It is performed during the consultation itself
ALEX² adds molecular detail, which is helpful when:
- Allergen profiles are complex
- Many potential foods are involved
- Cross-reactivity needs exploring
- The child cannot undergo skin prick testing
Both tests complement each other and are often used in combination for the most accurate picture.
What the ALEX² Test Does NOT Diagnose
ALEX² identifies IgE-mediated allergy sensitisation. It does not diagnose:
- Food intolerances
- Lactose intolerance
- Coeliac disease
- Non-IgE-mediated allergies (e.g., delayed gut reactions)
A clinician will advise if additional testing is needed.
Refer to our ‘Preparing for Your Blood Test’ information before your appointment at The Health Suite.
This page describes the ALEX² test only. A clinical consultation is not included. If you are booking ALEX² for a child without a previous assessment at The Health Suite, a paediatric allergy consultation is required before testing can be arranged.

How ALEX² Works
A clinician-led allergy blood test pathway with specialist consultation, lab analysis, detailed results and optional follow-up support.
Pre-Assessment Requirement
Before booking ALEX² directly for a child, an initial paediatric allergy consultation at The Health Suite is required. This ensures:
- Testing is clinically appropriate
- The correct panel is selected
- Alternative or complementary tests (such as skin prick testing) are not more suitable
Blood Sample Collection
A simple blood test is performed by our clinical team.
Laboratory Analysis
Your sample is processed using ALEX² microarray technology, examining allergen extracts and molecular components.
Comprehensive Report
Your clinician receives:
- Total IgE
- Specific IgE
- Extract-level data
- Component-level data
- Cross-reactive patterns
- Interpretation notes from the laboratory
This report is designed for clinician interpretation.
Optional Follow-Up Consultation
If you would like support in understanding the results or developing a management plan, a follow-up consultation can be arranged separately.
What we treat
At The Health Suite Leicester, our private medical clinic offers expert care whenever you need it. Our team of experienced GPs and healthcare professionals provide personalised diagnosis and treatment for a wide range of medical conditions, ensuring high-quality, professional care in a comfortable setting.
Click below to view useful info on a few of the common conditions we treat:
Comprehensive allergy profiling
We provide detailed IgE analysis against around 300 allergens, including pollen, dust mites, foods, pets, moulds, and insect venoms, to support accurate diagnosis and personalised allergy management planning.
Food allergy sensitisation
We identify specific food allergy triggers and molecular components to help clarify reactions and support safe dietary choices, reducing the risk of allergic responses through precise testing and clinical interpretation.
Environmental allergies
We test for inhalant allergens such as pollens, moulds, and animal dander, helping to identify environmental triggers and guide tailored management strategies to reduce symptoms and improve quality of life.
Cross‑reactivity analysis
Advanced molecular testing helps distinguish true allergic reactions from cross-reactive responses, improving diagnostic accuracy and supporting more targeted and effective allergy management decisions.
Complex or multi‑sensitised cases
This testing is ideal for individuals with multiple symptoms or unclear previous results, providing a deeper understanding of allergic sensitisation patterns to guide specialist-led treatment planning.

Our clinicians manage a broad spectrum of conditions, and individual assessment allows us to tailor care beyond the examples listed. We encourage you to book a consultation to discuss your symptoms and appropriate treatment options.
Symptom checker
If you are experiencing any of these symptoms, please book an appointment with us. Symptoms can vary from person to person and from condition to condition. A proper diagnosis can only be made through a thorough medical examination.
Our clinicians will carry out a full assessment to ensure an accurate diagnosis and appropriate care.
Do you have persistent allergy symptoms like sneezing, itchy eyes, or runny nose?
These may be signs of environmental allergies. ALEX² testing helps identify specific triggers across a wide panel of allergens using a single blood sample.
Are skin rashes, hives, or eczema flares linked to certain exposures?
Complex or chronic skin reactions can be driven by multiple allergens. ALEX² provides detailed insight into specific IgE sensitivities to guide personalised management.
Do you experience digestive symptoms like nausea, vomiting, or diarrhoea after eating?
Food‑related allergic reactions can be difficult to pinpoint. This advanced molecular blood test screens many food allergens and cross‑reactive proteins at once.
Does breathing worsen with seasonal or pet exposure?
Symptoms such as wheezing, coughing or shortness of breath can be linked to allergic sensitisation. ALEX² maps key respiratory allergens in one test.
Have you had unclear or mixed allergy test results in the past?
Standard tests may miss cross‑reactive or molecular allergy patterns. ALEX² expands sensitivity detection and improves allergen identification.
Are symptoms affecting daily life, school, or activity levels?
Ongoing allergic symptoms can impact quality of life. Detailed molecular allergy profiling helps personalise avoidance strategies and treatments.
