Targeted allergy testing in London and effective treatment to help you breathe, function, and live comfortably again.
Allergy symptoms occur when the immune system overreacts to substances that are usually harmless, such as pollen, dust mites, foods, or animal dander. Without knowing the trigger, treatment often becomes trial-and-error.
Many patients struggle for years with symptoms that don’t respond to antihistamines, avoiding outdoor activities during pollen season or wondering if their reactions are getting worse over time.
At Altera Medical, we provide private allergy testing and treatment in London, combining advanced diagnostic testing with carefully selected treatments. Our approach focuses on identifying the cause of your symptoms and offering treatment that is medically appropriate, effective, and safe.
At Altera Medical, allergy care begins with accurate diagnosis. We use comprehensive blood testing to identify specific allergens and then tailor treatment based on symptom severity, exposure patterns, and your medical history.
Consultation and assessment by a private GP
Comprehensive allergy blood testing (ALEX2 test)
Hay fever and seasonal allergy treatment
Kenalog™ steroid injection for selected patients
Clear explanation of results and personalised plan
If allergy symptoms are dictating when you can go outside, disturbing your sleep, or forcing you to avoid activities you enjoy, assessment can help you take back control. Patients often seek assessment when experiencing:
Persistent symptoms despite antihistamines
Disrupted sleep or work performance
Avoidance of outdoor activities during pollen season
Unclear or multiple suspected triggers
Worsening symptoms year after year
Book a consultation for allergy testing or hay fever treatment.
What may have started as mild seasonal symptoms can progress to persistent congestion, eye irritation, fatigue, or sleep disruption. This progression can occur because:
Repeated exposure can make the immune system more reactive
Additional sensitivities often appear with age
Tissues remain sensitive even between exposures
Pollen allergies may trigger food reactions (oral allergy syndrome)
The most advanced allergy blood test
Tests up to 300 allergens from one blood sample. ALEX2 detects low-level sensitivities and cross-reactions for a complete allergy profile.
The ALEX2 test can identify:
For hay fever or seasonal allergy
Seasonal allergic rhinitis (hay fever) can be severe and disabling, particularly when symptoms persist despite tablets and nasal sprays.
Kenalog is a long-acting corticosteroid injection that reduces the immune system’s allergic response. It may be suitable for patients with severe hay fever symptoms that significantly affect quality of life.
Potential benefits include:
If allergies are affecting your comfort, sleep, or quality of life, accurate diagnosis and targeted treatment can make a real difference. Book an appointment at Altera Medical for expert allergy testing and treatment in London.
*We serve patients across Greenwich, Blackhorse Road, Orpington, and surrounding areas of South East and East London.
Effects may last several weeks to months, depending on individual response.
When used selectively and appropriately, it can be safe. Medical assessment is essential.
Steroid injections can affect blood sugar. We assess this carefully beforehand.
Blood tests like ALEX2 are more comprehensive, test for more allergens, don’t require stopping antihistamines, and are suitable for patients with skin conditions.
They work differently. Tablets are often first-line; injections may help when symptoms are severe or persistent.
Modern blood tests such as ALEX2 are highly accurate when interpreted alongside symptoms.
The ALEX2 allergy test is an advanced blood test that screens for reactions to up to 300 allergens using molecular diagnostics. Unlike traditional testing that focuses on common allergens, ALEX2 detects sensitivities to pollen, foods, dust mites, animal dander, moulds, and cross-reactive allergens from a single blood sample. This comprehensive approach helps identify hidden triggers and explains why some patients react to foods they’ve never had problems with before.
No. Unlike skin prick testing, ALEX2 blood allergy testing does not require you to stop taking antihistamines beforehand. This makes it more convenient and suitable for patients who rely on daily allergy medication to manage symptoms. Blood tests measure antibodies rather than skin reactions, so antihistamines don’t interfere with results.
Hay fever injection side effects from Kenalog are generally mild when administered appropriately. Common side effects include temporary soreness or bruising at the injection site, mild mood changes, increased appetite, or temporary sleep disruption. For diabetic patients, blood sugar levels may temporarily increase. Serious side effects are rare when the injection is given under proper medical supervision. We discuss all potential risks during your clinical assessment and monitor for contraindications.
