Testing & treatment of allergy symptoms

An allergy disorder causes the body to become hypersensitive to ordinarily harmless substances, including medicines, foods, inhalants, insects, and household products.

Drawing on over 26 years of medical expertise, our clinics ensure patients fully understand their diagnoses, explore all treatment options, and have every question answered.

At City Walk-in Clinic, we offer a comprehensive Allergy Panel blood test designed to help you identify the substances your body may be reacting to, with a clear report and guidance on next steps. Our testing process is private, professional, and tailored to your needs.

Comprehensive Allergy Panel: What’s Included

Our Allergy Panel package is one of the most extensive tests available, covering a broad range of common allergens in a single blood test:

  • Animal food allergens
  • Plant food allergens
  • Dairy & lactose intolerance
  • Nuts & seeds sensitivities
  • Seafood sensitivities
  • Environmental allergens (pollen, dust, mould spores)
  • Insect allergens
  • Spore & mould responses

Each result is reviewed by our experienced clinicians, helping you and your care team understand which substances may be contributing to your symptoms.

Who Should Consider Allergy Testing?

Allergy testing may be suitable if you:

  • Have ongoing or unexplained symptoms after eating certain foods
  • Experience seasonal or environmental reactions
  • Need clarity on whether symptoms are allergic or intolerance-related
  • Want to discuss results with a healthcare professional

We can also advise on further testing or management options based on your individual health profile.

Allergies

Allergic reactions are usually rapid and can trigger an inflammatory response that ranges from uncomfortable to dangerous. Food allergies can cause serious reactions, but also diarrhoea, itching, nausea, abdominal pain and headaches.

You might not realise the cause of your symptoms as they are not immediate or are ongoing. Other allergies, such as inhalants, can cause respiratory problems and exacerbate existing conditions such as asthma.

Our allergy testing is performed via blood samples sent to a leading laboratory for comprehensive analysis, with no hidden costs.

Key benefits

Allergy testing accurately identifies specific allergens that cause allergic reactions in an individual. This precise identification is crucial for effective management and treatment of allergies.

Once the allergens are identified, healthcare providers can develop personalised treatment plans. These may include avoidance strategies, medications, or immunotherapy, tailored to the individual’s specific allergic triggers.

By knowing exactly what triggers an allergic reaction, individuals can take proactive steps to avoid those allergens, significantly reducing the risk of severe reactions such as anaphylaxis.

The facts

An estimated 10% to 30% of the global population has an allergic disease. This wide range indicates the commonality of allergies worldwide.

In allergy testing studies, food sensitisation detection rates can reach 95% in tested individuals, with common allergens including peanuts, eggs, and soy.

One UK survey found self-reported food allergy rates as high as 15%, which is significantly higher than rates reported from clinical diagnoses by doctors.

Allergy testing plays a crucial role in the management of anaphylaxis, a severe allergic reaction. Early identification of allergens can be life-saving in such cases.

What are they?

Allergies are the immune system’s hypersensitive responses to substances that are generally harmless to most people. These substances, known as allergens, can include pollen, dust mites, mold, pet dander, certain foods, and insect stings.

When a person with an allergy comes into contact with an allergen, their immune system reacts as though it is a harmful invader, releasing chemicals like histamine. This reaction can cause symptoms ranging from mild, such as sneezing and itching, to severe, such as difficulty breathing and anaphylaxis. Allergies can affect anyone, regardless of age, and can develop at any time in life. They are diagnosed through various tests, including skin prick tests, blood tests, and elimination diets.

The Procedure

preparing for appointment

Pre-Appointment

  • If you are coming in for a blood test, it is best to arrive well-hydrated.
  • Certain medications, particularly antihistamines, can interfere with allergy test results. Your doctor may advise you to stop taking these medications several days before the test.
  • If you’re having a skin test, avoid applying lotions or creams to the test area before the appointment, as these can affect test results.

during the appointment

Appointment

  • The allergy test is a simple blood test.
  • A needle is inserted into a vein, usually on the inner arm near the elbow, and a small amount of blood is drawn.
  • You may feel a pricking or scratching sensation.
  • A blood sample is taken and analyzed for specific antibodies produced in response to allergens.

post appointment

Post-Appointment

  • To get the most appropriate test we encourage our patients to have a consultation with a GP to discuss all their concerns and symptoms.
  • Based on that the doctor will suggest the best combination of tests and give you a call with an explanation of results and follow-up management.
  • If you decide to have just to blood test with us you will need to take the results to your own doctor for interpretation or return for a consultation with us.

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.

Do I have an allergy or a sensitivity?
There is a difference between an allergy and sensitivity or intolerance. Even if you are not positive for an allergy, you may well be sensitive or intolerant to certain foods and an elimination diet will help you and the doctor understand the cause of your symptoms.
Why do some people have more allergies than others?
The exact mechanism of allergy is not fully understood. Genetic and hereditary factors play a big role, as well as living in an urban environment or area with high pollution. Some allergies may come and go, whilst others may be chronic.
What is the cause of an allergic reaction?
An allergic reaction is the immune system’s inflammatory response to an allergen. There are countless allergens in the environment that can trigger these reactions. The most common are dust, pollen, pet dander, chemicals, medications, and foods.
Are food allergies different from other types of allergies?
Food allergies involve the immune system reacting to specific proteins in food and can cause mild to severe reactions, including anaphylaxis, which requires immediate medical attention.
