At our London clinic, we offer comprehensive allergy testing, including skin prick tests and IgE blood tests. During the initial consultation with our allergy specialist, Dr Elena Salagean, you can undergo skin prick testing for up to 10 allergens.
The allergy testing process involves several key steps to ensure accuracy and effective diagnosis. We begin with a detailed medical history, discussing your symptoms, their duration, any family history of allergies, and potential triggers. This essential information helps us select the most appropriate testing approach for you.
Skin Prick Tests
Skin prick testing is often the first method used to investigate potential allergies due to its reliability and efficiency. During the procedure, small amounts of different allergens are introduced to the skin, usually on the forearm or back.
A gentle prick or scratch is then made on the skin. Within 15-20 minutes, an allergic reaction may present as a raised, red bump at the test site, similar to a mosquito bite. This quick method is highly effective in pinpointing the allergens affecting you.
IgE Blood Testing
IgE blood tests are another option for allergy diagnosis. This involves taking a small blood sample. These tests measure the level of specific IgE antibodies produced in response to allergens and can indicate what types of allergy you might be having.
Blood testing can be particularly useful for individuals who are unable to undergo skin prick testing due to skin conditions like eczema or medication that may interfere with skin testing.
Common Allergies in London
Hayfever
In London, hay fever (seasonal allergic rhinitis) is one of the most common allergies we see. Symptoms tend to worsen between late March and September when pollen counts are highest.
Symptoms of hay fever include nasal congestion or a runny nose, itchy or watery eyes, an itchy throat, sneezing, and coughing.
The most prevalent cause of hay fever in London is pollen. Grass pollen is most common from May to July, while tree pollen is prevalent from February to June. Weed pollen can also be a trigger from June to September.
Managing hay fever typically involves avoiding pollen exposure and using antihistamines, nasal corticosteroids, and anti-allergy eye drops to alleviate symptoms. While these treatments effectively manage symptoms, they do not cure the underlying condition.

Dust & Mould
During the winter allergy period, London can encounter an increase in dust and mould allergy. These indoor allergens become particularly troublesome when windows remain closed and heating systems circulate indoor air, trapping allergens inside.
Dust mites, for example, thrive in these warm and humid environments. They are frequently found in bedding, upholstery, and carpets.
Mould spores flourish in damp and poorly ventilated spaces and these also become more prevalent during the colder months. In London, where many older homes are characterised by period architecture and variable insulation standards, mould growth can affect a large number of buildings.
Traditional Victorian or Edwardian properties, as well as some post-war builds, often lack the modern ventilation systems and insulation that help keep humidity within the healthy levels of between 30% and 50%. Bathrooms, kitchens, basements, and areas around windows are typical hotspots for mould growth. Older structures with persistent damp issues can harbour mould in hidden corners, behind wallpaper, or around poorly sealed window frames.
If allergic to these, it could cause you to have difficulty breathing or a blocked or runny nose when you are indoors.
Food Allergy
Food allergy is very common throughout the UK. With just over 8 million people living in London, this makes food allergies a very common presentation. They can range from mild to more severe reactions, including anaphylaxis.
If you suspect that you may have a food allergy and you live in London or surrounding areas, the first step is to get a reliable allergy test. For this, you can contact your GP or contact us if you want to have the food allergy test done privately.
