Can You See a Private GP While Registered with the NHS?
We get asked all of the time, “Is it OK that I have an NHS GP?” It absolutely is! It’s
July 7, 2026
Allergies may cause debilitation in individuals, even to the extent of sneezing, itching, rashes, or even serious reactions.
Well, if you feel that allergies are affecting your life, an allergy blood test will do great to allow you to understand more about what’s bothering you.
Our London-based clinics offer comprehensive allergy blood tests to help identify specific allergens and understand the root cause of your symptoms, with no hidden fees and no phlebotomy fee.
Allergy testing is a simple and effective way to detect allergies by measuring the levels of Immunoglobulin E (IgE) in your bloodstream. IgE is an antibody produced by your immune system in response to certain allergens, which may include pollen, dust mites, pet dander, or certain foods.
By analysing your blood, we can pinpoint which substances are triggering your allergic reactions. Unlike skin prick tests, which expose you to potential allergens on your skin, blood tests are non-invasive and can be performed even if you are taking antihistamines.
The prevalence of allergies in the UK is estimated to be approximately 30% of adults and 40% of children, with over 2 million allergy tests taken each year. If one of the following symptoms sounds familiar, an allergy blood test may work for you too:
Allergy blood tests are also suitable for those who suffer from eczema, asthma, or other individuals who suspect they have a food or environmental allergy.
Blood tests are highly reliable and can accurately find both minor and major allergies.
Blood tests are also convenient, since one does not have to stop taking medications such as antihistamines before the test. They are safe for all ages and are thus suitable for children, grown-ups, and individuals suffering from some types of skin diseases or sensitivity that prohibits them from undergoing skin testing.
This procedure is quick since it requires only a small amount of blood, and the results are usually obtained in a matter of days.
Here are a few common issues that are often linked to allergic reactions:

On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly phlebotomists or trained clinicians.
Inform your healthcare provider about any medications you are taking, as some, especially antihistamines or corticosteroids, may affect your test results. Depending on the test, you might need to stop taking allergy medications for a few days beforehand. Follow your doctor’s instructions on when to discontinue these. Allergy blood tests typically do not require fasting unless otherwise instructed.
A healthcare professional will draw blood from your arm, a quick and minimally painful procedure that typically lasts a few minutes. Wear loose clothing with sleeves that can easily be rolled up for the blood draw. Be prepared to share any current allergy symptoms with the healthcare team to ensure the appropriate allergens are tested.
If you have to stop certain medications, check with your doctor about when it is safe to resume them. Blood test results may take a few days to a week, and your healthcare provider will notify you once they are ready. Based on your results, your doctor may recommend allergy treatments, such as medications, immunotherapy, or avoidance strategies.
