Allergy Profile 1 is a blood test that checks your IgE response to a broad panel of foods and inhalants, including peanut, egg, wheat, cow's milk and shellfish, plus grass and tree pollens, house dust mites, and cat and dog dander. It suits anyone with suspected allergic symptoms, such as hives, sneezing or digestive upset, who wants a wide first screen. The panel costs £752.50, plus a £50 blood-draw fee, with results back within 2 days. Walk in or book online at 117a Harley Street, seven days a week.
This profile is commonly requested when someone has symptoms that could be allergic in nature, such as hives, a blocked or runny nose, itchy eyes, or digestive symptoms after eating foods such as egg, wheat, cow's milk or shellfish, but the specific trigger isn't clear.
It also suits situations where both an indoor and an outdoor cause seem possible, since it covers house dust mites and mould alongside grass and tree pollens and cat and dog dander in a single sample.
Parents and adults alike request it to build a broader picture of possible sensitivities, particularly where symptoms have been recurring or difficult to pin down through diet or environment changes alone.
No special preparation is needed for this profile, and most people do not need to fast beforehand. Continuing your usual diet in the days before the test can help, since IgE antibody levels reflect ongoing exposure, though you should follow any specific instruction from your doctor or allergist.
A positive IgE result against an item such as peanut, house dust mite or grass pollen shows that your immune system has produced antibodies to it. This is called sensitisation, and on its own it does not confirm that this item is causing your symptoms; some people show a positive result without ever reacting to that substance in real life. A negative result makes an IgE-mediated allergy to that item less likely but does not rule out other types of sensitivity or intolerance.
Your laboratory report will show which allergens were tested and the reference range used for each. Because a positive result has to be matched against your actual symptoms and history by a clinician before it is called an allergy, book a follow-up with an allergist or GP to interpret the pattern, particularly if you are considering avoiding a food or introducing one back into your diet.

Not on its own. A positive IgE result shows sensitisation, meaning your immune system recognises a substance such as peanut or house dust mite, but a clinician needs to match this against your actual symptoms before it is treated as a confirmed allergy.
It covers common food allergens such as egg, wheat, cow's milk, peanut and shellfish, alongside inhalant triggers including grass and tree pollens, house dust mites, mould, cat and dog dander and latex, plus a total IgE measurement.
It's best to keep your usual diet before testing where possible, since avoiding a food beforehand can affect the result. Speak to your doctor first if you are already avoiding something for medical reasons.
A consultant immunologist or allergist is best placed to interpret the pattern of results alongside your symptoms and history, available at the allergy clinic at Medical Express Clinic.
