Identify your allergies with a professional blood test at home. Specific IgE testing for food, environmental and other allergens — no need to stop antihistamines.
Find a Phlebotomist →Allergy blood tests measure specific IgE antibodies your immune system produces in response to allergens.
| Panel | Allergens Tested | Common Triggers |
|---|---|---|
| Food Allergens | Milk, eggs, wheat, peanuts, tree nuts, fish, shellfish, soya | Hives, swelling, digestive symptoms |
| Environmental | Grass pollen, tree pollen, dust mites, mould, pet dander | Hay fever, asthma, rhinitis |
| Total IgE | Overall IgE antibody level | General allergic tendency indicator |
If you experience hives, swelling, digestive issues or anaphylaxis after eating certain foods, IgE testing can identify the specific triggers.
Persistent sneezing, runny nose, itchy eyes or asthma symptoms may be caused by environmental allergens identifiable through blood testing.
Blood testing is particularly useful when skin prick tests cannot be performed due to eczema, dermatitis or other skin conditions.
A single blood draw can test for many allergens at once, which is often easier for children than multiple skin prick tests.
Enter your postcode, choose a time, and select the allergy panel relevant to your symptoms. No GP referral required.
A DBS-checked phlebotomist arrives at your home and collects a venous blood sample. No need to stop antihistamines.
Samples are dispatched to an accredited laboratory the same day. Results typically within three to seven working days.
No fasting is required for allergy blood tests.
Continue taking antihistamines and all other medications as normal.
Make a note of your symptoms and suspected triggers to discuss with your phlebotomist or doctor.
Stay well hydrated to make the blood draw easier.
Wear loose sleeves for easy access to your arm.
An allergy blood test measures specific IgE antibodies in your blood. When your immune system overreacts to a substance (allergen), it produces IgE antibodies specific to that allergen. The blood test detects and measures these antibodies for individual allergens, helping identify what you are allergic to.
Both tests are clinically valid. A blood test has some advantages: it can be done regardless of skin conditions (eczema, dermatitis), is not affected by antihistamines, carries no risk of allergic reaction during the test, and can test for many allergens from a single blood sample. Skin prick tests give faster results and may be preferred by some allergists.
Hundreds of specific allergens can be tested, including common food allergens (milk, eggs, wheat, peanuts, tree nuts, fish, shellfish, soya), environmental allergens (grass pollen, tree pollen, dust mites, mould, animal dander), insect venom (bee, wasp), and latex. Your doctor or the test provider can advise which panel is most appropriate.
No. Unlike skin prick tests, allergy blood tests are not affected by antihistamines or other medications. You can continue taking all your medications as normal before the blood draw.
Results are typically available within three to seven working days, depending on the number of allergens tested and the laboratory used. Comprehensive panels with many allergens may take slightly longer.
