Questions about the test

IgE is the antibody type involved in allergic reactions. When your immune system has learned to recognise something, like birch pollen or cat dander, it makes IgE against it. That is called sensitisation.

300 = whole allergens and their molecular components, from 150 allergen sources, plus total IgE. Some of the 300 are whole allergen extracts, such as sesame. Most are molecular components: single proteins from one source, such as Bet v 1 from birch pollen. One source can have several components, which is how 150 sources add up to 300 allergens.

A molecular component is one purified protein from an allergen source. Birch pollen, for example, is measured through Bet v 1, Bet v 6 and Bet v 7. Components help a doctor tell primary sensitisation from cross-reactivity: IgE to Bet v 1 plus IgE to Cor a 1 in hazelnut often reflects a birch-related cross-reaction, while IgE to hazelnut storage proteins such as Cor a 9 or Cor a 14 is specific to the nut. A doctor reads the pattern with your history.

IgE tests look for allergy-type sensitisation. IgG food tests, often sold as intolerance tests, mostly show which foods you eat regularly. The European Academy of Allergy and Clinical Immunology (EAACI) advises against IgG food tests for diagnosing food allergy or intolerance. We test IgE only.

No. Lactose intolerance, for example, is about digesting milk sugar, not the immune system. This test does not measure intolerance. A doctor can advise on the right test.

No. Sensitisation means your blood shows IgE to an allergen. Clinical allergy means you react to it. Many people are sensitised without symptoms. A doctor combines your result with your history to tell the two apart.

IgE blood tests are an established method used by allergy clinics. Like every test, they can show sensitisation that never causes symptoms, and occasionally miss one. That's why results are read alongside what you actually notice.

A few drops from a fingertip, enough to fill the small tube to the line. No needle in the arm.

Take the sample on a day you can post it, ideally early in the week, so it doesn't wait over a weekend.

No. You can eat and drink normally before the test.

IgE to pollen can be measured all year. Some people like to test during their symptoms so the result and the season line up in their notes, but it isn't required.

Age guidance for the kit is still being finalised. For a child, talk to your paediatrician first, especially after any reaction to food.

Results are typically 5 days after the lab receives your sample. We let you know when your lab report is ready.

Each value in kUA/L gets a class: Negative (below 0.3), Low (0.3 to 1), Moderate (1 to 5), High (5 to 15) or Very high (above 15). The class describes how much IgE was measured, not how strongly you react. They are a pattern to discuss with a doctor, not medical instructions. Our sample report page explains each part of the report.

That's common, especially with pollen-related cross-reactions. Don't cut out a food you tolerate based on a result alone. Take it to a doctor, who can judge whether it matters.

Yes. Your results come as a PDF lab report that lists every allergen and component with its measured value and class. You can print it or send it to your doctor.

See a doctor. If it is severe swelling or trouble breathing, call 112 in the EU or your local emergency number. Don't wait for a test result.

€300 for 300 allergens and components, €1 per allergen. Kit with return packaging, lab analysis and results are included. A doctor consultation is not.

No. One payment, one test.
