There are two different types of allergy and sensitivity testing — and it's important to know which one is right for you.
A clinical allergy test (IgE test) is prescribed by a doctor and tests for immediate, potentially severe allergic reactions to substances like peanuts, shellfish, or bee stings. If you've been referred by your GP, or if you've experienced anaphylaxis or severe swelling, this is what you need — and your GP or an allergy clinic can arrange it.
A food sensitivity test is what we offer. It's a home test that identifies which everyday foods may be causing delayed, chronic symptoms — things like bloating, fatigue, skin breakouts, headaches, or low energy. It doesn't test for severe allergies, but it can be genuinely life-changing for people who have been struggling with unexplained symptoms for years.
If you're not sure which you need, a simple rule: if your symptoms are immediate and severe (within minutes of eating), see your GP. If your symptoms are delayed and chronic (hours or days later), our test is designed for you.
