Sensitivity Check is now Test My Food Sensitivity. In 2025, we brought our brands together under one home — same science, same team, same trusted results. If you've tested with us before, your account and results are still here. If you're new, welcome — you're in the right place.
About Sensitivity Check
Sensitivity Check has been one of the most trusted names in food sensitivity and intolerance testing since 2008, helping hundreds of thousands of customers across the UK, Australia, and beyond identify the hidden triggers behind their everyday symptoms.
In 2025, we brought Sensitivity Check together with our other trusted brands — including Test Your Intolerance, Test My Allergy, and Allergy Test — under the Test My Food Sensitivity family. Why? Because our customers told us they wanted one place to manage all their tests, one account to track their results, and one dedicated team to support them every step of the way.
By uniting our brands, we can now offer you a wider range of tests, improved results reporting, and the same quality and care that made Sensitivity Check a household name — all backed by our 100% money-back guarantee on sensitivity tests. If you are a returning Sensitivity Check customer, your journey continues here. Everything you loved is still available, now with even more options to support your health.
Not sure which type of test you need?
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.
