Intolerance Lab provides a proprietary, non-diagnostic reference service. You post us a small hair sample and we email you a structured reference report covering 700+ food, drink and everyday non-food entries.
This page sets out what the service is, what arrives in your inbox, and what it does not do.
The report is a structured digital reference document. It lists the entries we cover so you can keep it beside your own food diary and any conversations you have with your GP or a registered dietitian.
It is reference material to read alongside professional advice, not a substitute for it.
There is no kit to wait for. Once you order, your instructions arrive by email the same way your report will.
You collect 9–10 hairs, a few centimetres long, and post them to our UK laboratory in Jarrow using standard UK postage. Nothing is posted out to you first, there are no needles, and there is no appointment or laboratory visit to attend.
Not sure which foods to look at first? An at-home hair screen can help you narrow the list down before you start changing what you eat. See what the screen covers →
Your sample arrives at our UK laboratory and your report is emailed to you within 3 working days of it arriving.
The report covers 700+ reference entries: 350 foods and drinks, and 350 everyday non-food items. Platinum additionally supplies reference material covering preservatives and E-numbers, plus an 85-item informational vitamin and mineral guide. That guide is reference material only — it does not report your levels and it does not identify deficiencies.
Gold is £49 and covers 700+ reference entries. Couples and Family packs cover more than one person on the same terms.
Every report is delivered by email by our UK team, and a 90-day no-quibble satisfaction promise applies from the moment your report is delivered. That promise concerns your experience of the service.
Nine or ten hairs, a few centimetres long, are enough. Ordinary UK postage is fine and you can send them whenever suits you.
There are no needles and no clinic appointment. You post a small sample from home, and the report comes back by email, so nothing depends on getting to an appointment or waiting in for a delivery.
This proprietary reference service is non-diagnostic. It does not measure bodily reactions or diagnose intolerance, sensitivity, allergy, nutrient status or any medical condition. Speak to your GP about persistent symptoms; call 999 for a suspected severe allergic reaction.
Intolerance Lab is a UK business. Samples are posted to our facility at the Jarrow business centre and reports are emailed by our own team.
The service is available to anyone aged 6 and over. It is not offered during pregnancy or while breastfeeding — please speak to your GP instead.
If you are thinking about cutting gluten out of your diet, speak to your GP first. Reducing gluten before testing for coeliac disease can make that diagnosis harder, so keep eating gluten until you have had that conversation.
A food allergy is not the same as a food intolerance, and an allergy can be serious. If you have ever had a sudden or severe reaction to a food, speak to your GP, and call 999 for a suspected severe allergic reaction.
