Testing as a couple or family makes sense when you share meals: each person gets their own report and elimination plan, and you can plan swaps around the whole household at once. Order 2, 4 or 5 human tests together and you get a multibuy saving of 10%, 20% or 25% off each test.
Children can take part from age 6, with an adult aged 18 or over placing the order. Everyone takes their own hair sample at home, and nothing is posted to you, as your instructions arrive by email.
Why do households test together?
When one person changes what they eat, it affects everyone who shares the kitchen. Testing together turns that into a shared project rather than one person eating differently.
- Shared shopping and cooking: you can plan one weekly shop and one set of swaps that works for everyone.
- Mutual support: it is easier to stick to a 6–8 week plan when the people around you are doing the same.
- Fewer assumptions: your results may well differ from each other’s, even if you eat the same meals, so everyone gets their own starting point.
- One order: everyone’s instructions arrive at once, so you can take all the samples on the same day and start your plans in the same week.
How does the multibuy saving work?
The more human tests you order together, the bigger the saving on each one:
| Tests ordered together | Multibuy saving |
|---|---|
| 2 tests | 10% off each test |
| 4 tests | 20% off each test |
| 5 tests | 25% off each test |
For reference, a single Core test is £14.99 and a single Ultimate test is £24.99 before any multibuy saving. You can also spread the cost over 3 interest-free payments with Klarna or PayPal.

Does everyone get their own report?
Yes. Each person’s hair sample is tested separately, and each person receives their own digital report within 3–5 working days of the samples arriving, or within 48 working hours with priority results.
Every human report groups the items tested into high, medium and low response and includes a 6–8 week elimination plan and a printable food diary. That means each person works through their own high-response items, at their own pace.
Can children take part?
Yes, from age 6. An adult aged 18 or over places the order and takes the sample. Hair sampling is quick and needle-free, which makes it easy for children.
Children’s diets need extra care, because they need a wide range of nutrients to grow. Make one change at a time, always swap rather than simply remove, and keep the elimination stage as short as the plan allows. Our parent’s guide to food intolerance in children covers this in more detail.
Allergies in children need medical attention. If your child has swelling, hives or breathing difficulty after eating, particularly after milk, egg, nuts, fish or shellfish, get urgent medical help. Intolerance testing is not a substitute for allergy testing; the NHS explains food allergy symptoms and when to call 999.
When to speak to a GP
- You plan to remove a whole food group, such as dairy, from a child’s diet.
- You have concerns about a child’s growth, weight or appetite.
- Anyone taking part is pregnant, or has severe or persistent symptoms.
How do you take several samples at once?
Each person cuts 4–5 strands of hair close to the scalp, and dyed or treated hair is fine. The important thing is to keep everyone’s sample separate:
- Take one person’s sample at a time and fill in their form straight away.
- Keep each person’s hair with their own form, clearly labelled with their name.
- Never mix hair from two people, and wipe the scissors between samples.
Our step-by-step guide to taking your hair sample covers the details, including tips for children. If you are unsure how to send several samples, email our support team before you post.
How do you plan family meals around different results?
When everyone has different high-response items, the trick is to build meals from a shared base and add extras at the table.
- Find the common ground: list foods that are in the low group for everyone and build your main meals around them.
- Serve components separately: sauces, cheese, bread and toppings can go on the table so each person adds what suits their plan.
- Batch cook the basics: plain grains, roasted vegetables and simply cooked proteins fit around many different plans.
- Keep a diary each: one shared notebook gets confusing, so give everyone their own page.

Where hair sample testing fits
For households, hair sample testing is a simple way to give everyone their own starting point at the same time, without appointments or needles. Each person gets a clear plan, and you can organise meals around the results together.
The Core Intolerance Test tests 500 food items and is a straightforward choice for families focused on what goes on the plate. The Ultimate Intolerance Test tests 1,100 items, adding non-food, environmental and nutritional items, for anyone who wants a broader picture. If the family pet is part of the picture too, see our pet intolerance tests.
Every test comes with a 30-day money-back guarantee, and our support team is on hand by email, Monday to Friday, 9am–5:30pm.
Frequently asked questions
Can we take our samples on the same day?
Yes. Taking everyone’s samples on the same day keeps your plans in step. Keep each person’s hair and form clearly separate and labelled, and email our support team if you are unsure how to send several samples.
Can a child under 6 be tested?
Our tests are for children aged 6 and over, with an adult aged 18 or over placing the order. For younger children with symptoms you are worried about, speak to your GP or health visitor.
Will everyone in the family get the same results?
Not necessarily. Each person’s sample is tested on its own, so results can differ even between people who eat the same meals. That is why everyone gets their own report and plan.
Is the multibuy saving available on every test?
The multibuy saving applies when you order 2, 4 or 5 human tests together, giving 10%, 20% or 25% off each test. Pet tests are priced separately.
This guide is general wellness information, not medical advice. Our test uses bioresonance, a complementary (CAM) method; it does not diagnose allergies, coeliac disease or any medical condition. Speak to a GP if you have severe or ongoing symptoms.
