What this test can and can't tell you
A genetic test measures wiring, the fixed underlying pattern. It doesn't tell you "what's happening in my body right now".
What it can tell you
What it can't tell you
Which nutrient pathways your body naturally supports well and which it asks for more of
Your current nutrient status, which changes with diet, absorption, and season
How you tend to metabolise caffeine, alcohol, and other common substances
How much of any specific food or drink you can tolerate right now
Whether you carry the genetic markers for coeliac risk or adult lactose tolerance
Whether you currently have coeliac disease, that's a diagnosis your GP makes
How efficient your body's detox pathways are at handling everyday environmental load
Your current detox demand, which depends on lifestyle, exposure, and gut health
The wider picture of how your genetics shape absorption, response, and clearance
How you'll actually feel after any particular meal, genetics is one input among many

What is nutrigenomics?
How your genes shape your response to food, the science behind the tests we offer.
Histamine Hub
What is methylation and why does it matter?
The methylation cycle activates B vitamins, regulates gene expression, and plays a direct role in histamine clearance.

A guide to the tiny genetic variations that make you unique, and what your report tells you about them.

Lifecode Gx
Lifecode Gx is a specialist nutrigenomics laboratory whose reports have been trusted by healthcare practitioners since 2017. They use genomics science to enable a preventative, proactive and personalised approach to health.
Research Backed Approach
Lifecode Gx gene interpretation is drawn from peer-reviewed nutrigenomics research.
Complete Customer Privacy
Genetics data anonymised by barcode from the moment it arrives, and deleted six months after testing.
Lifecode Gx is an independent laboratory. Tolerance does not see customer genetics data or report results.
FAQs
Shipping
4 questionsHow long does the whole process take?
Three to four weeks. The kit arrives in 1-2 days (UK) or 2-5 days (EU & US). When your cheek swab sample is returned to the lab with the pre-paid postage, lab processing takes 2-3 weeks. Your walkthrough call booking invitation follows shortly after. So, you receive the report and consultation within 3-4 weeks of your order.
Will you tell me when my sample has arrived at the lab?
No, the next you'll hear after posting your cheek swab sample is your booking invitation, about 2-3 weeks later. This is normal, your sample is not lost. You will receive some light, nutrigenomics content via email in the holding period. When your results arrive, you'll be fully up to speed.
How do I take the swab correctly?
Detailed step-by-step instructions come with your kit. If you'd like extra guidance, our written guide and short video walk through every step.
What can cause the test to fail?
It fails due to two reasons. Either the mouth swab hasn't been done properly, or the return storage instructions haven't been followed. It's important to follow all steps correctly.
Report & Walkthrough
6 questionsHow does the test work?
Taking your test
Your test is a simple cheek swab. It's non-invasive, takes minutes, and can be done at any time of day.
Before you swab:
- Don't eat, drink or smoke for at least 1 hour beforehand
- Swab thoroughly, as insufficient DNA is the main reason samples fail lab standards
Returning your sample:
- Place your swab in the tube with the stabilising capsule. Include the capsule whole, don't open it
- Complete and sign the consent form (write Tolerance under 'practitioner')
- Pop both in the prepaid return envelope and drop it in any post box (UK returns are free)
No special storage or transport requirements. Return it any day.
If your sample fails: The most common causes are a missing stabilising capsule or consent form. If it does happen, you'll get one free replacement kit, re-posted at no extra charge for UK orders.
What's included in the report?
Colour coded results
• Green: no variation of the gene, or the variant works in your favour
• Amber: somewhat negative effect
• Red: negative effect
Arrows show direction, meaning whether the variant turns that gene up or down.
What each result actually says
Not just "you have this variant" but what it does and what supports it. For example, a slower MTHFR result explains why methylation is affected, and what feeds the pathway. A GSTM1 deletion comes with the foods that support alternative glutathione routes.
What exactly does the Core Test analyse?
26 genes across nine categories.
Methylation: MTHFR, MTHFD1, FOLR1, SHMT1, DHFR, MTR, MTRR, FUT2, TCN2, PEMT, BHMT, CBS, CTH, GCH1, QDPR
Nutrition: BCO1 (vitamin A), VDR (vitamin D), HFE (iron)
Food response: HLA-DQ2 and DQ8 (coeliac risk), MCM6 (lactose), CYP1A2 (caffeine), ADH1B and ALDH2 (alcohol)
Detoxification: CYP1A1, CYP1B1, GSTM1, GSTT1
Each gene is reported with your genotype, a traffic-light indicator, and plain-language guidance for what supports the pathway.
Who will I speak to and how?
A trusted, registered practitioner who is trained on Lifecode Gx's Core reports. The video call is done through Zoom and takes thirty minutes with plenty of time for questions. If you are unable to do the preferred video call, let us know and we'll arrange an alternative method.
Can I add the Histamine test later?
Yes. If you'd like to add the Histamine test after taking the Core test, you can do so within 6 months without re-swabbing. Testing and practitioner appointments are chargeable. Drop us a message at care@gettolerance.com if you're interested.
How accurate is the genetic test?
The genotyping is at least 99.9% accurate. Anything that fails quality control is not reported. It appears as "no result" instead of a guess.
Science
6 questionsI have a cold and/or taking medication. Will my results be affected?
No. As we're testing the genetic code, which is fixed, the test is not impacted by illness, infections, medication, the food you eat or any food supplements you take. To avoid contamination of the sample, please abstain from eating / drinking for at least 1 hour before testing. Continue taking any medications and supplements as normal.
Is this a food intolerance test?
No. It does not measure your reaction to specific foods. It reads the genes that govern how your body handles them. It explains why you react rather than cataloguing what you react to. Be wary of any blood tests that claim to be food intolerance tests.
Will this diagnose coeliac disease or a food allergy?
No. What this test shows is whether you are genetically predisposed to certain conditions (like coeliac disease) or traits (like lactose tolerance). A genetic risk result is a reason to speak to your GP, never a diagnosis on its own.
What happens to my DNA and data?
All information is anonymised via barcode on arrival at the ISO-certified UK lab. Your report goes to you and to Lifecode GX's nutrigenomics expert, that's it. Your physical sample is destroyed after three months; genotyping data after six. Never sold, never shared, ever, with any third parties. You don't receive raw genome data.
Does it test for anything serious?
No. Only common variants are analysed, meaning ones present in at least 1% of the population. There are no rare disease markers and no frightening findings in the reports.
Should I get my children tested or will they have the same genes as me?
Every human has a slightly different genetic makeup. We inherit our gene variants from both parents so although you may have similar genes to your child, you won't have identical gene mutations. Our genes are the same from the moment we are born so you only ever need to do this test once in your lifetime and receive the data on your gene variants for life.

The right information so that you can take the next best step.
