Why does XRGenomics not offer a DNA test for nutrition?

There are no clinical trials demonstrating that measuring your DNA can help decide whether you should eat more or less carbohydrate, protein or fat. While there are some tests for food allergies or caffeine these do not provide good enough advice for weight loss or nutrition for exercise. In short DNA tests for guiding nutrition can not help you plan your diet and thus are a waste of money. If and when valid nutrition DNA tests are discovered, we will incorporate them into the XRPredict+ product.

Why should I take the test?

Working out and sticking to an exercise regime can be hard enough so you want to ensure you are getting maximum benefit from all your efforts.

We believe that the best way of meeting your health and fitness goals is to follow tailored guidance. XRPredict+ combines your DNA analysis with our expert advice to provide you with just that. Your personalised report will define what benefits you can personally expect to achieve from exercise training and how to focus on the correct goals to maintain motivation.

It is our belief that it is far better to use the knowledge of your genetic make-up to tailor your exercise regime towards your goals, rather than to continue to follow a one size fits all approach which may not be working for you.

How old do I need to be before I can take the test?

Under the terms of the Human Tissue Act we are required to have consent before we can proceed with testing your DNA sample. Consent must be given or witnessed by an adult - someone aged 18 or older. If you are not yet 18 but wish to undertake the test now please contact us first by email - [email protected].

What if I’ve had a bone marrow transplant?

If someone receives a transplant of bone marrow the donor cells will always have different DNA from that of the recipient (unless the donor and recipient are identical twins). This means that our DNA test could show a mixed profile result and we would not be able to calculate a DNA result for your test.

How do I order the test?

You order the XRPredict+ test online at www.xrgenomics.com where we have a PayPal payment process. Here you will have the choice of paying via your PayPal account or, if you don’t have a PayPal account, using a credit card in the paypal system.

You will then be directed back to our website to complete an order delivery address form. After completion of the delivery address form you will need to complete one final step which is our questionnaire profile. This is a 30 question form, which will take no longer than 10-15mins to complete and provides us with important information we need to compile your personal report.

All customers will receive a confirmation order email plus an email with your shipping address, unique order ID and a link to contact us if you have any queries.

We will consider significant discounts for multiple purchases (family or business). Please contact us at [email protected] for trade prices or special bulk purchase deals.

What is included in the price?

The DNA sampling kit, the laboratory analysis of your DNA sample, as well as the report which includes your DNA results and personal, tailored advice from a world leading team of scientists and experts, is all included. 

How is the DNA sample taken? Do I have to go to a lab and be tested?

The DNA sample is taken using a simple mouthswab collection kit which will be sent to you in the post on completion of your order. Click here to read the instructions – . You do not need specialist help to take the sample - you can be done from the comfort of your own home.


Why do I need to answer a questionnaire?

The XRPredict+ profile questionnaire is a 30 question form, which will take no longer than 10 -15mins to complete and gives us information on your health and fitness goals along with other information we need to provide you with personalised advice.

Particular questions possibly requiring preparation include:

  • Your height (cm)
  • Weight (kg)
  • Waist size (cm),
  • Resting pulse rate (number per minute)
  • VO2max (ml/kg/min) - If you don’t have this specific information, just leave blank and move on to the next question.

Guidance instructions for questions requiring measurements will be given.

Together this information enables us to deliver appropriate and relevant feedback advice on your health and fitness goals. It is therefore important that you attempt to answer all questions as accurately as possible.

How long until I can expect my results?

Once our lab receives your sample we aim to return results within 3-4 weeks. When the test results become available, and assuming you have completed the questionnaire, we will email you an electronic report with your result along with your tailored health and fitness report. See our Terms & Conditions for further details on delivery of our services.

What is in the report?

In the XRPredict+ report we will review your physical characteristics, incorporating a review of those that need attention. We will then use your DNA test results and the information you gave in the questionnaire to provide you with recommendations on how to adapt your approach to your fitness to make it more effective. The report is set out as below:

  1. Analysis of your current situation
    1. Body composition
    2. Physical activity
    3. General health summary
  2. Aerobic fitness and the XRPredict+ DNA test
  3. Your DNA results
  4. Your personal goals
  5. Our recommendations for you
  6. Our top tips for you
  7. Further information / FAQ
  8. Scientific references

What do I do if I am a low responder?

If you are classed as a low responder you will not easily improve your fitness through aerobic exercise but you will still achieve other measurable benefits from exercise. Our report will talk you through what your results mean for you, how you should tailor your goals in line with this newly acquired knowledge, and how you should adapt your exercise routine to ensure you are getting the most out of it.

Our primary goal is to provide you with the key knowledge that will help you stay motivated and plan a healthier lifestyle.

What do I do if I am a high responder?

If you are a high responder you know that you should be seeing a clear and measurable improvement in your aerobic fitness levels. If you are not, then you know you need to adapt your workout routine to make it more effective, and we can provide advice on how to do that.

Can the test show me how to lose weight?

The DNA test itself will not help you lose weight, however applying the advice from the personalised report will help you to adjust your workout routine to make it more effective, thus increasing your motivation to keep on exercising. Weight loss is achieved quite simply by burning more calories than you take in, and therefore if you are better motivated to stick to your exercise plan then this will certainly help achieve your weight loss goals.

Can the test also measure ability to increase strength?

The XRPredict+ test currently only tests your ability to improve your aerobic capacity; in other words it only takes into account your ability to improve your VO2 max. As our research develops we will gain a greater understanding of how our genes impact other elements of our health and fitness.

What does improving my cardio by 15 percent mean?

15% is the average improvement over your baseline fitness that you can expect. Research has shown that baseline fitness and gains are not strongly related, so no matter your past activity, your gains would be estimated to be 15% improvement after a 10-20 week training program.
