Functional & Nutrigenomic Testing

At Spriggs Nutrition we can give you access to a wide variety of functional testing through trusted private laboratories. Typically, it is at your Report of Findings appointment, that any recommendations or referrals for tests would be made. Before any testing is completed an initial consultation with us must be completed –  this ensure we are able to recommend the most appropriate testing for your situation, assuming any is needed at all.


Examples of the types of tests available through us include:

  • Vitamins & minerals
  • Thyroid function
  • Liver function
  • Cholesterol
  • Hormones
  • Omega 6 : 3 ratio
  • Parasite, bacterial, viral infections
  • Gastrointestinal imbalances
  • Nutrigenomic testing
  • In clinic Live & Dry Blood cell analysis
  • Please note: we do not provide paternity testing

If you have existing/recent test results, including those via your GP, you are invited to bring these along to your appointment.

Why do we utilise testing?

In some situations being able to use functional testing can be incredibly helpful to add extra pieces to the puzzle to build a more complete clinical picture. It can be particularly useful to uncover the underlying cause for symptoms or conditions. Rather than focusing on the presence of specific markers functional tests give the opportunity for us to review the body at a molecular level, or assess how an organ or tissues are working.

The type of sample you would have to provide will depend on the test. Usually, either saliva, urine, stool or blood are collected which are sent directly to a laboratory for processing. Results will be sent to your practitioner, so they can discuss and explain them with but you will always be given a copy of the them. Costs do vary between tests, we will happily go through options with you and discuss this. However, we will always look to get maximum information from the minimum tests, if required at all.

Genetic Testing

Genetic testing can be used in two main areas. Firstly, in mainstream medicine such as via the NHS genetic or genomic testing is used to identify rare inherited health conditions, in these situations, you would be referred to a geneticist and based on the results offered genetic counselling. The world of genomics science now allows us to use our individual genetic information to support a preventative, proactive and personalised approach to health in a much more accessible way. We do this by working with specialist laboratories specifically, Lifecode Gx providing access to Nutrigenomic DNA test panels to inform how inherited health risks can be mitigated through personalised nutrition and lifestyle change. Our Registered Nutritional Therapist Helen Spriggs has fulfilled the requirements to be on BANT Nutrigenetic Counsellor Register (NgC) a condition of which is keeping up to date with the latest research and continuing professional development (CPD). Most recently Helen completed the Lifecode Gx Nutrigenomics Practitioner Programme in 2022.


Why would you use nutrigenomic testing? Our main focus is to identify the efficiency of specific pathways in your body that can be influenced by modifiable factors. We can think of genes being the seeds of our health and wellbeing, and the environment (food and other environmental factors, such as sleep, stress, physical activity and chemicals) that either help or hinder how some of our genes are expressed. Below are links to the specific nutrigenomic reports we can run from a simple cheek swab;

Nutrient Core ReportAnalyses how gene variants can affect food tolerance (and intolerance), appetite control and blood sugar balance, vitamin and mineral needs, detoxification ability, and susceptibility to inflammation and infection.

Hormones Report; Steroid hormones are a group of hormones derived from cholesterol that act as chemical messengers in the body. They are involved in the regulation of many physiological processes in both men and women, such as the development and function of the reproductive system, metabolism, inflammation and immune system.

Methylation Report; Methylation is the process of adding methyl groups, consisting of one carbon and three hydrogen atoms, to other molecules. It is involved in almost every metabolic process in the body, occurring billions of times every second in our cells and contributing to numerous crucial functions.

Histamine Intolerance Report; Histamine has many functions: as a neurotransmitter, communicating messages to and from the brain and nervous system; triggering the release of stomach acid to help digestion; and it can also be released after stress, injury or allergic reaction as part of the body’s immune response.

Oestrogen Balance Report; Oestrogen is one of the two major female steroidal sex hormones, the other being progesterone. Men also require oestrogen for producing sperm and maintaining libido, but at significantly lower levels. Oestrogen main role is to increase the growth and production of cells. It is responsible for the development of the female reproductive system and is also involved in maintaining bone density, blood clotting and affects hair, skin, mucous membranes and pelvic muscles.

Detoxification Report; Detoxification is the physiological removal of toxic substances from the human body. It is mainly carried out by the liver, and to a lesser extent the small intestine, kidneys and lungs. Substances such as nutrients, food additives, pesticides, medications, air pollutants, alcohol and hormones are transformed from being fat-soluble to water-soluble, allowing them to be more easily excreted from the body. The process occurs in two major phases: Phase I primes toxic molecules for deactivation and Phase II finishes the deactivation and prepares for elimination.

Nervous System Report; The nervous system supports the transmission of messages around the mind and body, enabling an individual to respond to their environment. A neurotransmitter is a molecule that carries signals between neurons and across nerve junctions (synapses). Excitatory neurotransmitters increase the likelihood a neuron will fire a signal, while inhibitory neurotransmitters have the opposite effect. In order for us to interact effectively with our environment these must remain in balance.

APOE Report; The Apolipoprotein E (APOE) gene is best known for its role in lipid (fat) metabolism by helping to remove cholesterol from the bloodstream. It can exist in three main forms known as E2, E3 and E4.

Thyroid Balance Report; The thyroid is an endocrine gland in the neck that produces two thyroid hormones – triiodothyronine (T3) and thyroxine (T4), and calcitonin. Thyroid hormones control the metabolism of almost every cell in the body, with wide-ranging metabolic, developmental and cardiovascular effects.

Athlete Report; DNA sequencing has opened the door to personalised approaches to health and fitness, enabling a more intelligent approach to training, recovery and performance. In this report, we present elements of your unique DNA profile that have been shown to affect athletic performance.

How much do these tests cost? All of the nutrigenomic reports start with a cheek swab – the fee for this is £99, then each requested report is £150, there is the option to select any five reports for a reduced fee of £732 + the £99. Please note: in most cases, prior to running nutrigenomic reports, an initial consultation must first be conducted to ensure we can recommend the most appropriate test/report and then provide truly tailored recommendations based on both your own case history together with the nutrigenomic reports. The fee for an initial consultation and the tailored recommendations is £180 in addition to any fees for testing.
