Rather than diagnosing disease, it focuses on how your body functions and how you may respond to different health and lifestyle strategies. This type of testing may offer insight into: - metabolism and weight regulation - appetite and satiety - fat storage and insulin response - vitamin absorption, including B12, vitamin D and folate - detoxification pathways - stress response - inflammation and oxidative stress - skin ageing and collagen support - exercise response and recovery - sleep-related tendencies These are personalised, preventative insights that are not usually available from a standard blood test alone. ![](https://drcharlesworth.co.uk/images/trans/_standard/2019/lab-test.avif)Answers about how your body works ### What can genetic testing help you understand? Genetic and nutrigenomic testing can be helpful if you want clearer answers about how your body works and why certain challenges keep coming up. **Weight and metabolic function** If losing weight has felt unusually difficult, your results may help explain why. Testing can provide insight into how your body may process fats and carbohydrates, as well as patterns linked to appetite, satiety and metabolic efficiency. This can be especially useful if you want a more personalised and evidence-led approach to weight management. **Hormones and stress response** Your genetic profile may also offer useful information about how your body responds to stress and hormone fluctuations. For some patients, this helps build a clearer picture around symptoms such as poor sleep, emotional eating, low resilience during stressful periods or hormone-related changes. ![](https://drcharlesworth.co.uk/images/trans/_standard/1997/dna-strand.avif)Follow the science ### What else can the testing help reveal? **Nutrient absorption** Some people follow a healthy diet yet still struggle with low nutrient levels or symptoms linked to a deficiency. Genetic insights may help identify tendencies related to the absorption or use of nutrients such as vitamin D, vitamin B12, folate, omega-3 and antioxidants. **Skin ageing and regeneration** For patients interested in skin health and graceful ageing, testing may provide information on collagen support, inflammatory pathways, pigmentation tendencies, and recovery. This can help shape a more targeted plan for skincare, treatments and long-term skin maintenance. **Longevity and cellular health** Testing may also offer insight into broader areas linked to long-term wellness, such as oxidative stress, inflammation, detoxification and mitochondrial function. These findings can support a more personalised strategy for healthy ageing and preventative care. ## Who is this testing for? **This service may be suitable if you:** - want a more personalised, scientific approach to weight management - feel frustrated by ongoing symptoms despite normal blood test results - would like more insight into your hormonal or metabolic tendencies - want to optimise skin health and support healthy ageing - are looking to improve long-term wellbeing, energy and resilience - are interested in longevity and regenerative medicine - want a personalised nutrition and supplement plan It can also complement other services, including medical weight-loss programmes, hormone testing, and regenerative aesthetic treatments. ### How testing works **Step 1: Consultation** Your appointment begins with a detailed consultation. Dr Paulina will discuss your symptoms, medical background, lifestyle and health goals. This ensures the most appropriate testing panel is selected for your needs. **Step 2: Simple saliva swab** The test itself is quick and painless. A simple mouth swab is taken and sent to a specialist regulated UK laboratory for analysis. **Step 3: Personalised report** Once your results are ready, you will receive a detailed report explaining the key findings in a way that is clear and meaningful. Depending on the panel, this may include insights related to metabolism, nutrition, hormone patterns, skin health, exercise response and stress resilience. **Step 4: GP-led interpretation and plan** Your results are then reviewed with you by Dr Paulina, so you can understand what they mean in real terms. You will receive a tailored plan, which may include recommendations around nutrition, supplements, lifestyle, weight support, hormone balance, skin health and any appropriate follow-up testing or treatment. ### How genetic testing can support your wider health Nutrigenomic testing often helps connect the dots between different aspects of health and wellbeing. For example, it may support a more targeted approach to weight management, help inform hormone investigations or guide decisions around skin and regenerative treatments. By understanding your unique biology in more detail, it becomes easier to make choices that feel relevant, realistic and effective for you. Genetic testing ## Frequently asked questions - Is this the same as ancestry or disease-risk genetic testing? No. Nutrigenomic testing is different from ancestry testing and is not designed to diagnose genetic disease. It focuses on areas such as metabolism, nutrition, hormones, ageing and functional wellbeing. - Do my genes change over time? No. Your DNA remains the same throughout life, which means your results can continue to offer value over time. - Is the test painful? No. The test uses a simple saliva swab and is completely non-invasive. - How long do results take? Results usually take around 2 to 3 weeks, depending on the panel selected. - Is this testing useful for weight loss? It can be a valuable tool within a wider weight management plan. Testing may provide insight into metabolic tendencies, appetite patterns and how your body may respond to different dietary and lifestyle strategies. - Will this diagnose a medical condition? No. This testing is designed to provide personalised wellness information. If a medical investigation is needed, Dr Paulina may recommend additional blood tests or other appropriate assessments.
