Functional Testing
How does this work?
Because your symptoms deserve answers, not a one-size-fits-all approach.
If you have struggled with your health for years, digestive issues that never seem to resolve, unexplained fatigue, stubborn weight gain, or just the feeling that something is not quite right, you are not alone. Too often, standard tests come back “normal,” leaving you without answers. That is where functional testing can make a real difference. By looking deeper at your unique biochemistry, these tests can reveal hidden imbalances that may be driving your symptoms. With this knowledge, we can finally move beyond guesswork and create a personalised plan to help you feel well again.
​
The following are some of the key functional tests I commonly use in my nutritional programmes to identify underlying imbalances
Weight Loss
Continuous Blood Glucose Monitoring
If you’ve tried diets in the past but nothing seems to stick, the problem may not be your willpower, it could be your blood sugar balance. A Continuous Glucose Monitor (CGM) shows how your body responds in real time to the foods you eat, as well as lifestyle factors like stress, sleep, and exercise. This takes the mystery out of weight loss, giving you clear answers about what’s really driving cravings, energy crashes, and stubborn fat.
A Continuous Glucose Monitor (CGM) tracks your blood sugar 24/7, showing how your body responds in real time to food, stress, exercise, and sleep. This can be especially powerful if you’ve struggled with weight loss, sugar cravings, or energy crashes. Instead of guessing, you get clear feedback that helps you make smarter choices for better blood sugar balance, and more sustainable weight loss.
Food Intolerance Testing
For some people, food intolerances can quietly disrupt metabolism and fuel inflammation, making it harder to lose weight no matter how “healthy” your diet looks. By pinpointing these triggers, we can reduce inflammation and get your metabolism working with you, not against you.
Food intolerances can affect far more than digestion, they can impact energy, skin, mood, and even weight management. Identifying which foods your body struggles with allows us to reduce hidden inflammation, restore balance, and remove barriers to healing. For many clients, discovering and addressing intolerances is a turning point that helps them feel significantly better, often within weeks.
Gut Health
Comprehensive Digestive Stool Analysis
If you’ve lived with ongoing digestive discomfort, bloating, pain, unpredictable bowel habits, and never really had answers, this test can help uncover what’s going on. It looks at how well you digest and absorb food, checks for inflammation, and analyses the balance of “good” and “bad” bacteria in your gut. With this insight, we can design a plan that targets the real problem instead of just managing symptoms.
The Comprehensive Digestive Stool Analysis is an advanced test that looks at how well your gut is functioning. It provides a detailed picture of digestion, nutrient absorption, inflammation, and the balance of bacteria (both good and bad) in your gut. This information can be key to resolving long-standing issues like bloating, pain, diarrhoea, constipation, or unexplained fatigue. It helps us move away from “trial and error” and towards a targeted plan that restores balance and supports long-term gut health.
Food Intolerance Testing
Have you ever suspected that certain foods just don’t agree with you, but can’t put your finger on which ones? Food intolerances can trigger symptoms from digestive discomfort and fatigue to skin issues and stubborn weight gain. Testing helps take away the guesswork, giving us clarity on which foods might be holding you back so we can adapt your diet and help you feel better, faster.
Food intolerances can affect far more than digestion, they can impact energy, skin, mood, and even weight management. Identifying which foods your body struggles with allows us to reduce hidden inflammation, restore balance, and remove barriers to healing. For many clients, discovering and addressing intolerances is a turning point that helps them feel significantly better, often within weeks.
Healthy Ageing
Perhaps you’ve noticed changes in your energy, focus, or resilience as you’ve got older, but your GP tells you “everything looks fine.” Standard tests are often limited, missing the bigger picture. Advanced functional tests, on the other hand, give us a much more complete view of how your body is really functioning. I offer two highly detailed panels, one designed for women and one for men, that go far beyond routine blood work, giving us unparalleled insight into the areas most relevant to long-term health and vitality. These are far more comprehensive than a standard “well man” or “well woman” check, offering the kind of detail that can transform your health strategy.
​
Another option is the Annual MOT Blood Test, which offers a broad overview of health markers and is a great starting point if you want reassurance or a baseline for healthy ageing.
The Annual MOT Blood Test
Sometimes, difficulty losing weight is a sign of deeper metabolic issues. The Annual MOT Blood Test looks at markers like HbA1c (average blood sugar levels), which can show early signs of insulin resistance, often years before a diagnosis of diabetes. With this information, we can intervene early, supporting not just weight loss but also long-term health. The Annual Health Snapshot is a comprehensive blood test designed to give you a clear picture of your overall health. It measures 39 key health markers, including:
-
Cholesterol and triglycerides - insight into heart and cardiovascular health
-
HbA1c (diabetes risk marker) – showing average blood sugar levels over the past 3 months
-
Liver and kidney function – essential for detoxification and overall wellness
-
Vitamin D, B12 and folate – vital nutrients for energy, immunity, and mood
-
Iron status – detecting possible deficiency or anaemia
-
Inflammation markers – an early indicator of hidden stress on the body
-
Full blood count – assessing oxygen delivery, immune function, and more
This test is ideal if you want to: Get a broad overview of your health and identify imbalances early, track changes in your health year-on-year as part of a healthy ageing plan, take a proactive approach by spotting risk factors before they become bigger problems, gain practical insights to discuss with your GP or apply to your nutrition and lifestyle plan. The test is carried out via a venous blood draw by a qualified phlebotomist at a time and place that suits you. Results are usually available online within 7 days in a simple, colour-coded report, highlighting where action may be needed.
Women’s Health Test
This comprehensive test is designed specifically for women. It provides a detailed insight into the interplay between hormones, metabolism, nutrient status, and long-term health markers. It assesses over 100 biomarkers to create a personalised picture of your health, covering areas such as:
-
Hormonal balance (oestrogen, progesterone, testosterone, cortisol)
-
Thyroid function and metabolism
-
Inflammation and immune health
-
Cardiovascular risk factors
-
Nutrient levels and energy production
This test can help explain symptoms like fatigue, weight changes, brain fog, mood fluctuations, or disrupted sleep, and guide a targeted plan to support energy, vitality, and resilience through midlife and beyond.
