Assessment first, testing second

Supportive testing

What testing can tell us, what it cannot, and when it is worth considering.

One thing to say before anything else on this page. Testing is never a standalone service with me, and it is never a standard starting point for anyone. It is offered where it is clinically appropriate, it is discussed on a discovery call at most, and it is never recommended until a thorough assessment has been conducted.

What testing is for

Doing everything right and still not seeing results?

Ever feel like you’re doing everything right and still not seeing the results you’d expect? That’s often where supportive testing earns its place. Rather than guessing at what might be going on, supportive testing may be recommended to assess nutritional imbalances and inform personalised diet and lifestyle recommendations to support your wellbeing, so that what I suggest is built around your own results, not a general template.

I don’t sell tests on their own. Testing may well be discussed on a discovery call, but it is never recommended until a thorough assessment has been conducted, so that we both know whether a test would actually tell us anything useful. Plenty of people don’t need one. And where something is the kind of test your GP might be able to arrange through your surgery, I’ll say so, so that you can ask them before you pay for it privately. Whether it is available to you is their decision, based on what is clinically appropriate in your case, and it is never automatic.

Taking the guesswork out

What testing is, and what it is not

With supportive testing, I’m not relying on trial and error. Once I understand where the nutritional imbalances are, I can build a plan around your own results, so the plan starts from what is actually going on for you.

Supportive testing is not diagnostic testing, and I’m always upfront about that. It isn’t used to test for the risk, presence, cause or extent of any disease, disorder or injury, and it isn’t used to diagnose or to treat. What it does is give you a clear baseline to understand where things stand for you now, flag anything worth raising with your GP, and track genuine progress as you make changes. If a result comes back outside the normal range and looks like it needs a medical opinion, I will tell you plainly and refer you to your GP, and with your consent I will write to them and share the result so they have it in front of them.

Nutrigenomic testing

Your genes do not decide your health, but they do influence how your body handles certain things day to day, how efficiently you process folate and the B vitamins, how quickly you clear caffeine, how you respond to different types of fat, and how well you manage oxidative stress and inflammation. It is one reason two people can follow the same sensible advice and get quite different results from it.

This is a one-off saliva or cheek swab test, done once rather than repeated, since your genetics do not change. I am accredited through the Lifecode Gx Nutrigenomics Practitioner Programme and use their panels, which are built for a practitioner to interpret properly instead of handing you a long list of alarming-looking variants with no context.

What it gives us is a better informed starting point, and it earns its place most where you have already made sensible changes and they have not worked the way you expected. It tells us about tendencies rather than certainties. It does not predict, diagnose or rule out any condition, and nothing it shows changes the medical care you are already under. If what you want to understand is your risk of developing a particular disease, that is a genetic counselling question rather than a nutrition one, and the right person to see is a medical practitioner, not me. Used properly, it means less trial and error and a plan built around how your own body actually works.

Energy, weight and mood

Thyroid testing

Your thyroid is small, but it does a big job, helping regulate energy, weight, mood, metabolism and cholesterol. Standard testing usually starts with TSH, which is a reliable first check, and a fuller panel adds detail about what sits behind that result.

If you’re dealing with fatigue, unexplained weight changes, low mood, hair loss, feeling the cold more than most, or irregular periods, a fuller thyroid test can help us understand what is going on. Alongside TSH, we can look at:

  • TSH (thyroid-stimulating hormone): made by the pituitary gland in the brain, it tells your thyroid how much hormone to produce. It tends to rise when the thyroid is underactive and fall when it is overactive.
  • T4 and Free T4: T4 is the main hormone your thyroid makes. Free T4 is the portion not bound to proteins in the blood, so it reflects what is available for your body to use.
  • Free T3: the active form of thyroid hormone, the one your cells actually respond to. Most of it is made from T4 in tissues such as the liver and kidneys, rather than in the thyroid itself.
  • Reverse T3: an inactive form of T3, also made from T4. Levels can rise during illness, significant stress or calorie restriction. Its value outside these situations is still debated, so I interpret it with care and alongside your other results, never on its own.
  • Thyroid antibodies (TPO and thyroglobulin antibodies): these show whether your immune system is targeting your thyroid, the most common cause of an underactive thyroid in the UK. They can be present before hormone levels change.
  • Selenium, iodine and zinc: iodine is the building block of thyroid hormones, and too little or too much can affect how your thyroid works. Selenium is needed for the enzymes that convert T4 into active T3, and zinc is also involved in thyroid hormone metabolism.

Understanding how your thyroid is working helps build a plan around what is going on, instead of guessing.

Digestion and inflammation

Gut health testing

Your gut microbiome plays a bigger role in overall health than many people realise, including in how your body handles inflammation, which sits closely alongside cardiometabolic health rather than apart from it. Where it is relevant to the work we are already doing, a stool test can assess the balance of bacteria and yeasts in your gut and inform personalised diet and lifestyle recommendations to support your wellbeing.

It is used as one part of that work rather than as a gut health service in its own right, and where digestive symptoms need investigating, that is a conversation for your GP rather than a test from me.

Other tests

Other tests I may discuss with you

Each of these is only ever considered after a thorough assessment, and only where it would genuinely tell us something useful.

  • Metabolic baseline testing

    For a genuinely stuck picture, a broader test combining blood, urine and genetic markers looks at how your body produces energy, copes with stress and manages the everyday load placed on it. It tends to suit people with low energy, ongoing fatigue or mood changes that haven't shifted with the usual approaches.

  • Adrenal and stress hormones

    A simple saliva test checking cortisol and DHEA, the hormones behind your energy, mood and stress response. Chronic stress has a genuine, well-documented link to blood pressure and blood sugar control, so it is directly relevant to your cardiometabolic health.

  • Hormones through the menopause

    A comprehensive saliva test tracking oestradiol, progesterone and testosterone across a full cycle, for those who are premenopausal or perimenopausal and not currently on hormone therapy. It can help make sense of fatigue, low mood, sleep changes or difficulty losing weight.

  • Cardiovascular fitness and performance

    For anyone training regularly, a look at key hormones such as testosterone, oestradiol, TSH and Free T4, alongside a full blood count covering nutrient status, liver and kidney function, iron levels and protein balance.

  • Well-woman health check

    A comprehensive blood test covering thyroid and hormone health alongside markers of heart and liver function, including red and white blood cells, iron, vitamins B12, D and folate, magnesium, and the female hormones tied to the menopause transition.

  • Men's health MOT

    A clear overview of energy, hormones, heart and liver function in one test, giving a baseline you can track over time, including cholesterol, inflammation, iron, vitamins B12, D and folate, thyroid function, magnesium and testosterone.

Costs

What testing costs

Testing is charged separately from your programme, at cost, with no commission taken from any laboratory, and I will always tell you what a test costs before anything is ordered. Where something is the kind of test your GP might be able to arrange through your surgery, I will say so, so that you can ask them first. Whether it is available to you is their decision, based on what is clinically appropriate in your case, and it is never automatic.

Full programme prices are on the Ways to Work Together page.
