Have you ever wondered why you still don’t feel well even when your blood tests look “within range”, or "normal"?
This is something I hear every single week.
Clients come in feeling tired, inflamed, hormonal, foggy, anxious, or just “not themselves”, and yet their standard blood tests tell them everything is fine.
Functional testing is often the moment things finally start to make sense.
Did you know that I can organise these deeper functional tests for you?
These tests help us understand how your body is working beneath the surface and why your symptoms keep showing up. When we can see the root cause clearly, your treatment becomes more targeted and your progress becomes faster.
The three main tests I recommend
1. MTHFR testing
For people with fatigue, PMS, anxiety, low mood, migraines, hormone imbalances, poor detox, fertility concerns, or long family histories of chronic illness.
Understanding your methylation efficiency helps us tailor your nutrition and supplementation so your energy, mood, detox pathways, and hormone processing all improve.
2. Hair Tissue Mineral Analysis
For chronic stress, irritability, gut issues, sleep problems, thyroid symptoms, restless legs, slow recovery, or suspected heavy metal exposure.
This test gives us a deep look at mineral stores, adrenal pattern, and the presence of toxic elements like cadmium, arsenic, mercury, lead, and aluminium. It is one of the most revealing tests available for chronic fatigue and inflammation.
3. Fasting insulin
For clients struggling with weight changes, inflammation, severe skin issues, energy crashes, sugar cravings, sleep disturbances, or hormonal shifts.
Insulin is one of the most important markers we can test, and it often explains symptoms long before glucose or HbA1c show problems.
While the three tests above form the foundation for most people, many clients also ask about:
• Gut microbiome mapping for bloating, IBS, constipation and diarrhoea.
• Organic Acids Testing for deep fatigue, mitochondrial dysfunction, brain fog, mood changes, and detox issues
These additional tests can provide even more clarity when needed.
Why functional testing matters
Functional testing isn't necessary for everyone, and I often don't recommend it to clients who don't need it. However, for some people, it helps them understand their symptoms rather than guess.
It gives you answers, direction, and confidence in your treatment plan, and it shows you on paper why you may be sick.
Most importantly, it helps you feel better faster, because we are no longer working in the dark.
If you have been feeling unwell, stuck, or overlooked because your standard blood tests are “normal”, functional testing may be the breakthrough you have been waiting for.
If you are ready for clarity and a personalised treatment plan based on real data, book a FREE discovery call and we can discuss which test is right for you.
