Functional Testing
Step 1
Initial Consultation
We explore your health history, symptoms and goals.
Step 2
Clinical Assessment
Together we decide whether further testing would provide valuable information.
Step 3
Testing
If appropriate, your laboratory test is arranged.
To proceed with the tests, full name, home address, email address, phone number and date of birth (DOB) are required for me to register you as my patient. The tests are then sent to your address, where you can perform the sample collection in the comfort of your own home.
You can return the sample(s) via UPS/DHL/Royal mailing services, as indicated on instructions in your test kit, or in person directly to the lab.
Complete instructions can be found inside your test kit and summarised to your right
For shipping to and from Europe, there is an additional fee (between 25-55£) for mailing, which will be indicated on your paperwork in your test kit.
Step 4
Results Consultation
We'll review your results in detail, helping you understand what they mean—not just providing numbers.
Step 5
Your Personalised Plan
Nutrition, lifestyle and supplementation recommendations tailored specifically to your results and your health goals.
Step 6
Ongoing Support
Health is a journey, and we'll continue to refine your plan as your body responds.
Frequently Asked Questions
Do I need functional testing before working with you?
No. Many clients make significant progress using existing blood tests and a detailed clinical assessment alone.
Can you use my NHS blood test results?
Absolutely. Where recent, appropriate blood work is available, we'll use this before considering additional testing.
Are these tests evidence-based?
I only recommend laboratory tests that I believe add genuine clinical value. Testing is always selected carefully and interpreted within the context of current evidence, your medical history and your individual symptoms.
Can I order tests without a consultation?
No. To ensure testing is appropriate and interpreted correctly, all functional testing is recommended following an initial consultation.

A Note on Functional Testing
Functional testing is one piece of the puzzle—not the whole picture.
Results are always interpreted alongside your symptoms, medical history, medications, lifestyle and conventional medical investigations. Where appropriate, I work collaboratively with your GP and other healthcare professionals to ensure your care remains safe, evidence-informed and comprehensive.

Evidence-led testing. Personalised care. Real answers.
Stop guessing. Start understanding.
Have you ever been told your blood tests are "normal", yet you still don't feel like yourself?
Are you exhausted despite sleeping well, struggling with digestive symptoms that no one can explain, finding it difficult to lose weight, or navigating hormonal changes that leave you feeling unlike yourself?
Rather than relying on trial and error, functional testing allows us to understand why these symptoms may be happening.
Camilla carefully selects laboratory testing to uncover the underlying factors contributing to your symptoms—helping her create a treatment plan that is truly personalised to you.
This isn't about doing more tests. It's about choosing the right tests, only when they will genuinely improve your care.
Why Functional Testing?
Every person is unique.
Two people can experience exactly the same symptoms for completely different reasons.
While one person may be experiencing fatigue because of nutrient deficiencies, another may have blood sugar imbalance, poor gut health, chronic inflammation or hormonal changes.
Testing allows us to move beyond assumptions and make informed clinical decisions based on your individual physiology.
Rather than asking:
What supplement should I take?
.. we ask: What is your body trying to tell us?
Questions you may have asked yourself...
• Why am I always tired?
• Why can't I lose weight despite eating well?
• Why am I bloated after almost every meal?
• Are my hormones contributing to how I feel?
• Is stress affecting my health more than I realise?
• Am I actually absorbing the nutrients I'm eating?
• Could my gut be affecting my skin, mood or energy?If these questions sound familiar, functional testing may help us find the answers.
