Testing that helps make sense of your symptoms
Tired of being told everything looks ‘normal’, when you know something feels off?
We choose from a panel of 60+ advanced lab tests to build a complete picture of your health and uncover the patterns, imbalances and underlying causes that are affecting how you feel.
We treat your body as one system
Rather than looking at symptoms in isolation, we use targeted testing to understand how different systems in your body may be interacting - from gut health and hormones to metabolism, stress and brain health.

Investigate where it matters
We choose from a broad panel of advanced functional tests to explore the deeper issues behind your symptoms and build truly personalised plans.
We work directly with partner labs, so we’re also able to offer many tests at preferential rates for Peach clients.

Conventional testing
Looks for disease
Gives you binary results (normal / abnormal)
Often stops at ‘everything looks normal’
VS
Peach functional testing
Looks for root causes of symptoms
Gives you nuanced insights (patterns, imbalances)
Helps explain why you may not feel fine
Testing that brings clarity, not confusion
Your body is unique - so is the data you need to understand it. Depending on your symptoms, history and goals, your practitioner will only select the tests that are most likely to result in meaningful insights. We never test for the sake of it.
Your practitioner will advise you on which tests are best placed to provide impactful, actionable information for your health.
Your top questions, answered
-
Yes, absolutely. If you’ve had NHS blood tests, private blood panels, or other testing done recently, please bring those results to your initial assessment. We can often extract useful insights from existing test data, though it’s worth knowing that we typically apply different reference ranges to standard blood markers, using tighter, evidence-based thresholds that reflect optimal function rather than just the absence of disease.
In many cases, we’ll also recommend supplementary functional testing to fill in gaps that standard panels don’t cover. For example, NHS blood tests don’t measure hormone metabolites, cortisol patterns across the day, or the composition of your gut microbiome - all of which can be critical for understanding chronic symptoms. Your practitioner will always be mindful of what testing is genuinely needed and will prioritise based on your symptoms, history, and budget.
-
Urine tests (like the DUTCH test) and stool tests (like the GI 360) come as home collection kits with clear instructions - you simply collect your samples and return them to the lab in the packaging provided.
If blood testing is required, you’ll visit a local phlebotomist (we’ll provide details of one near you) for a blood draw, or you can book a phlebotomist to come to your home if you prefer. All results come back to us, and we’ll schedule a detailed review appointment to walk you through everything.
-
Your practitioner will typically recommend between one and four tests depending on your symptoms and their complexity. As a guideline, the DUTCH hormone test costs £245 and the GI 360 gut test costs £340 - these are two of our most commonly used tests and both include the trade discounts we negotiate with the labs and pass on to you.
Overall testing costs usually fall between £150 and £500, though occasionally more extensive testing is recommended for complex, or chronic conditions. Your practitioner will always be mindful of budget and will prioritise the tests most likely to give you actionable insights. They'll be able to give you specific pricing for any other tests they recommend during your assessment. -
This depends on what tests you have had done - turnaround time for the laboratories that we work with varies.
As a rough guide, urine tests and many of the blood tests take two weeks, other tests (such as stool tests and methylation analysis) can take up to four weeks. Once the results have been received we will be in touch to schedule the next stage.
