The Right Tests.
In the Right Order. With the Right Interpretation.

Most health investigations start too narrow and end too early. The Essential Trilogy gives you a complete clinical picture across three dimensions: blood chemistry, gut function, and metabolic performance.

my Optimal Range

Standard blood work checks whether you are sick. Functional testing checks whether your body is working the way it should be.

The difference between "normal" and "optimal" is where most chronic health issues hide. Your GP may tell you everything looks fine. But if your markers are sitting at the bottom of the reference range, your body is working harder than it needs to and you are feeling the effects.

The Essential Trilogy is the combination of three tests I run on every patient as a minimum when they first see me. Not one test. Not two. All three. Each test reveals a different system. Together, they provide a three-dimensional map of what is actually happening inside your body. Patterns between the three tests often reveal more than any single test on its own. This is how I identify what is driving the problem, not just which symptoms are present.

The Essential Trilogy

Comprehensive Blood Panel

The broadest single test available. Covers thyroid function, hormones (male and female panels), iron studies, inflammation, liver and kidney markers, blood sugar metabolism, and immune function. It is possible to get many of these markers through your GP, but in reality most doctors are not willing to run this level of testing. You can check with your GP, but it usually requires a minimum of two visits, one to request the markers and one to collect the results, and many GPs will only agree to part of the panel. A private panel is available here, delivered direct to you, with every marker included.

Advanced Stool Test

A comprehensive DNA-based analysis of your gut. Identifies bacterial overgrowth, parasites, fungal imbalance, intestinal inflammation, gut barrier function, immune defence, digestive capacity, and occult blood (AU test). This is a must for every patient I see, regardless of how well they think their gut is travelling. Some of the worst stool test results I have seen have come from people who told me their digestion was fine. The gut drives more than digestion. It drives immune function, inflammation, hormones, mood, and energy. You cannot skip this test and expect the full picture.

Organic Acids Test (OAT)

A urine-based metabolic test that measures over 70 markers across energy production, neurotransmitter metabolism, detoxification, nutrient status, and microbial overgrowth. This is the test that shows how your body is functioning at a cellular level. It reveals what blood work and stool testing cannot see.

Do I need all three?

You can still get good information out of each test individually. But the best depth of discovery comes from running all three together. I run all three on every patient as a minimum. Each test reveals a different dimension of your health. Blood work shows the systemic picture. The stool test shows the gut picture. The OAT shows the metabolic picture. Patterns across all three tests are what allow me to identify root causes and sequence treatment correctly. If budget is a concern, you can stage them over a few weeks, but the goal is all three.
