your GI-MAP results.

You paid ยฃ300+ for a comprehensive stool test. Don't let the results sit in a folder you don't understand. The interactive guide is being updated. Until it’s back, I read your GI-MAP with you, marker by marker, in Results & Plan (£295): plain English, clinical context, and clear next steps.

You have your GI-MAP results.
You don't know what they mean.

The GI-MAP is one of the most comprehensive gut health tests available. It's also one of the most confusing to read โ€” full of scientific notation, reference ranges, and marker names that mean nothing without clinical context. This guide was built to solve that problem.

๐Ÿ“„

You've run a GI-MAP privately

You ordered the test yourself or through a practitioner. The results arrived. You're not sure what to do with them.

๐Ÿค”

You've been told "it's all normal"

Your results came back and nobody explained them properly. You want to understand what you're actually looking at.

๐Ÿ”

You're investigating ongoing symptoms

Bloating, fatigue, brain fog, IBS โ€” you've tested but the dots haven't been connected into a clear picture.

๐Ÿ’Š

You want to know what to do next

Not just what your results say, but what the clinical next steps are โ€” specifically for your findings.

The interactive guide is offline while I update it. To have your results read, see Results & Plan.

"I have yet to see a case of persistent, significant symptoms where comprehensive functional gut testing found absolutely nothing. The symptoms are messages. The GI-MAP is how you read them โ€” but only if you can understand what you're looking at."
