Case Study · The Real Root Cause Investigation

Four findings sat in her chart for years. Nobody read them together.

Every one of these results already existed. None of them were wrong. They had simply never been put on the same page by one person whose job was to ask what they meant as a set.

Shared with permission and fully de-identified — no name, no dates, no images, no documents.

What we will never publish

No member is ever named on this site without written permission, and clinical case studies are published de-identified regardless. That means no name, age to the year, location, dates of care, exact values, imaging, or report files. What you are reading is the reasoning — the part that is actually useful to you.

Values / dates

The four threads

Read one at a time, each of these is explainable away. Read together, they stop being separate problems and start being one.

Blood

A positive ANA that nobody had chased

An antinuclear antibody result on its own gets shrugged at constantly — it is common, it is non-specific, and it is easy to file under "we'll watch it." We did not file it. We treated it as the first thread and pulled.

Clotting

Portal vein thrombosis — in someone with no reason to clot

A clot in the portal vein is not a footnote. In a young person with no obvious risk factor it is a question that has to be answered: why is this body clotting, and what else is it doing that we haven't looked at yet?

Autoimmunity

An autoimmune liver panel and platelet antibodies

Run separately, each of these reads as a curiosity. Run together and read together, they stop being curiosities and start describing one immune system attacking on more than one front — which changes what you look for next.

Structure

Dilation at the left renal vein

The workup that came out of those questions found the structural piece: varicose dilation at the left renal vein — the compression pattern known as Nutcracker syndrome. Structural. Findable. Never once looked for, because nobody had connected the earlier findings.

Phase 1 · The Real Root Cause Investigation

Six layers of data, read as one document

Here is each layer, and what it contributed in this case.

Layer 01

Full history + symptom timeline

Every event, in order, with the dates. Surgeries, infections, stressors, medications, when each symptom started and what it followed.

In this case

The ovarian necrosis and the onset of orthostatic symptoms sit weeks apart in the same timeline. Sequenced properly, that is a vascular question, not a coincidence.

Layer 02

Blood chemistry + urine findings

Blood and urine are standard parts of the investigation. Clinical review connects inflammation, autoimmune and clotting findings, kidney and liver function, nutrient status and relevant endocrine questions; other tests are selective.

In this case

Clotting markers (PT, INR, dRVVT) and antiphospholipid antibodies are the difference between 'she has POTS' and 'she has an autoimmune clotting disorder producing POTS symptoms'.

Layer 03

DNA precision

The practice’s hair-sample bioresonance assessment of stressors—not gene sequencing or a molecular pathogen test.

In this case

This informed the practice’s individualized planning. It is not a validated diagnostic test for antiphospholipid syndrome, clots or vascular compression and cannot determine whether a clotting result is clinically significant.

Layer 04

Imaging and vascular assessment

Targeted structural imaging when the data points at a mechanical cause — venous compression, blood flow, organ perfusion.

In this case

Nutcracker syndrome is a structural finding. No amount of bloodwork finds it. You only order the scan if the rest of the data made you ask the question.

Layer 05

IRT — Integrative Response Testing

Direct in-body testing of how the system responds — which stressors, which organs, which interventions the body actually reacts to right now.

In this case

IRT informed the practice’s proposed treatment order. It does not confirm vascular or autoimmune diagnoses and does not replace laboratory criteria, imaging or specialist judgment.

Layer 06

The synthesis

Dr. Nicole reads all layers as one document and writes the root-cause map: what is driving what, what is downstream noise, and the sequence to unwind it.

In this case

This is the deliverable. Not more data — a mechanism, in plain language, with a protocol attached to it.

In progress · Day 3 of her protocol

Early signs, not a finished story

She came to us in a wheelchair, unable to stand. Treatment has only just started, so this is not a result — it is a first signal. For someone who could not stay on her feet, it is a big one. We will add the full case as it unfolds.

Before

120–130 bpm

Heart rate within moments of standing

Day 3

≈100 bpm

Heart rate while standing

Day 3

Up to 8 min

Standing, two days in a row

Her watch showing a heart rate around 100 while she stands, day 3 of her protocol
Day 3 · standing, heart rate ≈100. Shared with her permission.
“Yesterday and today I was able to stand for a couple minutes (up to 8 mins) and my heart rate stayed below/around 100bpm. For context: I can't stand without it jumping to 120–130bpm and getting super tired.”

How the Real Root Cause Investigation works

This is the first phase of Private Concierge. It is not more testing for the sake of it — it is the part almost nobody does.

01

Every result in one place, on one timeline

Phase 1 starts by collecting everything — old panels, imaging, notes, the tests three different offices ordered and never compared. Most of what we need already exists. It is just scattered across systems that never talk to each other.

02

Read for pattern, not for pass/fail

A lab report is designed to answer "is this outside the reference range?" That is the wrong question. We read for the story the markers tell together, in functional ranges, against the person's actual history.

03

Follow the thread that does not fit

The single finding that no one can explain is the most valuable thing in the chart. In this case it was an unexplained clot in someone with no reason to have one — and that is what led to the structural answer.

04

Name the mechanism, then build the protocol

Only once the mechanism is named does the plan get written. Everything starts day one on a six-week rotation, with a Week 6 re-evaluation against the data — not against a calendar.

Success should not cost you your health, your home, or yourself.

If your results keep coming back “normal” while you keep feeling worse, the next step is not another panel. It is someone reading the ones you already have.
