Dr. Lutz E. Kraushaar — The Double-Check Doc

You're Not Short on Information. You're Short on Interpretation.

Independent analysis of your laboratory results and cardiovascular records—for a better-informed conversation with your doctor.

You already have biomarkers, reports and recommendations. Understanding what the findings mean together is the real problem: where do they agree, where do they conflict and what remains uncertain?

I organize and interpret the evidence you submit against current epidemiological knowledge and deliver the result in a structured written report.

These services provide evidence analysis, not diagnosis, medical advice or treatment recommendations.

Why Your Results Are Difficult to Interpret

A laboratory value or risk estimate rarely provides a complete answer by itself. The real questions arise when you try to connect:

A Structured Evidence Review

I examine the submitted material using:

What Every Review Includes

This is not another automated risk score.

It is a structured interpretation of the cardiovascular evidence you already have.

The Evidence Map: Your relevant findings are organized into a coherent picture.
Contextual Interpretation: The results you submit are assessed against current epidemiological knowledge.
The Uncertainty Check: The report distinguishes between what the evidence supports, what it merely suggests and what it cannot establish.
The Written Report: You receive a clear PDF report to keep and use when discussing your situation with your physician.

€69–€399

“One-time purchase.”

Three fixed levels of analytical depth. You complete a short fit check first and receive a payment link only after the appropriate scope has been confirmed.

This is for you if:

You have cardiovascular test results but no coherent or contradictory interpretation.
You want to understand patterns, changes or disagreement between different markers.
You are preparing for a more informed discussion with your physician.
You prefer structured reasoning that makes uncertainty explicit.

Not Sure How Much Analysis You Need?

Choose between:

a review of one laboratory report, a longitudinal snapshot of recent results, and a broader cardiovascular decision review.

What Determines Your Review Level?

The appropriate level is determined before payment.

It depends on the amount of material, the context required and the complexity of the question—not on whether a result appears alarming.

If your proposed submission exceeds one level, you can either move to the appropriate level or reduce the documents and narrow the question.

1. How Much Material?

2. How Much Context?

3. What Question?

Cardiovascular Lab
Audit

"I have one lab test I don't fully understand."

One lab report (1 date)

Cardiovascular Risk
Snapshot

"I have several tests. Are things moving the right way?"

≤3 recent lab reports (incl. CAC)
What changed between tests, and whether it matters
Where markers disagree
4-5 page PDF report

Three questions for your doctor
€149 — One-time purchase

Not included: imaging review, extensive medical history or treatment scenarios.

Cardiovascular Decision
Review

I have conflicting reports & advice, and one decision to think through.

Up to 10 documents or 60 pages
Lab results, writtten scan reports and history
One defined prevention question
6-7 page PDF report
Detailed analysis & 1-page summary for your appointment
€399 — One-time purchase

Not included: raw images, DICOM files, ECG waveforms or unlimited document review.

All three services provide independent epidemiological evidence analysis for discussion with your physician. They do not provide diagnosis, medical advice, treatment instructions or emergency assessment.

Complete the initial fit check. I’ll confirm the appropriate scope and price before you receive a payment link.

About the reviewer

Lutz E. Kraushaar, DrPH, MSc.

I am an epidemiologist and public health scientist with more than 20 years of experience in cardiovascular research and evidence analysis.

My work has included research on vascular ageing and pulse wave velocity, publications in peer-reviewed journals including the European Journal of Preventive Cardiology and BMC Public Health, and research projects supported by the German government, the European Union and public institutions.

As the author of Double Check Doc, I critically examine medical studies, guidelines and health claims, with particular attention to risk interpretation, methodological limitations and the boundary between evidence and inference.

I apply the same discipline to every cardiovascular evidence review.

“The problem is not uncertainty. It is certainty the evidence has not earned”

My role is to distinguish what your evidence supports, what it merely suggests and what it cannot establish.
