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

Private Health Decision Audits

It’s about evidence-based decision making under medical uncertainty. 

You don’t lack information.
You lack a way to interpret it.

This is where I come in.

You Are Flying Blind

You are expected to make decisions about your healthy longevity using:

An Evidenced Based Way to Make Decisions

I use a framework built on:

What you receive

This is not generic advice.
It is a decision model applied to your case.

$350

“One-time fee.”

45-minute one-on-one video evaluation. No hardware or app access included. This is a scientific consulting service, not a medical diagnosis.

This is for you if:

Start with a $89 Forensic Lab Audit

A focused analysis of your lab data.

The Audits are just one module of…

Vascular Signal Intelligence (VSI)

VSI is an analytical framework designed to help you map and optimize the stability and trajectory of your vascular age, the driver of healthy longevity.

Using the PILOT Infrastructure—a synthesis of N-of-1 clinical trial methodology and daily Pulse Wave Velocity (PWV) telemetry—we uncover the lifestyle inputs that slow down, or even reverse, your rate of vascular aging.

1. The Baseline

We strip away the noise. Using 2–4 weeks of continuous telemetry, we map your Pulse Wave Velocity (PWV) to establish a stable, statistical reference baseline of your vascular age.

2. The Intervention(s)

We introduce ONE input (e.g., Exrx, Diet, Supplement) at a time. We hold all other variables constant to isolate its direct impact on your PWV. This is a controlled test of your physiology.

3. The Validation

We measure the deviation against your baseline. If the PWV shift doesn't cross the statistical threshold, we reject the intervention. Only what works survives.
