The Preventive Testing Ladder organizes screening into layers rather than treating every test as equally necessary. Start with routine blocking and tackling: cardiovascular measures, lipids, blood sugar, and liver and kidney function. Add specialty tests when they address a relevant question, such as gut, food sensitivity, or environmental exposure concerns. A further layer includes selected cancer, genetic, and epigenetic tests. Preventive imaging can then establish structural baselines and reveal changes over time. The mechanism is progressive coverage: each layer answers a different class of question and should earn its place through age, history, symptoms, and risk. The framework does not establish a universal schedule. Test choice, intervals, false-positive risk, radiation or procedure burden, and follow-up should be decided with qualified clinicians.
Origin
Malkin outlined what he called a comprehensive health plan, moving from basic laboratory measures through specialty tests, genetics, and preventive scans.
Core principles
- 01Build on basic health measures before specialty tests
- 02Match advanced tests to risk and purpose
- 03Use imaging to create longitudinal baselines
- 04Seek problems earlier without treating every variation as disease
How to run it
- 1
Cover the fundamentals
Establish routine cardiovascular, metabolic, liver, and kidney measures before reaching for advanced testing.
Pro tip Keep prior results so trends are visible.
Watch out Normal broad reference ranges do not answer every personalized question.
- 2
Add question-led specialty tests
Use specialty panels only when symptoms, exposures, or history create a specific question they can help answer.
Pro tip Ask what decision a positive or negative result would change.
Watch out More testing can increase ambiguous findings and unnecessary follow-up.
- 3
Assess inherited and biological risk
Discuss whether cancer screening, genetic information, or biological-age measures add useful context for your risk profile.
Pro tip Separate currently actionable results from future-looking information.
Watch out Genetic information may have privacy and interpretation implications.
- 4
Establish imaging baselines
Where clinically appropriate, use preventive imaging to create a baseline that later scans can compare against.
Pro tip The longitudinal comparison may be more useful than a single isolated image.
Watch out Imaging can generate incidental findings and is not automatically appropriate for everyone.
- 5
Set the review cadence
Agree which measures should recur, how often, and what findings would trigger follow-up.
Pro tip Use age, family history, prior findings, and clinician guidance rather than a fixed universal schedule.
Watch out Do not adopt the guest's suggested intervals as personalized medical advice.
In the wild
A healthy adult first consolidates routine laboratory trends with a clinician. Family history then justifies selected cancer-risk discussion, while a persistent digestive issue prompts one relevant specialty test. Imaging is considered separately for whether it would create a useful baseline and how incidental findings would be handled.
→ Advanced tests are connected to explicit questions instead of purchased as an undifferentiated bundle.
Common mistakes
Skipping the basic layer
Advanced tests should not distract from routine cardiovascular, metabolic, liver, and kidney monitoring.
Assuming every test is annual
Different tests need different schedules, and some may not be appropriate at all for a given person.
Ignoring false-positive costs
Broad screening can lead to anxiety, repeat imaging, procedures, and expense when incidental findings appear.
Is it for you?
Best for
Adults building a clinician-guided preventive health plan and deciding what belongs beyond routine blood work.
Not ideal for
Blanket testing without risk assessment, informed interpretation, cost awareness, or follow-up capacity.
From the transcript
“as part of like a I think a Comprehensive Health Plan you obviously need your just basic blocking and tackling your cardiovascular health your lipid…”
“I think some of the specialty test like we talked about gut microbiome food sensitivity environmental toxin but then you go into your genetic testing…”
“it's a diagnostic test that can track changes over time so even if you don't find something that is pinpoint disease you'll find changes over…”
