WHAT SHOULD I MEASURE?

Measure what matters.

Most traditional medical testing is designed to help determine whether disease is present or whether a result falls within an established reference range.

That's important.

But if the goal is to live longer and preserve health and function as we age, we should also be asking:

What can we measure today that may help identify risk earlier?

What can we improve before disease develops?

And how do we know whether we're actually changing our trajectory?

Longevity testing isn't about ordering every available test.

It's about measuring what matters.

NORMAL ≠ OPTIMAL

“Normal” doesn't always mean there is nothing to improve.

Most laboratory results are compared with a reference range. Being within that range can be reassuring—but a reference range does not necessarily represent the level associated with the lowest long-term risk or the best health and physical function for a particular individual.

Longevity medicine looks beyond a simple normal/abnormal distinction.

We ask:

Is it favorable for long-term health?

Is there an opportunity to improve it?

Is it changing over time?

Could another measurement reveal risk that isn't apparent from routine testing?

Consider what a routine physical may not tell you:

A normal BMI doesn't tell you how much visceral fat, lean muscle or bone density you have.

Routine blood work doesn't measure your VO₂ max, aerobic capacity or strength.

A standard cholesterol panel may not include ApoB or Lp(a) or tell you whether atherosclerotic plaque is already present.

Your chronological age doesn't tell you how quickly you may be aging biologically.

And being free of symptoms doesn't necessarily mean that the early stages of cardiovascular disease, metabolic dysfunction, cancer or neurodegenerative disease are absent.

The goal isn't to chase perfect numbers.

The goal is to identify opportunities to improve health before they become problems.

ESTABLISH YOUR LONGEVITY BASELINE

You can't track a trajectory without knowing where you started.

A single measurement gives us a snapshot.

Measurements collected over time can tell us something much more useful:

Direction.

Is your visceral fat decreasing?

Is your lean muscle increasing?

Is your ApoB improving?

Is your VO₂ max increasing?

Are you getting stronger?

Is your pace of biological aging changing?

The objective is not simply to collect health data.

It is to use meaningful measurements to help answer:

Where am I now?

Where do I want to be?

Am I moving in the right direction?

MEASURE → UNDERSTAND → ACT → TRACK → REASSESS

WHAT SHOULD WE MEASURE?

There is no single “longevity test.”

A meaningful longevity profile looks at health from several different perspectives.

Not everyone needs every test. Age, sex, family history, lifestyle, previous results and individual risk all help determine which measurements may be useful.

BIOLOGICAL AGE

How are you aging?

Chronological age tells us how many years you have lived. Biological-age testing attempts to provide additional information about how your body is aging at a molecular level.

Epigenetic testing can provide information such as:

Biological Age
Pace of Aging
Organ-System Aging
Selected Epigenetic Biomarkers

RENU MD uses TruDiagnostic TruAge as part of its approach to biological-age testing.

The greatest value may not be simply receiving a biological-age number once—but establishing a baseline and following how these measurements change over time.

BODY COMPOSITION

Look beyond weight and BMI.

Two people can have the same height, weight and BMI and have very different health profiles.

DEXA can help measure:

Lean muscle mass
Total body fat
Visceral adipose tissue (VAT)
Bone mineral density

These measurements matter because longevity isn't simply about weighing less.

It is also about maintaining muscle, limiting harmful visceral fat and preserving bone as we age.

FITNESS & PHYSICAL CAPACITY

Measure what your body can do.

Physical fitness is one of the most important components of healthspan.

Yet it is rarely measured during a routine physical.

Objective measurements can help establish your current physical capacity and provide targets for improvement.

These may include:

VO₂ Max — aerobic capacity

Aerobic Endurance — ability to sustain aerobic work

Grip Strength — a practical objective measure of strength and physical reserve

Strength & Functional Capacity — the ability to continue performing the activities that matter throughout life

The objective isn't simply to exercise.

It's to build and preserve physical capacity for the decades ahead.

CARDIOVASCULAR TESTING

Look beyond a standard cholesterol panel.

Cardiovascular disease often develops silently for decades before a heart attack or stroke occurs.

Understanding cardiovascular risk may involve more than total cholesterol, LDL and HDL.

Depending on the individual, additional information may include:

ApoB

Lp(a)

Blood pressure and metabolic risk

Coronary Artery Calcium (CAC)

Coronary CT Angiography (CCTA)

Advanced plaque analysis such as Cleerly

Importantly:

A normal stress test does not mean plaque-free arteries.

Stress testing primarily evaluates whether coronary disease is producing significant limitations in blood flow during stress. It does not exclude the presence of coronary atherosclerotic plaque.

The goal is to better understand risk before the first symptom is a cardiovascular event.

CANCER EARLY DETECTION

Find cancer earlier.

Cancer screening works best when disease is detected before symptoms develop and before it has spread.

Established screening remains the foundation of cancer early detection.

Depending on age and individual risk, this may include screening for:

Breast cancer
Colorectal cancer
Cervical cancer
Lung cancer
Prostate cancer

Emerging technologies are adding another potential layer.

Multi-Cancer Early Detection (MCED) testing such as GRAIL Galleri is designed to detect a cancer-associated signal across multiple cancer types from a blood sample.

MCED does not replace established cancer screening.

It may provide an additional tool in a more proactive early-detection strategy.

Screen before symptoms.

The goal is to find cancer before it spreads.

LABS & BIOMARKERS

Go beyond “everything looks normal.”

Laboratory testing can provide important insight into cardiovascular, metabolic and overall health.

Depending on the individual, useful measurements may include:

ApoB · Lp(a) · LDL-C · HDL-C · Triglycerides

HbA1c · Fasting Glucose · Fasting Insulin

Liver Enzymes

and other biomarkers selected according to individual risk and health goals.

The purpose isn't to create the largest possible laboratory panel.

More data isn't necessarily better data.

The question is:

What information would actually change what we do?

FROM TESTING TO ACTION

A test result is only useful if you know what to do with it.

This is one of the reasons I created LYVYNG.

Your health isn't a collection of unrelated laboratory values, scans and reports.

LYVYNG is designed to bring those measurements together with your personal and family history, lifestyle and risks across the Four Horsemen:

Cardiovascular Disease

Metabolic Dysfunction

Neurodegenerative Disease

Cancer

The objective is to create an evolving picture of your health—and translate information into action.

IDENTIFY → MEASURE → ACT → TRACK → REASSESS

[ EXPLORE LYVYNG → ]

KNOW WHERE YOU ARE.

THEN CHANGE WHERE YOU'RE GOING.

Longevity testing isn't about chasing a perfect score or trying to perform every available test.

It's about identifying meaningful risks and opportunities, establishing objective baselines and following those measurements over time.

Measure what matters.

Act earlier.

Track the trajectory.
