The Longevity Blood Panel: What to Test and Track

A longevity blood panel isn't an exotic test — it's a thoughtful selection of mostly ordinary markers, chosen because they track with the things that shorten healthspan: cardiovascular risk, metabolic drift, inflammation, and organ function. The value isn't in collecting a big number of markers once; it's in choosing a focused set and watching them move over years. This guide covers what a longevity panel typically includes and why — framed as markers to understand and track with your clinician, not a scorecard to grade yourself against.

What blood tests should you get for longevity?

There's no official "longevity panel," and anyone selling you a single definitive list is overstating what the science supports. But across the markers longevity- minded clinicians and researchers reach for, a few themes recur. Think in categories rather than a shopping list:

Cardiovascular risk — the biggest lever

Atherosclerotic cardiovascular disease is one of the largest drivers of shortened lifespan,¹ so a longevity panel leans hard here:

• ApoB — a direct count of the atherogenic particles most likely to lodge in an artery wall. Many lipid specialists consider it a sharper readout of cardiovascular risk than LDL cholesterol alone, which is why it shows up on nearly every serious longevity panel.
• Lp(a) — a largely inherited particle that adds cardiovascular risk independent of LDL. It's typically measured once to know your genetic baseline, since it's relatively stable over a lifetime.²

Metabolic health

Where cardiovascular risk often begins:

• HbA1c — an estimate of your average blood sugar over roughly three months, steadier than any single glucose reading and a core metabolic trend marker.³

Inflammation

Chronic, low-grade inflammation is a recurring theme in aging research:

• hs-CRP — a high-sensitivity measure of background inflammation.⁴ It's noisy in the short term (a cold or a hard workout moves it), which is exactly why the trend over many draws is what matters.

Organ function and the "quiet" markers

• Albumin — a liver protein and a broad marker of nutritional and overall status.⁵ It's unglamorous, but it's one of the inputs to the Levine PhenoAge biological-age model, which is part of why it earns a place.

Several of these — albumin, HbA1c-adjacent glucose, hs-CRP, plus kidney markers like eGFR and creatinine, the enzyme ALP, and the CBC index RDW — are the same routine labs the biological age test turns into a single PhenoAge number. That overlap is deliberate: a good longevity panel is built largely from markers you may already have, not proprietary extras.

Why this isn't about chasing "optimal" numbers

A caution worth stating plainly: avoid chasing a single "optimal" figure for any of these markers. Optimal ranges are debated, age- and sex-dependent, and vary by source and by lab. The reference range printed on your report is a statistical band, not a personal target, and treatment thresholds (like the ApoB goals that move with your cardiovascular risk) are a clinician's call informed by your whole picture — not a number to grade yourself against.

That's why each marker's own guide presents referenced, attributed ranges with their caveats rather than one magic value: read the range and context for ApoB, Lp(a), hs-CRP, HbA1c, and albumin on their own pages, and see the full menu in the blood test markers glossary.

Why the trend beats any single panel

Here's the part most longevity marketing gets backward: it sells you a dramatic one-time report. But a lone longevity panel is a dot, and a dot can't tell you whether you're drifting in a good or bad direction. The genuinely useful questions are longitudinal:

• Is your ApoB trending down since a dietary change or a medication your clinician started?
• Did hs-CRP settle back to baseline after that spike, or stay elevated?
• Is HbA1c creeping up a hundredth at a time across years — the kind of slow drift no single reading reveals?

"ApoB down 20% since March" is a story you can learn from; "ApoB is 88" is a data point with no context. Our guide to how to read your blood test results makes the case for direction over dot, and the biological age test explainer shows how a handful of these markers become a trackable score.

And here's the practical catch: you can only see the trend if the markers live in one place, on one timeline, in consistent units, over years. Scattered across a Quest portal, a LabCorp PDF, and a Function panel, the trend you most want is the one you can't assemble.

Where Libby fits

This is the job Libby is built for: drop in a lab PDF and every longevity marker — ApoB, Lp(a), hs-CRP, HbA1c, albumin, and the rest — lands on one timeline against the range on its own report, so you watch a trajectory form instead of reacting to a single noisy panel. It becomes a record you own and can export anytime, and it can track the Levine PhenoAge biological age from the routine markers you already have. Connected portal import and wearable integrations are on the roadmap — treat those as coming soon, not features to lean on today.

FAQ

What is a longevity blood panel? It's a focused selection of markers — cardiovascular (ApoB, Lp(a)), metabolic (HbA1c), inflammatory (hs-CRP), and organ/status markers (albumin, kidney and liver markers) — chosen because they track with healthspan. There's no single official list, and most of it is built from routine labs rather than proprietary tests.

How often should I get a longevity panel? Often enough to see a trend, not so often you're reading noise. Cardiovascular and metabolic markers are commonly tracked once or a couple of times a year; a mostly genetic marker like Lp(a) is often measured just once to establish your baseline. Your clinician can set a cadence for your situation.

Do I need to pay for an expensive longevity test? Not necessarily — a large share of a longevity panel overlaps with a standard metabolic panel, lipid panel, and CBC. The bigger determinant of value isn't the number of markers; it's whether you can track the ones that matter over time.

What's an optimal level for these markers? There isn't one universal answer. Optimal ranges are debated and depend on your age, sex, and overall risk, and treatment targets are a clinician's call. Each marker's guide gives attributed, referenced ranges with their caveats rather than a single figure.
