The best longevity
blood panel —
built by tier.

Standard bloodwork tells you whether you’re sick. A longevity panel tells you how fast you’re aging. Here’s every marker worth ordering, organized by priority — from the non-negotiable foundation through the advanced add-ons that separate longevity medicine from standard care.

Why standard bloodwork isn’t enough

The annual physical blood draw — CBC, basic metabolic panel, lipid panel — was designed to catch disease, not prevent it. Its reference ranges are built from population statistics that include millions of people with early-stage metabolic dysfunction. “Normal” on a standard panel means you’re not yet sick. It says nothing about trajectory.

The leading causes of death in people over 40 — cardiovascular disease, type 2 diabetes, cancer, neurodegenerative disease — share a common feature: they develop silently over decades. ApoB particles accumulate in arterial walls for 20 years before a cardiac event. Insulin resistance progresses through increasingly abnormal fasting insulin long before HbA1c crosses the prediabetes threshold. Subclinical inflammation drives vascular damage at hsCRP levels that a standard CRP test can’t even detect.

A longevity panel solves this by measuring differently. It uses tighter optimal ranges derived from centenarian studies and cardiovascular outcomes research, not population statistics. And it includes the markers standard care skips — the ones that predict where you’re headed, not just where you are.

The key distinction

Standard reference ranges answer: Are you sick? Longevity-optimal ranges answer: Are you aging faster than you should be? These are different questions, and the gap between “normal” and “optimal” is where most preventable disease begins.

Tier 1 — The Foundation Panel

01
Non-negotiable baseline — start here
10 markers · covers cardiovascular, metabolic, inflammation, and nutrient status · order once, then annually

These are the markers with the strongest evidence base for predicting cardiovascular disease, metabolic dysfunction, and all-cause mortality. If you have never been tested, this is where to start. If you’ve had standard bloodwork before, most of these were probably not on it.

MarkerWhat it revealsOptimal rangeIn standard care?
ApoB Total count of atherogenic particles — a more accurate cardiovascular risk marker than LDL-C <90 mg/dL Skipped
Lp(a) Genetically determined cardiovascular risk — elevated in 20% of adults, largely undetectable without testing <30 mg/dL Skipped
HbA1c 90-day average blood glucose — early metabolic risk signal well before diabetes threshold 4.8–5.4% Skipped*
Fasting Insulin Earliest marker of insulin resistance — rises years before HbA1c or glucose <6 μIU/mL Skipped
hsCRP High-sensitivity inflammation marker — predicts cardiovascular events, cancer risk, and biological age <1.0 mg/L Skipped
Homocysteine Cardiovascular and cognitive risk — modifiable with B vitamins; often dramatically elevated <10 μmol/L Skipped
Vitamin D (25-OH) Deficiency linked to cardiovascular disease, cancer, immune dysfunction, and all-cause mortality 50–80 ng/mL Skipped*
Lipid Panel LDL-C, HDL-C, triglycerides — cardiovascular baseline; interpret alongside ApoB TG <100 mg/dL Included
CBC + CMP Blood cell counts, liver enzymes, kidney markers, electrolytes — organ function baseline See individual markers Included
TSH + Free T3/T4 Full thyroid function — subclinical hypothyroidism is common and chronically underdiagnosed TSH 1.0–2.0 mIU/L Partial*

* HbA1c is ordered for diabetics or prediabetics, rarely in healthy adults. Vitamin D is ordered when symptoms appear, rarely proactively. TSH alone is standard; free T3 and T4 are almost never included in routine panels.

Order Tier 1 through Ulta Lab Tests

All 10 Tier 1 markers are available individually or bundled through Ulta Lab Tests — no doctor’s order required. The Longevity & Healthy Aging Essential Panel covers most of the foundation for under $200. ApoB, Lp(a), fasting insulin, and homocysteine can be ordered à la carte for $20–55 each.

Tier 2 — The Advanced Panel

02
Add once Tier 1 is established
8 markers · deeper insight into hormones, metabolic function, and cardiovascular risk

Once you have your Tier 1 baseline, these markers add meaningful depth. They’re not urgent on a first test — but they complete the picture and are essential for anyone actively optimizing rather than simply monitoring.

MarkerWhat it revealsOptimal rangePriority
Omega-3 Index EPA+DHA as % of red blood cell fatty acids — directly modifiable, strongly predictive of cardiac events >8% High
Ferritin Iron stores — both deficiency and excess are harmful; elevated ferritin signals inflammation and oxidative stress 50–150 ng/mL High
Testosterone (Total + Free) Muscle mass, energy, cognitive function, and metabolic health — declines predictably with age Varies by age/sex High (40+)
IGF-1 Growth hormone axis — too low impairs muscle and cognition; too high may accelerate aging 120–180 ng/mL Medium
Cortisol (AM) HPA axis function and chronic stress load — elevated cortisol disrupts metabolic health across every system 10–18 μg/dL (AM) Medium
GGT Sensitive liver marker — elevated with metabolic liver disease and alcohol stress; predicts cardiovascular mortality <20 U/L (M) / <15 U/L (F) Medium
Uric Acid Metabolic health and gout risk — elevated levels associated with insulin resistance, hypertension, and kidney disease <5.5 mg/dL Medium
Magnesium (RBC) The most important micronutrient for enzymatic function — standard serum magnesium is an unreliable proxy; RBC magnesium is meaningful 5.6–6.8 mg/dL (RBC) Medium

Tier 3 — Specialist Markers

03
Advanced insight with a specific hypothesis
For targeted investigation or comprehensive annual panels

These markers are valuable — but only once you have context from Tiers 1 and 2. They answer specific questions about cardiovascular risk architecture, inflammatory pathways, and metabolic function that the foundation markers can’t resolve on their own.

MarkerWhen to add it
NMR LipoProfile ApoB is elevated or you want particle size data — LDL particle number is a more granular cardiovascular risk assessment than LDL-C
Fibrinogen Clotting risk and chronic inflammation — useful when hsCRP is elevated to characterize the inflammatory picture further
Cystatin-C Superior kidney function marker — less affected by muscle mass than creatinine; use when eGFR sits in the 60–90 range
DHEA-S Adrenal function and hormonal aging — declines steeply after 30; low DHEA-S correlates with accelerated biological aging
IL-6 Direct inflammatory cytokine — add when hsCRP is persistently elevated and you want to characterize the inflammatory source
Lp-PLA2 Vascular-specific inflammation marker — high cardiovascular risk or family history with normal LDL-C
ApoA1 HDL function proxy — more meaningful than HDL-C alone; useful when ApoB/ApoA1 ratio is needed for risk stratification
Vitamin B12 Neurological health and methylation — essential for anyone on metformin, plant-based diet, or with elevated homocysteine

Normal vs. optimal — the ranges that matter

The single most important thing to understand about longevity testing is that standard reference ranges and longevity-optimal ranges are not the same thing. Standard labs flag values that are statistically outlying in the general population. Optimal ranges are built from a different question: what levels are associated with the lowest all-cause mortality and the best healthspan outcomes in long-lived populations?

A few examples where the gap is clinically meaningful:

MarkerStandard “normal”Longevity-optimalWhy it matters
HbA1c Below 5.7% 4.8–5.4% Metabolic disease is well underway at 5.6%
Fasting Insulin Below 25 μIU/mL Below 6 μIU/mL Insulin resistance begins well below the “normal” ceiling
hsCRP Below 3.0 mg/L Below 1.0 mg/L Cardiovascular risk rises meaningfully above 1.0
Vitamin D Above 20 ng/mL 50–80 ng/mL Most longevity-associated benefits appear above 50
Homocysteine Below 15 μmol/L Below 10 μmol/L Vascular and cognitive risk begins rising above 10

This is why uploading results to a tool that uses longevity-optimal ranges — rather than lab reference ranges — materially changes what you see. A standard lipid report might tell you everything is normal. A longevity-optimized analysis of the same data might flag elevated ApoB, borderline insulin resistance, and suboptimal Vitamin D simultaneously.

How to order your panel

You have two primary options depending on what level of oversight you want built in.

Superpower — Full service with physician oversight
Annual subscription that includes 100+ biomarkers, physician review of results, trend tracking, and a personalized protocol. The right choice if you want professional guidance built in. $199/year.

For most people starting out, the practical approach is to order Tier 1 markers through Ulta — either as a bundle or individually — get a baseline, and use the AgelessLabs AI tool to interpret the results. If you find markers outside optimal range and want ongoing physician-guided management, Superpower is a natural next step.

See the full breakdown of both services (plus InsideTracker and Function Health) in the Ulta Lab Tests review.

How often to test

Once in a lifetime
Lp(a)
Genetically determined — doesn’t change with lifestyle. Order once to know your baseline cardiovascular risk architecture.
Annually
Full Tier 1 panel
ApoB, HbA1c, hsCRP, Vitamin D, lipids, TSH, CBC, CMP. Annual cadence once markers are stable in optimal ranges.
Every 3–6 months
During active intervention
If you’re supplementing for Vitamin D deficiency, adjusting diet for insulin resistance, or on a statin — retest the specific marker you’re targeting to assess response.

The most valuable thing about longitudinal testing isn’t any single result — it’s the trajectory. ApoB trending from 95 to 82 mg/dL over two years tells a completely different story than a single value of 88. Build a record, and the data becomes increasingly useful over time.

Frequently asked questions

What’s the difference between a standard blood panel and a longevity panel?
A standard panel detects existing disease against population-based reference ranges. A longevity panel uses tighter optimal ranges and includes markers like ApoB, fasting insulin, and homocysteine that standard care routinely skips. The goal is identifying trajectory — where you’re headed over years or decades — not just current disease state.
What blood tests do doctors skip that matter most for longevity?
The most important omissions from standard primary care: ApoB (superior to LDL for cardiovascular risk), Lp(a) (genetic risk factor present in 1 in 5 adults), fasting insulin (earliest marker of insulin resistance), homocysteine (cardiovascular and cognitive risk), hsCRP (the sensitive version standard panels don’t use), and Vitamin D (deficiency is extremely common and rarely tested proactively).
What’s the difference between “normal” and “optimal” ranges?
Standard reference ranges flag statistical outliers in the general population, which includes many people with early metabolic disease. Optimal ranges are derived from centenarian studies and cardiovascular outcomes research. For example: standard HbA1c flags anything above 5.7% as prediabetic. Longevity-optimal HbA1c is below 5.4%. The difference between “not yet diabetic” and “genuinely metabolically healthy” lives in that gap.
How often should I get a longevity blood panel?
Annual testing for a healthy adult with no active interventions. If you’re managing a specific marker — supplementing for Vitamin D deficiency, adjusting diet for insulin resistance — retest that specific marker at 3–6 months to measure response. Lp(a) only needs to be ordered once; it’s genetically determined and doesn’t change meaningfully with lifestyle.
Do I need a doctor to order these tests?
No. Direct-to-consumer services like Ulta Lab Tests allow any adult to order any of these markers without a physician’s referral. You pay online, visit a Quest Diagnostics draw site, and get results in 24–48 hours. Not available in New York, New Jersey, Rhode Island, or Hawaii.
What should I do with my results once I have them?
Upload them to the AgelessLabs AI tool. It scores every marker against longevity-optimal ranges, identifies patterns across your full panel, and prioritizes what to address first. For any marker outside optimal range, the biomarker library has detailed pages on what the research shows, what interventions are evidence-backed, and how long it typically takes to retest.
