Short answer: there’s no single “longevity” blood test, but a set of reliably predictive biomarkers track the biggest drivers of lifespan and healthy aging — cardiovascular disease, metabolic disease, inflammation, organ function, and nutritional deficits. Below I list the most important blood biomarkers, why they matter, what to watch for, how often to test, and a few specific labs/services that can run them or give extra interpretation. Top biomarkers to watch (what they say and why) Lipids and atherogenic markers LDL‑C, non‑HDL‑C, triglycerides, HDL‑C — core CVD risk markers. High LDL/non‑HDL and triglycerides → higher atherosclerotic risk. ApoB and LDL particle number (LDL‑P or NMR lipoprofile) — better predictors of atherosclerosis than LDL‑C alone. Lp(a) — genetically determined independent risk factor for early atherosclerosis; test once in adulthood. Why: cardiovascular disease is the leading cause of death; these markers predict risk and guide treatment. Glucose metabolism Fasting glucose, HbA1c, fasting insulin, (or OGTT if indicated), HOMA‑IR. Why: dysglycemia and insulin resistance drive diabetes, cardiovascular disease, dementia — major longevity determinants. Inflammation and immune activation hs‑CRP (high‑sensitivity C‑reactive protein), IL‑6 (if available), fibrinogen, neutrophil:lymphocyte ratio. Why: chronic low‑grade inflammation (“inflammaging”) predicts multimorbidity and mortality. Kidney function Serum creatinine/eGFR, cystatin C, urine albumin:creatinine ratio (ACR). Why: CKD raises mortality and accelerates other aging pathways. Cardiac injury/stress markers NT‑proBNP (heart stress), high‑sensitivity troponin. Why: detect subclinical heart disease/risk even when other tests look OK. Liver function & metabolic health ALT, AST, GGT, albumin, bilirubin. Why: fatty liver and liver dysfunction are linked to metabolic disease and mortality. Complete blood count (CBC) & related Hemoglobin, hematocrit, white cell count, platelets, RDW (red cell distribution width). Why: anemia, elevated RDW, and abnormal WBC patterns associate with frailty and higher mortality. Micronutrients & related 25‑OH vitamin D, vitamin B12, folate, iron studies/ferritin. Why: deficiencies cause frailty, cognitive problems, and increased disease risk — many are fixable. Hormones relevant to aging Total and free testosterone (in men if indicated), estradiol (women as appropriate), SHBG, DHEA‑S, TSH/free T4 (thyroid). Why: hormone deficiencies or imbalances affect muscle, bone, metabolism, cognition and frailty. Growth factors and other aging markers (interpret with nuance) IGF‑1 — associated with growth/cancer/aging pathways (U‑shaped relationships). Homocysteine — elevated levels linked to CVD and cognitive decline. Omega‑3 index — low index linked to higher cardiac risk. Why: these are informative but typically need contextual interpretation. Emerging/biological‑age tests (optional) DNA methylation clocks (epigenetic age; e.g., GrimAge) and telomere length assays. Why: give an estimate of biological age and response to interventions — still evolving, useful for tracking but not diagnostic. What to test and how often Core annual panel for most adults: fasting lipid panel (or advanced lipoprotein testing if family history), fasting glucose and/or HbA1c, hs‑CRP, CMP (kidney/liver/electrolytes), CBC, TSH, vitamin D, B12, ferritin. Add apoB/LDL‑P and Lp(a) if personal/family history of premature CVD — Lp(a) can be tested once. NT‑proBNP/hs‑troponin if heart disease risk or symptoms. Repeat frequency: annually for stable people; every 3–6 months if you’re treating an abnormality or making major lifestyle/medication changes. Specific labs/services (why you might use them) LabCorp or Quest Diagnostics — broad coverage, clinical‑grade testing, widely used by clinicians; good for standard panels, Lp(a), apoB, NT‑proBNP, IL‑6 (available). InsideTracker — consumer‑facing panel + personalized interpretation and lifestyle recommendations geared toward performance/longevity; useful if you want actionable coaching with lab data. WellnessFX (or Vault by Wellness) — similar consumer service with clinician review and lifestyle guidance. Everlywell, LetsGetChecked — convenient at‑home collection kits for common panels (glucose, lipids, hormones); good for screening but limited for some specialized markers. OmegaQuant — specialty lab for the omega‑3 index (most clinical labs don’t run this). TruDiagnostic (or Chronomics) — DNA methylation clocks/epigenetic age testing if you want biological age tracking. TeloYears (if still available) or SpectraCell — telomere length assays (useful but more experimental/monitoring). Cleveland HeartLab and specialized CVD labs — for advanced inflammatory and atherothrombotic biomarkers if your clinician is managing complex CVD risk. Interpreting results and next steps Targets vary by age, sex, and risk. For example, LDL goals are lower for people with known CVD or diabetes. Many biomarkers have U‑shaped relationships with outcomes (very low or very high can both be bad), so context matters. Abnormal tests should prompt discussion with a clinician before starting supplements/medications. Lifestyle modifications (exercise, Mediterranean/whole‑food diet, smoking cessation, sleep, stress reduction, weight control) move many of these markers in the right direction. Caveats Some tests (epigenetic clocks, telomere length) are still emerging and should be used for tracking trends, not diagnostic certainty. Don’t over‑test without a plan — focus on biomarkers that change management. Always review abnormal results with a qualified clinician. If you’d like, tell me: your age, sex, major medical history, and what you can test easily (lab access), and I’ll propose a specific baseline panel and testing frequency — and which services to use for each test.

Short answer: There’s no single “best” service for everyone — it depends on whether you want clinician-led testing, convenience (at‑home kits), deep metabolomics or epigenetic clocks, and whether you want coaching. For general longevity tracking, InsideTracker is the best all‑around membership; complementary options are Quest/Labcorp (through your doctor or direct‑order services) for clinical-grade labs, LetsGetChecked or Everlywell for convenient at‑home testing, and Chronomics/TruDiagnostic for DNA methylation (epigenetic) age tests. Why these (briefly): InsideTracker — focused on longevity and performance. Combines blood biomarkers (metabolic, inflammatory, hormones, vitamins), optional DNA integration, research‑backed recommendations, and actionable personalized nutrition/lifestyle guidance. Good if you want an integrated, longevity‑oriented program and ongoing tracking. Quest Diagnostics / Labcorp — clinical labs with the widest test menu and most reliable access to specialist assays (NMR/LDL‑P, hs‑CRP, detailed hormone panels). Use through your provider or via direct‑order portals (DirectLabs, private physician). Best for medically rigorous testing and for ordering advanced markers. LetsGetChecked / Everlywell — at‑home blood/urine kits with nurse/telehealth support. Convenient for frequent monitoring (hormones, thyroid, basic metabolic and lipid panels). Good if you need convenience and privacy rather than a full clinician program. Nightingale Health (or other metabolomics providers) — if you want high‑resolution metabolomics / NMR profiling (detailed lipid subclasses and metabolic biomarkers) that can reveal early cardiometabolic risk beyond standard lipids. Chronomics / TruDiagnostic — specialized in methylation/epigenetic clocks (biological age estimates). Useful as a complementary measure of “biological age” change over time rather than replacing blood biomarkers. What to track for longevity (recommended core markers) Glycemic control: fasting glucose, HbA1c, fasting insulin (or HOMA‑IR) Lipids: full lipid panel + apoB or LDL‑particle number (NMR) if possible Inflammation: hs‑CRP, maybe IL‑6 if available Kidney & liver: creatinine/eGFR, AST/ALT Hormones & anabolic markers: testosterone (men), estradiol (women, cycle‑aware), DHEA‑S, IGF‑1 (if you’re tracking aging interventions) Nutritional: vitamin D, B12, ferritin/iron Hematology: CBC, ferritin (iron stores) Optional advanced: NMR metabolomics (LDL‑P), ceramides, homocysteine, cystatin C Epigenetic clock or telomere test as a complementary measure of biological aging How to use these services Start with a comprehensive baseline (InsideTracker or a physician‑ordered panel via Quest/Labcorp that includes the core markers above). Repeat most blood biomarkers every 3–12 months depending on risk and interventions; do epigenetic clock testing yearly or less frequently (changes are slower). Prefer clinical lab draws for accuracy when tracking small changes. Use at‑home kits for interim checks or convenience. If you want behavior coaching, choose a service that includes certified coaches or telehealth follow‑ups (InsideTracker, LetsGetChecked offer varying levels). If you tell me your priorities (most important: price, convenience, clinical rigor, coaching, or interest in epigenetic clocks/metabolomics), I’ll recommend a single best option and a sample testing cadence.

Short answer — for an ongoing, actionable longevity-focused lab membership I’d start with InsideTracker (best all‑around), add OmegaQuant for omega‑3 index, and consider an epigenetic clock provider (TruDiagnostic or Chronomics) if you want biological‑age tracking. Below are specific options and why each is useful. Best overall (membership + interpretation) InsideTracker — strongest for longevity: broad panel of cardiometabolic, inflammation, hormone and micronutrient markers; goal‑driven “Longevity” plan, personalized ranges and lifestyle/supplement recommendations, and scheduled retesting. Good if you want data + clear next steps. Clinician‑backed lab packages WellnessFX (LabCorp integration) — comprehensive clinical panels, physician review and telehealth support, easy for tracking trends over time. Good if you want clinician oversight with high‑quality lab draws. Quest Diagnostics (direct order or via a telehealth service) — wide test menu and easy repeat testing; pair with a clinician for interpretation. Convenient at‑home testing subscriptions LetsGetChecked — reliable at‑home phlebotomy/self‑collection kits and monthly/quarterly subscriptions for things like hormones, lipids, glucose. Good if you want frequent at‑home checks. Everlywell — convenient, lower cost at‑home kits for specific markers (vitamin D, thyroid, basic lipids). Less comprehensive counseling. Specialty tests you’ll likely want alongside a general membership OmegaQuant — gold‑standard omega‑3 index measurement (prognostic for mortality/cardiovascular risk). Cleveland HeartLab — advanced cardiovascular and inflammation biomarkers (Lp(a), apoB, advanced lipoprotein testing). SpectraCell — detailed micronutrient testing if you suspect deficiencies. TruDiagnostic (US) or Chronomics (UK/EU) — DNA methylation clocks (epigenetic age). These track biological age, but interpret with caution — useful for longitudinal tracking rather than single absolute values. TeloYears / LifeLength — telomere length testing (limited actionability; good to know but lower clinical utility than standard blood markers). How to choose If you want one subscription that gives broad, actionable longevity guidance: InsideTracker. If you prefer clinician oversight with standard clinical labs: WellnessFX or Quest + physician consults. If you want frequent, convenient home testing: LetsGetChecked or Everlywell. Add OmegaQuant and an epigenetic clock (TruDiagnostic or Chronomics) if you want targeted omega‑3 and biological‑age tracking. A recommended combo for thorough longevity tracking Base: InsideTracker membership (comprehensive blood biomarkers + personalized plan) Add: OmegaQuant once or twice yearly Optional: TruDiagnostic/Chronomics epigenetic clock yearly to track biological age trends Notes and caveats Epigenetic and telomere tests are evolving — they’re useful for tracking trends but have more variability and less standardized clinical actionability than routine blood biomarkers (lipids, HbA1c, CRP, etc.). Costs, available tests, and sample types vary by country; some services require lab draws while others are at‑home kits. Discuss abnormal results and medication/supplement changes with your clinician. If you tell me your country, budget, and whether you prefer at‑home kits or in‑lab draws, I can recommend the single best subscription option for your situation.

Short answer — several routine blood biomarkers are strongly associated with long-term health and mortality risk. They cluster around metabolic health (glucose/insulin), lipid/atherosclerosis risk, inflammation, kidney/liver function, hematologic status, micronutrients, and a few specialty markers and "biological age" tests. Below I list the most useful markers, why they matter, typical direction you want them to go, which test measures them, and a few services/companies that can run or interpret them. Important disclaimer: this is general information, not medical advice. Discuss abnormal results and treatment decisions with your clinician. Top-priority biomarkers for longevity (what to test and why) Hemoglobin A1c (A1c), fasting glucose, fasting insulin (or HOMA-IR) Why: chronic higher glucose and insulin resistance drive diabetes, vascular disease, dementia. Direction: lower within normal — A1c <5.7% is ideal; fasting glucose <100 mg/dL; lower fasting insulin and HOMA-IR indicate better metabolic health. How to test: standard lab panels. Lipids: LDL-C, non‑HDL, triglycerides, HDL — and better predictors: ApoB and ApoA1 Why: lipid-related atherosclerotic risk is the main driver of premature cardiovascular death. Direction: lower LDL-C/ApoB/non‑HDL; higher HDL (within reason); low triglycerides. ApoB is often a better single-number predictor than LDL-C. How to test: standard lipid panel + ApoB. Lp(a) (lipoprotein(a)) Why: genetically driven risk factor for atherosclerosis; important to know once. Direction: lower is better; elevated Lp(a) increases lifetime CV risk. How to test: single blood test. High-sensitivity CRP (hs‑CRP), and if available IL‑6 or fibrinogen Why: markers of chronic systemic inflammation predict cardiovascular events and mortality. Direction: hs‑CRP <1 mg/L is low-risk; higher indicates increased risk. Kidney function: serum creatinine, eGFR, and cystatin C when available Why: kidney disease strongly increases mortality risk. Direction: higher eGFR / lower creatinine (age-adjusted); cystatin C can detect impairment earlier. Liver enzymes: ALT, AST, GGT Why: fatty liver and liver dysfunction are linked to metabolic disease and mortality. Direction: lower or within normal range; elevated GGT often signals metabolic stress or alcohol use. Complete blood count (CBC) including red cell distribution width (RDW), hemoglobin, hematocrit Why: anemia and elevated RDW correlate with mortality and frailty. Direction: avoid anemia; lower RDW is better. Serum albumin and prealbumin Why: markers of nutrition / physiologic reserve; low albumin predicts worse outcomes. Direction: higher within normal range. Ferritin and iron studies (if iron disorder suspected) Why: both iron deficiency and iron overload have health consequences. Direction: context-dependent — treat deficiency; avoid excess. Vitamin D (25‑OH vitamin D) Why: low vitamin D associates with higher mortality and multiple chronic diseases. Direction: many experts aim for 30–50 ng/mL (discuss with clinician). Homocysteine Why: associated with vascular risk and cognitive decline in some studies. Direction: lower is better; treatable with B vitamins if elevated. Specialty or advanced markers / biological aging tests ApoB/ApoA1 ratio and advanced lipoprotein testing (NMR) Why: refines cardiovascular risk beyond standard lipids. Services: Quest, LabCorp, and specialized labs. Lipoprotein(a) — see above (genetic risk) Cystatin C (more sensitive kidney marker) High-sensitivity troponin (in some research settings) for silent cardiac risk D‑dimer, NT‑proBNP in selected cases (cardiac/clotting risk) Telomere length, epigenetic clocks (DNAm GrimAge, DNAm PhenoAge) Why: attempt to estimate biological age rather than chronological age. Research-useful but clinical utility is still emerging. Providers: TruDiagnostic (epigenetic clock tests), Zymo Research / Chronomics (some services), EpiAging technologies. Expect higher cost and evolving interpretation. Practical prioritization if you want to test only a few things Essentials: A1c (or fasting glucose), fasting lipid panel + ApoB, hs‑CRP, CBC, basic metabolic panel (creatinine/eGFR), ALT/AST, and vitamin D. If you have family history of early heart disease: add Lp(a) and advanced lipid testing. If concerned about biological age or prevention investment: consider epigenetic clock testing via TruDiagnostic or similar. Where to get these tests and interpretation (brands/services) Local clinical labs: Quest Diagnostics and LabCorp — widely available, accepted by clinicians and insurers. Direct-to-consumer / at-home kits: Everlywell, LetsGetChecked — convenient for many standard tests (A1c, lipids, vitamin D, thyroid). Interpretation + coaching platforms: InsideTracker, WellnessFX, and Thorne’s personalized lab services — they provide interpretation, personalized recommendations, and repeat testing plans. Continuous glucose monitoring and metabolic coaching: Abbott FreeStyle Libre or Dexcom + Levels app (Levels provides CGM-based coaching) — useful for understanding glucose spikes in non-diabetics. Epigenetic/biological-age testing: TruDiagnostic — focused on DNAm clocks and provides longitudinal reports; other players include Chronomics and Zymo Research (myDNAge). Specialty / research labs: Mayo Clinic Laboratories for complex panels; Quest/LabCorp also offer advanced tests (ApoB, Lp(a), NMR lipoprofile). How often to test Baseline and then annually for most markers if normal. Every 3–6 months if you’re making an intervention (starting statin, weight loss, diabetes therapy) or if values are abnormal. What actually improves longevity (brief) Lowering long-term exposure to high glucose/insulin, lowering atherogenic lipoproteins (ApoB/LDL), reducing chronic inflammation, preserving kidney and liver function, avoiding anemia and severe micronutrient deficiencies, and maintaining muscle mass and physical fitness. Proven interventions include lifestyle (diet quality, regular physical activity, adequate sleep, smoking cessation), control of blood pressure and lipids (including statins when indicated), and glycemic control in people with diabetes. Work with your clinician for medication decisions. If you want, I can: Suggest a compact “starter panel” tailored to your age/sex/family history. Point to which companies or test kits would be best for a specific marker (e.g., where to get ApoB, Lp(a), epigenetic clock). Explain target ranges in more detail for any one marker. Which would you like next?

Short answer — for most people wanting a single, longevity-focused lab membership I recommend InsideTracker (Ultimate plan) as the best starting point. It combines the widest set of validated blood biomarkers, an “biological age”/aging-focused scoring approach, personalized actionable recommendations, and retest scheduling. Why InsideTracker (primary pick) Broad panel of clinically validated blood biomarkers relevant to longevity (glucose/HbA1c, lipids, CRP, vitamin D, hormones, IGF‑1, etc.). Aging/“InnerAge” analytics to track biological age over time. Personalized nutrition, lifestyle and supplement recommendations tied to your labs. Built-in retest reminders and clear progress tracking. Good alternatives depending on your focus Levels (best for metabolic/longevity work focused on glucose): subscription CGM + app that helps you optimize diet, sleep and exercise to improve glucose variability — strong evidence that metabolic control matters for aging. NutriSense (similar to Levels): CGM membership with coaching options; good if you want more hand-holding. Chronomics or Elysium Index (epigenetic aging clocks): if your priority is tracking DNA methylation–based biological age, these services offer repeatable epigenetic tests and trend tracking. Viome (microbiome + host RNA): if gut health and personalized diet/substitution suggestions are a top priority for your longevity plan. Life Extension / direct lab access (if you want physician-guided labs and prescription options): good for ordering specialty tests (hormones, advanced lipids, micronutrients) with clinician support. AnyLabTestNow / DirectLabs / Personalabs (budget option for ad hoc repeat labs): lets you buy individual lab panels/ordering if you don’t want a subscription. A practical longevity “stack” Core: InsideTracker (comprehensive blood biomarker membership and re-testing). Metabolism: add Levels or NutriSense (CGM membership) for real-time metabolic optimization. Aging clock: test annually with Chronomics/Elysium to track methylation age. Gut: test with Viome if you want microbiome-directed diet/supplement guidance. What to check before you buy Biomarkers included (are the markers you care about covered? e.g., IGF‑1, CRP, sex hormones, HbA1c, lipids). Retest cadence, price of follow-up tests and membership cost. Actionability: are recommendations personalized and evidence-based? Access to clinicians or coaches if you want interpretation and treatment guidance. Ability to export your raw data for use in other tools. If you tell me your budget, whether you’re in the US (or elsewhere), and which aspects of longevity you care most about (metabolism, hormones, biological age, gut), I can give a tailored recommendation and exact plan.
