Short answer: several well‑validated blood biomarkers predict future health and mortality — especially those that reflect metabolic (glucose/lipid), inflammatory, kidney, liver, and cardiac function. Below is a prioritized list of the markers that “matter” most for longevity, why they matter, and what to do about them. I also list a few testing services and companies that make it easy to get these tests and interpret them. Most important (high predictive value and actionable) Hemoglobin A1c and fasting glucose Why: chronic high glucose/diabetes is one of the strongest drivers of cardiovascular disease, renal disease and earlier death. Action: aim for normal glucose regulation (lifestyle, weight, exercise); treat diabetes aggressively if present. Fasting insulin / HOMA-IR (insulin resistance) Why: insulin resistance often precedes diabetes and links to metabolic disease and aging biology. Action: carbohydrate quality, weight loss, resistance + aerobic exercise, time‑restricted eating as appropriate. ApoB (or LDL particle number/LDL‑P) and comprehensive lipid panel (LDL‑C, HDL, TG) Why: atherogenic particle burden (ApoB/LDL‑P) tracks coronary risk better than LDL‑C alone. Action: diet, exercise, meds (statins/PCSK9/etc.) for elevated risk. Lipoprotein(a) — Lp(a) Why: genetically determined risk factor for premature atherosclerosis; important once in a lifetime test. Action: informs intensity of LDL lowering and specialist referral if high. High‑sensitivity C‑reactive protein (hs‑CRP) and IL‑6 Why: low‑grade systemic inflammation predicts cardiovascular events, frailty, and all‑cause mortality. Action: treat underlying causes (obesity, smoking, infections), exercise, diet, consider statins/other meds when appropriate. Kidney function: serum creatinine/eGFR and cystatin C Why: lower kidney function strongly predicts cardiovascular events and mortality. Action: blood pressure control, glycemic control, nephrology follow‑up for decline. Serum albumin Why: low albumin in older adults is a strong predictor of frailty and mortality (marker of nutrition/inflammation). Action: evaluate nutrition, inflammation, liver/kidney disease. Complete blood count (CBC) — hemoglobin, WBC, platelets; neutrophil:lymphocyte ratio (NLR) Why: anemia and abnormal WBC patterns are linked to poorer outcomes; NLR is an inflammation marker. Action: investigate causes, treat deficiencies, reduce inflammation. Cardiac biomarkers: high‑sensitivity troponin and NT‑proBNP Why: subclinical myocardial injury or cardiac strain predicts future heart failure and death. Action: cardiology evaluation if elevated, optimize CV risk factors. Liver tests: ALT/AST and GGT (and clinical assessment for NAFLD) Why: fatty liver and abnormal liver enzymes link to metabolic disease and worse outcomes. Action: weight loss, metabolic control, avoid hepatotoxins. Important nutrient / endocrine markers 25‑OH Vitamin D, B12, folate, ferritin/iron indices Why: deficiencies raise risk of frailty, poor healing, cognitive issues. Action: correct deficiencies with diet/supplementation under guidance. Thyroid (TSH, free T4; free T3 if indicated) Why: untreated hypo/hyperthyroidism increases cardiovascular and mortality risk. Action: treat appropriately; small abnormalities matter in older adults. Sex hormones (testosterone, estradiol) and DHEA (age/context dependent) Why: influence muscle, bone, metabolism; extremes associate with risk. Consider in symptomatic people. Action: measured and managed when clinically indicated. IGF‑1 Why: both high and very low IGF‑1 have been associated with adverse outcomes (U‑shaped). Action: interpret in context; not routinely needed for most people. Homocysteine Why: associated with vascular and cognitive risk; often responsive to B vitamins if elevated. Action: check if vascular/cognitive concerns and correct B12/folate if high. Emerging/experimental but interesting DNA methylation “epigenetic clock” (methylation age) and telomere length Why: correlate with biological aging; predictive value improving but still emerging and not yet a treatment target. Action: useful as research/monitoring tools; lifestyle improvements (exercise, diet, sleep) are still the main interventions. Plasma proteomics/metabolomics and advanced inflammation panels Why: can identify patterns linked to aging risk; mostly research / specialty use now. How often to test For generally healthy adults: baseline and then annually or every 1–2 years depending on age and risk. If you have chronic disease (diabetes, CKD, CVD) or abnormal results: follow your clinician’s recommended monitoring schedule. Where to get these tests (brands/services) Quest Diagnostics and LabCorp — broad test menus, widely accepted by clinicians and insurers; order standard labs (A1c, lipids, hsCRP, kidney/liver function, CBC, vitamins, ApoB, Lp(a) in many locations). InsideTracker — integrates lab results with personalized interpretation and lifestyle recommendations (diet, exercise, supplements); good for people who want actionable coaching tied to labs. Levels Health and Dexcom (CGM) — for detailed glucose dynamics using continuous glucose monitors; excellent for understanding post‑meal glucose excursions and personalized diet effects. TruDiagnostic — reputable provider of DNA methylation epigenetic age testing for people interested in biological‑age metrics (research/monitoring use). SpectraCell or specialized micronutrient labs — if you want a deep dive on micronutrient status beyond basic vitamin D/B12 testing. Everlywell / imaware — consumer/home testing options for some markers (convenient) but limited compared with full clinical labs. A few final practical points No single biomarker rules the day — context matters. Combinations (glycemia + ApoB + hsCRP + eGFR) give a much better picture of longevity risk than any single test. Many of these markers are modifiable through proven lifestyle changes (smoking cessation, exercise, diet, sleep, weight loss) and, when necessary, medications. Always review abnormal results with your clinician before starting or stopping treatments or supplements. If you want, tell me your age, sex, known medical conditions and which labs you already have — I can prioritize which tests would be most useful for you and recommend specific panels or testing services.
