Short answer: several routine blood tests are strongly associated with longevity (mortality risk) and are useful because they’re actionable. The most important are measures of cardiometabolic health, inflammation, kidney and liver function, anemia/nutritional status, and certain cardiovascular-specfic markers. Below I list the most evidence-backed biomarkers, why they matter, and practical testing options. Most important biomarkers (what to check and why) Lipids: LDL-C, non‑HDL, triglycerides, HDL — strong predictors of cardiovascular risk, the single biggest driver of premature death in most populations. Measure ApoB if you want a more direct count of atherogenic particles (better than LDL in many cases). Lp(a) — genetically determined risk factor for early atherosclerosis; one-time test is useful because it’s not changed much by lifestyle and influences treatment decisions. HbA1c and fasting glucose (plus fasting insulin when possible) — glucose control and insulin resistance strongly predict diabetes and cardiovascular risk; HbA1c gives 2–3 month average. hs‑CRP (high‑sensitivity C‑reactive protein) — marker of systemic inflammation; elevated levels predict cardiovascular events and all‑cause mortality. Kidney function: creatinine/eGFR and cystatin C (if available) — chronic kidney disease markedly raises mortality and cardiovascular risk. Albumin (serum albumin) and total protein — low albumin is a strong, independent predictor of frailty and mortality in older adults. Complete blood count (CBC): hemoglobin/hematocrit, white cell count, RDW — anemia, elevated WBC, and higher RDW are associated with worse outcomes. Liver enzymes: ALT, AST, GGT, bilirubin — abnormal liver tests can mark fatty liver or other conditions linked to metabolic disease and mortality. Vitamin D (25‑OH vitamin D) — low levels associate with worse outcomes in many observational studies (and are easy/cheap to correct if low). Homocysteine — elevated levels linked to cardiovascular disease and cognitive decline in some studies; may prompt B‑vitamin evaluation. Inflammatory cytokines (IL‑6) and fibrinogen — stronger inflammatory predictors than CRP but less widely available; useful in research/complex cases. Omega‑3 index — low omega‑3 RBC content associates with higher cardiac mortality; actionable via diet/supplementation. Coagulation markers (fibrinogen, D‑dimer) — higher levels linked with thrombosis and mortality in some cohorts. Advanced/biological‑age tests (contextual, not yet standard care) ApoB (if not already done), advanced lipid testing (particle number/size) — refines risk beyond standard lipids. Epigenetic clocks / DNA methylation age (e.g., tests from TruDiagnostic) and telomere length — estimate “biological age”; promising but interpret with caution (still emerging utility). p16, senescence markers — research tools, not routine. How to use these tests Focus on the core set first: lipid panel + ApoB or non‑HDL, HbA1c, fasting glucose (± insulin), hs‑CRP, CBC, CMP (creatinine/eGFR, liver enzymes, albumin), vitamin D, and Lp(a) once. These identify the biggest modifiable risks. Interpret results in context (age, sex, medications, smoking, family history). One abnormal value doesn’t equal disease — trends over time matter. Many values are modifiable with diet, exercise, weight loss, smoking cessation, blood pressure and lipid‑lowering drugs, glucose control, vitamin repletion, and targeted therapies (e.g., PCSK9/ statins for high ApoB/Lp(a considerations). Where to get tested (brands/services) Quest Diagnostics and Labcorp — national clinical labs; good for full panels and physician ordering. OmegaQuant — specialty lab for the RBC omega‑3 index (widely used in studies). Cleveland HeartLab or BostonHeart Diagnostics — for advanced cardiovascular biomarkers (Lp(a), ApoB, advanced inflammation panels). TruDiagnostic — for epigenetic age (DNA methylation clocks) if you’re curious about biological‑age testing. InsideTracker and WellnessFX — consumer‑facing services that bundle labs with interpretation and lifestyle guidance (helpful if you want actionable recommendations alongside results). Everlywell and LetsGetChecked — convenient at‑home kits for many routine tests (glucose, lipids, vitamin D, HbA1c, etc.), though not as comprehensive as a physician‑ordered panel. Practical recommendations Start with a baseline panel (lipid panel + ApoB or non‑HDL, HbA1c, CMP, CBC, hs‑CRP, vitamin D, Lp(a) once). Repeat annually or as directed by your clinician; more frequently if abnormal or if you’re changing therapy. Prioritize interventions shown to improve longevity: smoking cessation, blood‑pressure control, lipid lowering (statins/PCSK9 when indicated), weight management, physical activity, Mediterranean‑style diet, and good glycemic control. Use biomarkers to track response. Discuss abnormal or borderline results with a clinician before starting supplements or medications. Some advanced tests are useful in specialty care but add cost and complexity. Caveats Many biomarkers predict risk (association) but are not proven causal targets for longevity in all cases. Clinical decisions should balance biomarker data with symptoms, family history, and overall risk profile. Lab reference ranges vary by lab and by age/sex. Trends and the overall pattern matter more than single isolated values. If you want, tell me your age, sex, known medical conditions, and whether you want a minimal “high‑value” starter panel or a deeper advanced panel — I can propose a specific set of tests and suggest testing services to order them from.

Short answer: it depends a lot on what you mean by “full.” Prices range from about $20–$200 for basic bloodwork up to $300–$1,000+ for very comprehensive panels, and $2,000–$10,000 for advanced proteomics/genomics or executive physicals. More detail and concrete options 1) Basic clinical panels (CBC, CMP/metabolic panel, lipid panel, HbA1c, TSH) Typical cash cost: $20–$150. Where: Quest Diagnostics or Labcorp (widely available; insurance often covers when ordered by a clinician). Why choose: cheap, commonly used, and usually a good first step for overall health screening. 2) Expanded “wellness” panels (adds vitamin D, B12, ferritin, CRP, insulin, extra hormones) Typical cost: $100–$400. Where: Direct-to-consumer services like InsideTracker, WellnessFX, Everlywell, LetsGetChecked. Why choose: convenient, includes interpretation and personalized recommendations (InsideTracker and WellnessFX emphasize science-backed recommendations). 3) Micronutrients, fatty acids, and specialty nutrition tests Typical cost: $200–$500. Where: SpectraCell (micronutrient testing), OmegaQuant (fatty acids). Why choose: useful when you suspect deficiencies not captured by standard labs. 4) Advanced cardiovascular and hormone testing (NMR lipoprotein profile, ApoB, advanced inflammatory markers, full sex-steroid panels) Typical cost: $150–$600. Where: Labcorp/Quest for many advanced tests; DUTCH Test (Precision Analytical) for comprehensive hormone metabolites. Why choose: if you need finer cardiovascular risk stratification or detailed hormone metabolism info. 5) Proteomics / large biomarker discovery / multi-omics Typical cost: $2,000–$10,000+. Where: SomaLogic (SomaScan), Olink, research/clinical specialty labs. Why choose: research-grade, not generally needed for routine health management. 6) Executive/annual physical packages Typical cost: $500–$3,000+, varies by clinic and included tests/imaging. Where: private clinics, concierge medicine providers. Why choose: includes imaging, specialist consults and a broad battery of tests. Practical tips Insurance: many tests are covered when ordered by a clinician for a medical reason; direct-to-consumer kits typically aren’t covered. If cost is a concern, start with core labs (CBC, CMP, lipid, HbA1c, TSH, vitamin D) then add targeted tests based on those results and symptoms. Ask for lab test CPT codes and shop cash prices at Quest/Labcorp or use online price-comparison tools. If you tell me what you want to screen for (general wellness, hormones, cardiovascular risk, nutrient deficiencies, or a specific symptom), I can recommend a specific package and give a tighter price estimate.
