Great — here’s a practical, clinician-friendly checklist you can use as a baseline annual blood-work plan plus guidance on what to add depending on age, sex and risk factors. Always review results with your primary care clinician before making treatment changes.
Core annual blood tests (good for most adults)
- Complete metabolic panel (CMP) — includes glucose (if fasting), electrolytes, kidney function (creatinine, eGFR), liver enzymes (AST/ALT), bilirubin, albumin. Why: gives an overall look at metabolism, liver and kidney health. Fasting usually preferred for the glucose value.
- Complete blood count (CBC) — red/white cells, hemoglobin, hematocrit, platelets. Why: screens for anemia, infection, some blood disorders.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — Why: cardiovascular risk. Fasting is often recommended (or nonfasting is acceptable per many guidelines, but fasting gives more consistent triglycerides).
- Hemoglobin A1c (HbA1c) — Why: average blood sugar over ~3 months; screens for prediabetes/diabetes.
- Thyroid-stimulating hormone (TSH) — Why: screens for hypothyroidism/hyperthyroidism (add free T4 if abnormal or if symptoms).
- 25‑hydroxy Vitamin D — Why: deficiency is common and affects bone, immune, and muscle health.
- Basic inflammation marker — high-sensitivity C‑reactive protein (hs‑CRP) — Why: adjunct for cardiovascular risk in some people (not diagnostic).
- Urinalysis (dip/urine microscopy) — Why: screens for kidney issues, blood, infection — often done annually.
Additional tests to consider based on sex, age, history, or risks
- Ferritin and iron studies — especially for premenopausal women, anyone with anemia symptoms, or suspected iron deficiency.
- Vitamin B12 — older adults, vegetarians/vegans, or people on metformin or proton-pump inhibitors.
- HIV, hepatitis B and C screening — based on risk factors; CDC recommends at least once for everyone 13–64 and more often if high risk.
- Sexually transmitted infection testing (e.g., chlamydia, gonorrhea, syphilis) — based on sexual activity/risk.
- Advanced lipid markers (ApoB, Lp(a)) — if family history of early heart disease or unclear risk after standard lipid panel.
- Prostate-specific antigen (PSA) — men: shared decision-making generally begins around ages 50 (45 if higher risk such as African ancestry or family history). Not routine for all younger men.
- Testosterone — if men have symptoms of low libido, fatigue, or other hypogonadism signs.
- Estradiol, FSH/LH — for women with menopausal symptoms or infertility concerns.
- Antibody/autoimmune panels (e.g., anti‑TPO) — if you have symptoms of autoimmune thyroid disease or other autoimmune symptoms.
- NT‑proBNP or troponin — only if there are symptoms or known heart disease (not routine screening).
- Cancer tumor markers (CA‑125, CEA, PSA beyond age-based guidance) — generally NOT recommended for routine screening in asymptomatic people; use selectively under medical advice.
How to choose which tests annually
- Baseline core set above for most adults.
- Add tests tailored to: age (e.g., PSA, B12, bone markers), sex (ferritin for menstruating women, reproductive hormones for women trying to conceive), family history (lipoprotein(a), earlier lipid screening), medications (metformin → B12), and risk behaviors (HIV/hepatitis/STI testing).
- If you have chronic conditions (diabetes, kidney disease, liver disease, anticoagulation), get disease-specific monitoring as recommended by your clinician (may be more frequent).
Where to get tests (brands/services)
- Through your PCP or health system lab — usually ordered by your clinician; results go into your medical record (recommended).
- Large national labs: Quest Diagnostics, LabCorp — widely accepted, many locations, insurance-friendly.
- Direct-to-consumer (DTC) options if you don’t have a PCP appointment: Everlywell, LetsGetChecked, HealthLabs/DirectLabs, and Walk-In Lab — they offer common panels and ship or direct you to local draw sites. Good for convenience but avoid making treatment decisions without clinician review.
- For performance/optimization services (more interpretation/coaching): InsideTracker, WellnessFX — useful if you want lifestyle-focused interpretation, but costly. Note: Costs and insurance coverage vary; using your PCP and in-network labs often lowers out-of-pocket expense.
Practical tips
- Fast 8–12 hours for tests that require fasting (standard lipid panels and some glucose tests). Check instructions from the lab.
- Bring results to a primary care visit to interpret trends (single values matter less than changes over time).
- Don’t over-screen with specialty tumor markers or broad autoimmune panels unless symptoms or a clinician recommends them — overtesting can cause false positives and unnecessary follow-up.
- Keep a copy of your lab results in case you switch doctors.
When to talk to your doctor immediately
- New dizziness, shortness of breath, chest pain, sudden weakness, unusual bleeding, very high fever, or severe fatigue — ask for immediate evaluation and targeted labs or imaging.
