Good question — an annual blood-work “checkup” is a smart way to catch problems early and track trends. The exact panel depends on your age, sex, medical history, meds and risk factors, but the list below covers the tests most clinicians use to get a broad, actionable picture of health. I’ll also name a few lab providers and at‑home services you can use.
Core annual blood tests (for most adults)
- Complete Blood Count (CBC) — evaluates red/white blood cells and platelets; detects anemia, infection, many blood disorders.
- Comprehensive Metabolic Panel (CMP) — includes electrolytes, kidney function (creatinine/eGFR), and liver enzymes (AST/ALT, bilirubin); checks metabolic health and organ function.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — cardiovascular risk assessment; guides preventive therapy.
- Hemoglobin A1c (or fasting glucose) — screens for prediabetes/diabetes; A1c gives 2–3 month average blood sugar.
- Thyroid-stimulating hormone (TSH) — screens for hypothyroidism/hyperthyroidism; add free T4 if abnormal or symptomatic.
- 25‑hydroxy Vitamin D — common deficiency with wide effects (bones, mood, immunity).
- High-sensitivity C‑reactive protein (hs‑CRP) — inflammation marker useful for cardiovascular risk stratification.
- Urinalysis (not blood, but useful) — screens for kidney disease, diabetes effects, urinary infections.
Important additional tests to consider (based on age, sex, family history, symptoms, or medication)
- Ferritin and iron studies — if you have fatigue, suspected anemia, heavy periods, or iron overload risk.
- Vitamin B12 — especially if you’re older, vegan/vegetarian, or on metformin/PPIs.
- Hepatitis B and C screening — if you have risk factors or were born in certain years/countries (Hep C recommended once for baby boomers and at-risk groups).
- HIV and syphilis (RPR) — sexually active people with risk factors.
- Prostate-specific antigen (PSA) — men: discuss with your clinician; usually considered from ~50 years (earlier if high risk).
- Testosterone (total and free) — men with symptoms of low libido, fatigue, muscle loss.
- Lipoprotein(a) and ApoB — one-time or periodic tests if family history of premature heart disease or to refine cardiovascular risk.
- ANA, rheumatoid factor, ESR — if you have symptoms of autoimmune disease.
- Coagulation panel (PT/INR, aPTT) — only if bleeding/clotting risk or on anticoagulants.
- Pregnancy test (if applicable) and relevant hormone panels for fertility concerns.
Frequency guidance
- Baseline “full” set: annually for most adults.
- More often (every 3–6 months) if you have a chronic condition, abnormal result, are on medication requiring monitoring (statins, anticoagulants, diabetes meds), or recently started a new therapy.
- Some tests (Lp[a]) may be done once since they’re genetically determined.
Where to get testing (brands/services)
- Quest Diagnostics and LabCorp — large national networks, accept most insurance, good for physician-ordered or self-referred testing.
- Your primary care clinic or hospital lab — sensible if you want your clinician to receive and act on results directly.
- At‑home/direct‑to‑consumer options (convenient for screening; check what’s included): Everlywell, LetsGetChecked, HealthLabs, and InsideTracker (InsideTracker provides deeper biomarker interpretation and personalized recommendations). These often include physician review for abnormal results but may not be covered by insurance.
- If cost or privacy is a concern, compare prices on sites like HealthLabs or local lab vouchers.
Practical tips
- Bring a copy of prior results or use the same lab when possible to track trends.
- Some tests require fasting (lipid panel, fasting glucose); A1c does not. Ask beforehand.
- Discuss abnormal or borderline results with your clinician — decisions (medication, lifestyle, further testing) are individualized.
- Share family history (early heart disease, cancers) so your clinician can recommend age‑ and risk‑specific tests (genetic testing, imaging, earlier screening).
If you want, tell me your age, sex, major health issues, medications, and any family history of chronic disease (early heart disease, diabetes, cancer) and I’ll give a tailored annual labs checklist and suggest which tests you might prioritize.
