Good question — an annual set of blood tests can give a useful “baseline” and catch many common problems early. The exact list should be tailored to your age, sex, family history, medications (e.g., metformin, statins, hormone therapy), and risk factors, but here’s a practical general panel and why each test matters.
Core annual blood tests
- Complete blood count (CBC) — looks for anemia, infection, and basic blood disorders.
- Comprehensive metabolic panel (CMP) or Basic metabolic panel (BMP) — measures kidney function (creatinine, eGFR), electrolytes, blood glucose (sometimes), and liver enzymes. Useful for medication safety and organ function.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — cardiovascular risk assessment and to monitor statins if you take them. Fasting vs non‑fasting depends on the lab/clinician.
- Hemoglobin A1c (or fasting glucose) — screens for prediabetes/diabetes and monitors control if you have diabetes. A1c is convenient and not fasting.
- Thyroid stimulating hormone (TSH) ± free T4 — screens for hypothyroidism or hyperthyroidism (common with aging).
- 25‑hydroxy Vitamin D — many adults are low; deficiency affects bones, immunity and energy.
- High‑sensitivity CRP (hs‑CRP) — optional: a marker of systemic inflammation and added cardiovascular risk info in some people.
- Ferritin/iron studies — especially for menstruating people, those with fatigue, or suspected iron deficiency.
- Vitamin B12 — if you’re older, on metformin, vegan/vegetarian, or have neurologic symptoms.
Other tests to consider (based on risk)
- Prostate specific antigen (PSA) — men should discuss PSA testing with their clinician (often starts ~45–50 depending on risk).
- Hepatitis B/C and HIV — screen if you have risk factors, new sexual partners, past injection drug use, or born in high‑risk areas. Some guidelines endorse broader screening in adults.
- Sexually transmitted infection panels (chlamydia, gonorrhea, syphilis) — if sexually active with risk.
- Testosterone (total/free) — if you have low libido, erectile dysfunction, or other symptoms (men).
- Autoimmune or additional endocrine tests — only if symptoms suggestive.
- Urinalysis (not blood but useful) — yearly for kidney/bladder screening in some people.
Frequency notes
- Many of these are reasonable yearly for adults with risk factors or on chronic meds. For low‑risk younger adults, some (like A1c, vitamin D, B12) can be checked less often (every 2–3 years) unless abnormal or symptomatic. Discuss personalized intervals with your clinician.
Where to get tests (brands/services)
- Quest Diagnostics or LabCorp — large nationwide networks; accept physician orders and many insurances; good for full clinical panels and specialists.
- Your primary care clinic or health system labs — best when you want a clinician to order, interpret, and act on results. Many insurers cover testing when ordered by your PCP.
- Everlywell or LetsGetChecked — convenient at‑home kits for common wellness tests (lipids, A1c, thyroid, vitamin D). Good for convenience, but less oversight for abnormal results (LetsGetChecked includes nurse follow‑up).
- HealthLabs.com or DirectLabs — direct‑to‑consumer lab orders at transparent prices if you don’t want a doctor’s order; still best to review results with a clinician.
- One Medical or other concierge primary care — coordinate annual screening and follow‑up if you prefer a membership model.
Important: abnormal results should be interpreted in context — bring results to your primary care clinician before making decisions.
If you want, tell me your age, sex, current medications, major health problems, and any family history (heart disease, diabetes, thyroid disease, cancers) and I’ll give a tailored annual testing checklist.
