Good plan — a regular set of blood tests is a very effective way to track your overall health and catch problems early. Exact tests depend on your age, sex, family history, medications, and symptoms, but below is a practical annual checklist many clinicians use, why each test matters, and a few options for where to get them.
Core annual blood tests (good for most adults)
- Complete blood count (CBC): checks for anemia, infection, and some blood disorders.
- Comprehensive metabolic panel (CMP) or Basic metabolic panel (BMP): assesses kidney and liver function, electrolytes, blood glucose (in CMP) and overall metabolic status.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides): cardiovascular risk assessment; usually fasting unless your clinician advises otherwise.
- Hemoglobin A1c (or fasting glucose): detects diabetes or prediabetes and monitors glucose control.
- Thyroid-stimulating hormone (TSH) ± free T4: screens for hypo- or hyperthyroidism (common and often subtle).
- 25‑hydroxy Vitamin D: low levels are common and affect bone, immune and general health.
- Ferritin (and/or iron studies): screens for iron deficiency or overload; especially important if you have fatigue, heavy menstrual bleeding, or are vegetarian/vegan.
- High-sensitivity C-reactive protein (hs‑CRP): a non-specific marker of inflammation that helps refine cardiovascular risk in some people.
Additional tests to consider (based on age, sex, history or symptoms)
- PSA (prostate‑specific antigen): discuss with a clinician — often considered in men starting around 45–50 or earlier with family risk.
- Vitamin B12 (and folate) — older adults, vegetarians/vegans, or neurologic symptoms.
- Hepatitis C antibody, HIV, and other STI screens — at least once for adults (HCV screening recommended for most adults) or more often if risk factors.
- Hepatitis B surface antigen/antibodies — if not vaccinated or at risk.
- Ferritin / iron panel repeated more often if prior abnormal.
- Testosterone — if men have decreased libido, fatigue or other suggestive symptoms.
- Autoimmune or specialty markers (e.g., ANA, rheumatoid factor, thyroid antibodies) — only if symptoms or family history suggest autoimmune disease.
- BNP, troponin, or other cardiac markers — only for specific symptoms or heart disease monitoring.
- Medication monitoring labs (INR for warfarin, drug levels for some meds) as required.
How often
- Core tests annually is reasonable for general surveillance. Some (A1c, lipids, TSH) might be spaced differently if results are normal and you’re low risk (your clinician may recommend every 2–3 years). Tests for chronic conditions are done more frequently as needed.
Practical notes
- Many tests require fasting (lipid panel, fasting glucose): typically 8–12 hours. Ask when you book the draw.
- Always review abnormal results with your primary care clinician — they interpret results in context and decide next steps.
- If you have a chronic disease (diabetes, kidney disease, rheumatoid arthritis, etc.), you’ll need a disease-specific panel and frequency.
Where to get the tests (brands/services)
- Through your primary care physician or local hospital laboratory — best for integrated care and insurance coverage.
- National lab chains: LabCorp and Quest Diagnostics — broad test menus, lots of locations, and insurance-friendly.
- Physician-ordered online lab services: Pixel by LabCorp, HealthLabs or DirectLabs — let you order common panels without a clinic visit in many states.
- At‑home/direct‑to‑consumer kits: LetsGetChecked and Everlywell — convenient for some screening tests (sexual health, hormones, basic panels), but consider confirmatory testing through a clinical lab and share results with your clinician.
If you’d like, tell me your age, sex, any chronic conditions, medications, family history, or major symptoms and I’ll tailor a recommended annual test list and suggest which of the above services is best for you.
