Good plan — annual blood testing is a great way to catch problems early. Which exact tests you need depends on your age, sex, family history, medications and risk factors (smoking, obesity, diabetes, heart disease). Below is a practical, clinician-oriented “annual baseline” list plus some add-ons to consider. I’ll also recommend labs/services you can use.
Core annual blood tests (good for most adults)
- CBC (complete blood count) — screens for anemia, infection, some blood disorders.
- CMP (comprehensive metabolic panel) — includes glucose, electrolytes, kidney function (creatinine, eGFR) and basic liver tests (AST/ALT, bilirubin). Gives broad organ-function snapshot.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — cardiovascular risk. Fasting often preferred but many labs accept non‑fasting results.
- HbA1c (or fasting glucose) — screening for prediabetes/diabetes and average blood sugar control.
- TSH (thyroid-stimulating hormone) — primary screen for hypothyroidism/hyperthyroidism. Add free T4 if abnormal or symptomatic.
- Vitamin D (25‑OH vitamin D) — common deficiency that affects bone and possibly other health outcomes.
- Vitamin B12 — important for energy, neurologic function; low is common in older adults and people on metformin or acid-suppressing meds.
- Ferritin (iron stores) — especially important for premenopausal women, those with heavy periods, or unexplained fatigue.
Useful/additional tests based on risk or age
- hs‑CRP (high-sensitivity C‑reactive protein) — marker of systemic inflammation; can help refine cardiovascular risk in some patients.
- Urine albumin-to-creatinine ratio (UACR) — if diabetic or hypertensive, to screen for early kidney damage.
- Hepatitis C and HIV screening — at least once in adulthood; repeat annually if ongoing high‑risk behaviors. Hep B screening based on immunization and risk.
- Ferritin + total iron/TIBC — if anemia or iron deficiency suspected.
- B-type natriuretic peptide (BNP) — if heart failure symptoms are present.
- Testosterone (total ± free) — for men with low energy, low libido, or other symptoms.
- PSA (prostate-specific antigen) — shared decision-making for men starting around age 50 (earlier if high risk/family history).
- Folate, homocysteine, or other micronutrients — targeted when indicated.
- Lipoprotein(a) and/or ApoB — one-time or occasional measurements if strong family history of early heart disease.
- More specialized endocrine or autoimmune panels only if symptoms indicate.
How often (practical)
- Annual: CBC, CMP, lipid panel, HbA1c (or fasting glucose), TSH, vitamin D, B12, ferritin for most adults.
- More frequently (every 3–6 months) if you’re being treated for a condition or on meds that affect labs.
- One-time or periodic: Lp(a), ApoB, hepatitis/HIV depending on history.
Logistics and tips
- Fasting: 8–12 hours for traditional lipid panel and fasting glucose. Check lab instructions — many institutions accept nonfasting lipids for screening.
- Bring results to your primary care provider for interpretation and follow-up; trends over time matter more than a single value.
- Track results (apps, patient portal) and repeat abnormal tests sooner rather than waiting a year.
Where to get tests (brands/services)
- Labcorp and Quest Diagnostics — nationwide diagnostic labs with broad test menus; accept physician orders and most insurance. Good if your doctor orders tests.
- HealthLabs / DirectLabs — let you order many routine tests directly without a doctor’s visit in many states (costs vary).
- LetsGetChecked and Everlywell — at‑home collection kits for common panels (lipids, thyroid, vitamin D, STD testing). Convenient, include clinician review in many cases.
- InsideTracker — focuses on personalized interpretation and lifestyle recommendations (adds actionable coaching but more expensive).
Why these: Labcorp/Quest have wide test availability and insurance billing; LetsGetChecked/Everlywell are convenient for home collection; InsideTracker offers deeper interpretation and lifestyle guidance.
Final notes
- A “full picture” isn’t just blood tests: include blood pressure, weight/BMI, waist circumference, vaccination status, cancer screenings (Pap, mammogram, colonoscopy) and a medication/mental-health review.
- Discuss the panel and any abnormal findings with your primary care clinician — they’ll tailor testing to your personal risks and decide on follow-up.
If you tell me your age, sex, medical history, medications and major concerns (family history of heart disease, diabetes, early cancer, etc.), I can give a tailored annual test list and suggest whether any tests should be added or done more/less often.
