Good plan — getting a yearly set of blood tests gives a solid baseline and helps catch trends early. Exact tests should be personalized by age, sex, family history, medications, and symptoms, so take this list to your primary care clinician or a trusted telehealth provider. Below I list a practical “core” annual panel, additional tests to consider by risk/age, brief timing notes (fasting, morning), and where/how to get them (brands/services).
Core annual tests (recommended for most adults)
- Complete blood count (CBC) — screens for anemia, infection, platelets.
- Comprehensive metabolic panel (CMP) — includes kidney function (creatinine, BUN), electrolytes, liver enzymes (AST/ALT), albumin, total protein, and glucose.
- Lipid panel — total cholesterol, LDL, HDL, triglycerides (fasting recommended for some people).
- Hemoglobin A1c (A1c) — average blood glucose over 2–3 months; screens for diabetes/prediabetes.
- Thyroid-stimulating hormone (TSH) — basic screen for hypothyroidism/hyperthyroidism; add free T4 if abnormal or symptomatic.
- 25‑hydroxy vitamin D — common deficiency that affects bones/immune health.
- Vitamin B12 — especially if older, vegetarian/vegan, or on metformin/PPI.
- High-sensitivity C‑reactive protein (hs-CRP) — general inflammation and cardiovascular risk marker.
- Ferritin (iron stores) — helps evaluate iron deficiency or overload (especially if fatigue or heavy menses).
Additional tests to consider depending on age, sex, risk factors, symptoms
- Prostate-specific antigen (PSA) — discuss with your clinician if male and age ≥45–50 or higher risk.
- Total testosterone (morning) — if male with decreased libido/energy or muscle loss; consider free testosterone if needed.
- Estradiol, FSH/LH — if evaluating menstrual/menopausal symptoms.
- Iron studies (TIBC, transferrin saturation) — if anemia or hereditary hemochromatosis risk.
- Hepatitis B and C screening — one-time screening for many adults (CDC recommends hepatitis C screening at least once for all adults 18–79), repeat if risk factors.
- HIV and other STI screening — at least once and repeated based on risk/behaviors.
- Lipoprotein(a) and apolipoprotein B (ApoB) — if strong family history of early heart disease.
- Homocysteine — sometimes used in cardiovascular risk or B-vitamin assessment.
- Insulin or fasting glucose/insulin — if metabolic syndrome, obesity, or family history of diabetes.
- Kidney microalbumin/creatinine ratio — if diabetic or hypertensive (often urine test).
- Coagulation tests (PT/INR, aPTT) — if on anticoagulants or bleeding history.
How often and timing
- Most items above: yearly if normal; more often if abnormal or high risk.
- A1c: at least yearly if prediabetes/diabetes; more frequently if treatment changes.
- Lipids: every 4–6 years if low risk and normal; yearly if on therapy or high risk.
- Fasting required for some lipid panels and fasting glucose/insulin — check lab instructions (usually 8–12 hours).
- Morning draw recommended for testosterone testing.
How to get the tests (services/labs)
- Through your PCP / health system — often covered by insurance and gives results with interpretation.
- Quest Diagnostics or LabCorp — nationwide clinical labs that accept physician orders and many insurance plans.
- Direct-access labs / consumer testing (good if you don’t have a PCP order): HealthLabs (healthlabs.com), Ulta Lab Tests (ultalabtests.com), or Any Lab Test Now. These can be cost-effective but may charge out-of-pocket and vary in physician result reviews.
- Home/consumer kits for select tests: Everlywell and LetsGetChecked offer at-home sample collection for A1c, vitamin D, lipids, and STIs. Useful for convenience but more limited panels and interpretation.
- Personalized tracking/coaching services: InsideTracker and WellnessFX (partnerships may vary) provide expanded biomarker panels plus interpretation, lifestyle recommendations, and trend tracking — good if you want in-depth interpretation and actionable coaching.
- Telehealth primary-care services (One Medical, Carbon Health, Forward) — can order annual labs and combine them with a televisit for interpretation.
Practical notes
- Bring previous results so trends can be followed — trends matter more than single values.
- Tell the lab about medications and supplements (biotin can interfere with some tests).
- Discuss which tests your insurer covers vs. out-of-pocket costs for direct-to-consumer services.
- Some screens (e.g., hepatitis C, HIV) are one-time for most people but should be repeated with ongoing risk.
If you want, tell me your age, sex, family history, current meds (especially statins, metformin, supplements like biotin), and any symptoms. I’ll tailor a recommended annual panel and say which tests you could skip or should add.
