Good plan — annual blood testing is a useful part of preventive care. Below is a practical, tiered list: core tests most adults should consider every year, then additional tests to add depending on age, sex and risk factors. I also list where to get them and some practical tips. This isn’t a diagnosis — please review results with your primary care clinician to interpret findings and set follow-up.
Core annual panel (good baseline for most adults)
- Complete blood count (CBC) — checks for anemia, infection, platelet problems.
- Comprehensive metabolic panel (CMP) — kidney function (creatinine/BUN), liver enzymes (AST/ALT), electrolytes, glucose, albumin — basic organ/metabolic status.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — cardiovascular risk. Fasting not always required but some clinicians prefer fasting for TG/LDL accuracy.
- Hemoglobin A1c — screening for prediabetes/diabetes (or fasting glucose).
- Thyroid-stimulating hormone (TSH) — screens for hypothyroidism/hyperthyroidism.
- 25-hydroxy Vitamin D — many people are low; affects bone and immune health.
- Vitamin B12 — especially if age >50, on metformin, vegan/vegetarian, or symptomatic (numbness, fatigue).
- High-sensitivity C-reactive protein (hs-CRP) — optional; helpful for cardiovascular risk assessment when used with other risk factors.
Additional tests to consider by sex/age/risk
- Ferritin and iron studies — if heavy menstrual bleeding, suspected iron-deficiency anemia, fatigue.
- Prostate-specific antigen (PSA) — men: discuss with clinician starting around ages 45–50 (earlier with family history); decision-based screening.
- Sexually transmitted infection serologies (HIV, hepatitis B & C, syphilis) — at least once in adulthood and repeated annually if you have ongoing risk factors.
- Vitamin/mineral panels (magnesium, folate, calcium) — if clinical indication or restrictive diet.
- B-type natriuretic peptide (BNP) — if heart failure symptoms.
- Coagulation tests (PT/INR, aPTT) — if on anticoagulants or bleeding history.
- Urine albumin-to-creatinine ratio (not a blood test but often done with labs) — kidney damage screening in diabetes or hypertension.
- Advanced lipid tests (apoB, LDL particle number) — if strong family history of premature heart disease or unexplained high risk.
- Autoimmune or hormonal panels (e.g., estradiol, testosterone, cortisol, ANA) — only if symptoms suggestive or clinician-guided.
Frequency notes
- “Core” tests: typically once a year if stable. More often if abnormal results or new symptoms.
- Some tests (hepatitis C, HIV) may be once unless ongoing risk exposure — follow public health guidelines and your clinician’s advice.
Where to get tested (brands/services)
- Quest Diagnostics and LabCorp — largest national lab networks, accepted by most physicians and insurers; good for ordering through your doctor or self-pay.
- Your local hospital or community clinic lab — convenient if you want results in your electronic health record and clinician follow-up.
- Direct-to-consumer / at-home options: Everlywell and LetsGetChecked — convenient for some screening tests and deliver results online; good for people without easy access to a clinic, but follow-up with a clinician is still recommended. HealthLabs and Walk-In Lab/Any Lab Test Now also offer self-pay testing with broad menus.
- If you have insurance, ask your primary care clinic which lab they prefer to optimize coverage and result integration.
Practical tips
- Bring a printout or electronic copy of prior lab results for trend comparison.
- Ask whether fasting is required (lipid panel and some metabolic tests often need 8–12 hours fasting).
- Don’t order specialty tests (hormones, autoimmune, genetic) without discussing indications — these are often misused and can lead to confusing results.
- Review abnormal results with your clinician before starting treatments or supplements (e.g., vitamin D or iron dosing).
If you want, tell me your age, sex, medical history, medications (e.g., on blood thinners, diabetes meds, hormone therapy) and family-history specifics, and I’ll give a tailored list of annual tests and suggested timing.
