Good question — getting a consistent set of annual blood tests is one of the best ways to track overall health and catch problems early. Below is a practical, evidence‑based checklist you can discuss with your primary care clinician. I also note which tests are routine vs. risk- or age‑based, give a short reason for each, and recommend places to have them done.
Core annual blood tests (good for most adults)
- Complete Blood Count (CBC) — screens for anemia, infection, and some blood disorders.
- Comprehensive Metabolic Panel (CMP) — includes electrolytes, kidney function (creatinine, eGFR), and liver enzymes (ALT/AST) to assess metabolic and organ health.
- Lipid panel (total cholesterol, LDL, HDL, triglycerides) — cardiovascular risk assessment. Consider fasting if ordered that way.
- Hemoglobin A1c (or fasting glucose) — screens for diabetes/pre‑diabetes (A1c reflects average glucose over months).
- Thyroid Stimulating Hormone (TSH) — screens for underactive or overactive thyroid; add free T4 if abnormal or if symptoms.
- 25‑hydroxy Vitamin D — many people are low; affects bone, immune and other functions.
- Vitamin B12 — useful especially if older, vegetarian/vegan, on metformin or proton‑pump inhibitors.
- Ferritin (and iron studies if indicated) — assesses iron stores; useful if fatigued or women with heavy periods.
- High‑sensitivity C‑reactive protein (hs‑CRP) — nonspecific inflammation marker that helps cardiovascular risk stratification in some cases.
Age, sex, and risk‑based tests (consider these based on personal/family history)
- Prostate‑specific antigen (PSA) — discuss with your clinician if you’re a man around age 50 (earlier if family history or Black race).
- Lipoprotein(a) and apolipoprotein B (apoB) — one‑time or periodic testing if strong family history of early heart disease.
- Hepatitis C antibody — one‑time screening for many adults (CDC recommends one‑time testing for all adults born 1945–1965 and others at risk; guidelines have changed to expand screening).
- HIV, syphilis, and other STI testing — as indicated by sexual history/risk.
- Sex hormones (testosterone or estradiol) — if symptoms of low/high sex hormones or fertility concerns.
- Morning cortisol, ACTH stimulation, autoimmune markers (ANA, rheumatoid factor) — only if symptoms suggest endocrine or autoimmune disease.
- Fasting insulin or oral glucose tolerance test — when detailed assessment for insulin resistance is needed.
- Ferritin, folate, homocysteine — if specific symptoms or nutritional risk.
- Pregnancy test, rubella immunity, and reproductive hormone workups — for family‑planning or perinatal care.
Lifestyle and medication considerations
- If you take statins, metformin, or other chronic medications, your clinician may order liver tests, CK, or other monitoring more often.
- If you use anticoagulants (warfarin), you’ll need INR checks per your provider.
- Smokers, heavy drinkers, or people with occupational exposures may need additional testing (e.g., lung or liver assessments).
How to get the tests and recommended services
- LabCorp or Quest Diagnostics — large national labs; accept most physician orders and accept many insurances. Good for comprehensive panels and widely available.
- Your health system or hospital lab (e.g., Mayo Clinic, Cleveland Clinic, Kaiser Permanente labs) — convenient if you have a primary care provider there and can be preferred for continuity.
- Quest Direct or LabCorp Pixel, and direct‑to‑consumer services (Everlywell, LetsGetChecked) — order some tests without a clinician in certain states. Convenient, but they may not offer full diagnostic follow‑up; results should be reviewed with a clinician.
Why these: Quest/LabCorp/hospital labs offer clinical accuracy, broad test menus, and are usually covered by insurance; consumer services are convenient but limited for interpretation and follow‑up.
Practical tips
- Bring this checklist to your primary care provider so tests are ordered appropriately and covered by insurance when possible.
- Fast 8–12 hours before tests if your doctor orders a fasting lipid panel or fasting glucose. Clarify with your lab whether water is allowed (usually yes).
- Keep a record of results year‑to‑year (many labs offer patient portals). Trends matter more than single values.
- If a test is abnormal, follow up with your clinician before making medication or supplement changes.
If you’d like, tell me your age, sex, major medical history (diabetes, heart disease, family history), and whether you prefer an in‑person lab or an at‑home test — I can give a personalized annual panel and recommend which specific tests to prioritize.
