Annual Blood Test Checklist: The Minimum Every Adult Should Get
Most adults get far too few blood tests each year — or none at all. This is the evidence-based minimum panel that every adult should receive annually, why each test is included, and what to do with the results.

The most common serious health conditions — cardiovascular disease, type 2 diabetes, kidney disease, liver disease, thyroid dysfunction, anaemia — develop silently over years. By the time symptoms appear, significant damage has occurred. Annual blood testing catches these conditions during the window when intervention is most effective. It also establishes a personal baseline: your trend over time is more informative than a single snapshot against a population reference range.
The Core Annual Panel — What to Always Include
Every annual check should include at minimum: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP) — glucose, kidney, liver, electrolytes, fasting lipid panel with LDL/HDL/triglycerides, HbA1c, TSH (thyroid), and vitamin D (25-OH). These seven panels cover the six health domains — metabolic, cardiovascular, kidney, liver, blood, and inflammatory — and take one blood draw.
| Test | What It Screens For | Who Needs It |
|---|---|---|
| Full blood count (CBC) | Anaemia, infection, platelet disorders, blood cell abnormalities | Everyone annually |
| Comprehensive metabolic panel (CMP) | Blood glucose, kidney function (creatinine/BUN), liver enzymes, electrolytes, albumin | Everyone annually |
| Fasting lipid panel | LDL, HDL, triglycerides, total cholesterol | Everyone every 1–5 years depending on risk; annually if on lipid-lowering therapy |
| HbA1c | Average blood glucose over 3 months — screens for prediabetes and diabetes | Everyone over 35; younger adults with risk factors |
| TSH | Thyroid function — hypo and hyperthyroidism | Everyone every 1–3 years; annually in women over 50 |
| Ferritin | Iron stores — often depleted before CBC shows anaemia | All premenopausal women; men with symptoms; vegetarians/vegans |
| 25-OH Vitamin D | Vitamin D status — deficient in 42% of US adults | Everyone annually |
| eGFR + uACR | Kidney filtration rate and early kidney damage marker | Everyone with diabetes, hypertension, or over 60 |
Getting the Most From Annual Testing
Timing matters: most fasting blood tests (glucose, lipids, iron studies) should be done after 8–12 hours of fasting. Testosterone testing requires a morning draw (7–10 AM) to capture the peak. CK should be drawn at least 24 hours after exercise. Getting tested at the same time each year, under the same conditions (similar fasting duration, similar activity level in the preceding days), maximises the value of year-over-year comparisons.
Add-Ons Worth Requesting With Your Annual Panel
Interpreting Your Results: Trends Trump Single Readings
A single blood test result is a snapshot. A trend is a story. An LDL of 120 mg/dL is meaningless without context — but LDL rising from 95 to 105 to 120 over three years is an actionable signal worth investigating. Keeping your own record of annual results in a simple spreadsheet enables trend monitoring that most healthcare systems fail to provide proactively.
