How Often Should You Get Blood Tests?
There is no single universal answer — testing frequency should match your age, risk factors, and what you are monitoring. This guide gives specific recommendations by age group, health condition, and what each test is monitoring for.

| Test | Healthy Adults (no major risk factors) | Higher Risk Adults |
|---|---|---|
| Full blood count (CBC) | Every 1–2 years | Annually (chronic disease, on medications) |
| Comprehensive metabolic panel | Every 1–3 years | Annually (hypertension, diabetes, kidney disease, on ACE inhibitors) |
| Fasting lipid panel | Every 4–6 years (US Preventive Services Task Force guideline) | Annually (known dyslipidaemia, on statins, family history CVD) |
| HbA1c | Every 3 years starting at 35 (ADA recommendation) | Every 3–6 months (type 2 diabetes); annually (prediabetes) |
| TSH | Every 3–5 years | Annually (women over 50, Hashimoto's, on levothyroxine) |
| Vitamin D | Annually (deficiency is common; supplements alter levels) | Every 6 months if correcting deficiency |
| Ferritin | Annually for premenopausal women; every 2–3 years for men | Every 6 months if treating iron deficiency |
If You Are Managing a Chronic Condition
Type 2 diabetes: HbA1c every 3 months until controlled, then every 6 months. Annual comprehensive metabolic panel, lipid panel, uACR (kidney screen), and CBC. Hypertension: Annual electrolytes and creatinine (especially if on ACE inhibitor/ARB or diuretics), annual lipid panel, uACR. CKD: Frequency escalates by stage — CKD stage 3 warrants biannual monitoring; CKD stage 4 warrants quarterly. On statins: Lipid panel 4–8 weeks after starting or changing dose; annually once stable. Liver enzymes if symptomatic (routine monitoring is no longer recommended by guidelines).

The Longevity Medicine Approach: More Frequent, More Comprehensive
A growing segment of health-optimisation medicine advocates annual comprehensive panels even in healthy adults — including ApoB, Lp(a), hs-CRP, homocysteine, fasting insulin, and a full micronutrient screen. The rationale is that establishing annual trends in healthy years provides a personalised baseline, and that many disease processes (atherosclerosis, insulin resistance, nutrient depletion) can be halted or reversed when caught early. Whether this level of testing adds clinical value beyond standard screening guidelines is an active debate — but it is increasingly accessible and affordable through DTC testing services.
