The short answer: book a broad baseline in January that covers heart (cholesterol and ApoB), blood sugar (HbA1c), liver, kidney, thyroid, iron, vitamin D, B12 and inflammation, then retest about three months later to see what your changes did. If you are 40 to 74, live in England and haven't had one, the free NHS Health Check is the place to start; it covers cholesterol, blood pressure and heart risk, not a full panel.
The most useful blood test is the second one. A January result tells you where you are; a retest after about three months shows what the changes you made actually did, in numbers rather than how you feel.
Three months is not arbitrary. HbA1c reflects your average blood sugar over the previous two to three months, because that is roughly how long red blood cells last (Diabetes UK). A retest in April therefore reflects your January to March, not your Christmas.
Two cautions. Vitamin D is usually at its lowest in winter, so compare next January with this January rather than with a summer result. And a single result is a snapshot: anything unexpected is a reason to repeat it or speak to your GP, not to act on one number. How often should you get a blood test?

TrueVitals facts: Ultimate: 140 biomarkers (139 for women), £349 + £19 clinic draw or £39 home visit, venous sample, Nationwide Pathology (UKAS-accredited), clinician-reviewed report within 4 working days, 103 partner clinics.
Where TrueVitals fits: one draw that covers the whole checklist, including Lp(a), fasting insulin and cystatin C, with a written report that reads the results together and is compared with your next test. It is a newer brand than Medichecks or Forth.
At minimum: cholesterol (ideally with ApoB), HbA1c, liver and kidney function, a full blood count, thyroid function, ferritin and iron, vitamin D, B12 and folate, and an inflammation marker. Add hormones if you have symptoms or are in your 40s or 50s. The table on this page shows which UK panels include each.
Yes, in England. The NHS Health Check is free for adults aged 40 to 74 who do not already have heart disease, diabetes, kidney disease, high blood pressure, atrial fibrillation or a previous stroke, and you should be invited every 5 years. It checks your cholesterol, blood pressure and possibly blood sugar, and estimates your risk of heart disease and stroke. If you are eligible and have not had one, start there.
Because it gives you a baseline before any New Year changes, so a retest about three months later shows what those changes did. Three months is a natural interval: HbA1c reflects your average blood sugar over the previous two to three months (Diabetes UK). One caution: vitamin D is usually at its lowest in winter, so compare January results with a later January, not with summer.
Pay online for the panel, then book by phone: either a clinic draw at one of 103 partner clinics (£19) or a home visit (£39). Booking is by phone after payment rather than online. Your sample goes to Nationwide Pathology (UKAS-accredited) and the clinician-reviewed report arrives within 4 working days.
For panels that include fasting insulin or fasting glucose, yes: usually an overnight fast with only water, and a morning draw. Take your usual medicines unless your doctor has told you otherwise. Each provider gives its own preparation instructions; see our fasting guide.
