From the UK Society of Medical Longevity
The longevity toolkit
Practical metabolic testing for everyday practice.
Most patients walking into your clinic have already been told their bloods are normal. The reference range is not a standard of health. It is a population average drawn from a population that is largely unwell, and a patient can sit comfortably inside every range while accumulating risk for two decades.
This toolkit grades every test named in our CCR London session two ways: by the strength of its evidence, and by how you actually get hold of it in the UK. It then sets out a twelve month structure you can run from Monday morning, inside an NHS or private practice, with no new equipment.

How this document is built
Two questions, not one.
Most longevity testing lists collapse two separate questions into a single recommendation. We keep them apart, because a test can be strongly evidenced and still be difficult to obtain, and a test can be easy to order and carry almost no evidence at all.
A grade is not a recommendation to order. It is a statement about what you are entitled to conclude once you have.
The first question
How good is the evidence?
Supported
Consistent evidence from well conducted trials, or from large and repeatedly replicated cohorts. Reasonable to act on.
Informed
Reasonable evidence, but incomplete or indirect. Useful for building a picture, not for a single decision on its own.
Emerging
An early signal worth watching. Not yet a basis for practice, and not something to charge a patient for as though it were settled.
Not endorsed
The society declines to support this claim on the current evidence.
The second question
How do you actually get it?
NHS routine
Already on the panels you order, or already commissioned in primary care. No new spend.
NHS on request
Available through NHS laboratories or pathways, but not included by default. You have to ask for it by name.
Private
Not routinely available on the NHS for this indication. Patient funded, or through a private provider.
Inside the toolkit
Thirteen pages, three tiers, one structure.
Tier one
What is already on the page. HbA1c read positionally, GGT, ferritin in both directions, the FBC differential, eGFR as a trajectory, urine ACR. Plus the indices you own already: triglyceride to HDL, TyG, neutrophil to lymphocyte ratio, FIB-4. And the measures that need no laboratory at all.
Tier two
Strong evidence, outside routine practice. High sensitivity CRP and AST, both of which have to be requested by name. Lipoprotein(a), apolipoprotein B, VO2 max, coronary artery calcium, cystatin C, the ELF test, and where hormone assessment does and does not help.
Tier three
Advanced longevity and functional testing, graded honestly. Epigenetic clocks, glycan age, microbiome panels, multi-cancer detection and whole body imaging, each placed where the current evidence puts it rather than where the marketing does.
And then what
Five visits. Twelve months.
The structure
Five visits across twelve months, with what happens at each one, and a plain statement of what moves and roughly when. Symptoms in weeks. Triglycerides, hs-CRP and waist by three months. HbA1c, GGT and grip strength by six. Organ trajectory and risk score by twelve.
Move, eat, recover
The three inputs, the four nutrients with clinical data worth defending, and a page on women specifically, because every twelve month programme quietly assumes a patient has the sleep, mood and energy to execute it.

The inaugural scientific meeting
Longevity medicine will only become a recognised clinical discipline in the UK if somebody is willing to grade the evidence honestly, including when the answer is inconvenient. That is what this society exists to do, and our inaugural meeting is where it starts.
One day covering the science of ageing, metabolic health, precision diagnostics and how to interpret data without over-testing, women's health and hormonal transitions, and how to build a longevity clinic within UK clinical governance. Places are for GMC-registered doctors.
