The original Meterbolic diagnostic
The KRAFT Test.
The insulin-response test behind the science — Dr Joseph Kraft's method, run outside the lab.
Insulin response · 3 hours
Illustrative
Two people can share the same fasting glucose number and have completely different curves. The shape — how high insulin climbs, and how long it stays there — is the signal.
What the test actually measures
A glucose challenge, measured properly
A standard fasting glucose test takes one snapshot on one morning. The KRAFT Test gives you a measured glucose load and then reads your insulin response across the hours that follow — the part almost nobody measures.
Insulin, not just glucose
Insulin rises to hold glucose down, so glucose can look normal for years while insulin is quietly working overtime. Reading the insulin curve is what surfaces that compensation while it is still reversible.
Your curve, against Kraft’s patterns
Dr Joseph Kraft ran insulin-response surveys on more than 14,000 people and grouped the results into distinct response patterns. Your curve is read against that framework and returned as a plain-English pattern, not a wall of numbers.
Clinical-grade analysis
Run on Meterbolic’s proprietary lateral-flow analyser, CE-IVD marked and manufactured in an FDA-approved facility. Results are reviewed before they reach you.
The two options
The test, or the test and a plan
Both are booked by appointment — there is no online checkout. Email us and we'll arrange a slot and confirm the right route for you.
The KRAFT Test
One-off test · by appointment

Prices in GBP. The KRAFT Test is not sold online — every booking is arranged by appointment with our team, who will confirm availability and the right route for you before anything is paid.
Where you take it
Both options above can be run either way. Which route is open to you depends on where you are — we'll confirm when you enquire.
Through a certified clinic
Your appointment is run by a practitioner in the Meterbolic network. They take the readings, we analyse the curve, and you get the report and a follow-up conversation.
As a home kit
The mail-in route for people who aren’t near a clinic. The kit arrives with everything needed for the challenge and the samples; you post it back and the results come to your account.
Where this sits next to Meo
Meo Starter (£149) is where most people begin. It is the at-home system: the lipid meter, six months of Meo AI, and a Biological Age Score that updates every time you take a reading. It is designed to be run again and again, so you watch a trend rather than a snapshot.
The KRAFT Test is the deeper, one-off diagnostic underneath it — a direct measurement of your insulin response rather than a pattern inferred from lipids over time. It is the test the science of Meterbolic was built on, and it remains available for people who want the full picture in one sitting.

The KRAFT Test is by appointment — arranged directly with our team rather than bought off the shelf. Email us and we'll confirm a slot, the right route for you (certified clinic or home kit), and which of the two options fits.

The KRAFT Test is an insulin-response assessment intended to inform you and your healthcare professional. It is not a diagnosis of diabetes or any other condition, and it does not replace testing or advice from your GP. Always consult a qualified healthcare professional about your results.
