About
A clinic that measures first.
Four physicians, one exercise physiologist and a townhouse in Chamberí. One scanner, one protocol and one reader for every test, so the next result can be compared with the last.
The consultation room at Fortuny 14. Two chairs, one window, no desk between them.
Why Kerno exists
Most people have their first heart attack with a normal cholesterol on file.
Elena Ruiz spent eleven years in the cardiovascular risk unit at La Paz seeing people after their first event. Most had a normal LDL on their last check. Many had an ApoB that would have told a different story, and nobody had measured it.
In 2021 she opened Kerno with Javier Moreno, who had run the sleep unit at Gregorio Marañón for seventeen years. The idea was narrow: measure the numbers that predict trouble ten years out, read them together, and measure them again before changing anything.
The clinic is one townhouse on Calle de Fortuny with four rooms: a draw room, a DEXA, a lab with a metabolic cart and the room in the photo. Each physician keeps a list of 150 members at most. When a list is full, it closes.
We do not sell supplements, we do not prescribe on request and we do not promise years. We tell you where you stand and which numbers you can move.
How we work
Four rules we do not bend.
Written down in 2021 and unchanged since. Every plan we write has to pass all four.
- 01
We measure before we advise.
No plan is written until the baseline is read. A recommendation without a number behind it is an opinion, and you can get those for free.
- 02
One reader for each kind of test.
Andrés Soler reads every scan and Elena Ruiz every lipid panel. The same eyes, the same way, so a change between two results is a real change.
- 03
A trend decides, not a single value.
A plan changes when two results in a row point the same way. One surprising tube of blood gets a retest, not a new prescription.
- 04
Your results leave with you.
Every result exports at any time, as a PDF and as raw data. No employer, insurer or partner sees a number without your signature.
