Heart & metabolic testing · UK

Most heart attacks don't come from nowhere. The warning signs are in your blood — years earlier.

We test the advanced markers your GP doesn't check — so you can act before there's a problem.

Why Byolete
Your GP's cholesterol test was never designed to catch heart disease early

Routine NHS tests measure the same numbers they've always measured. The markers that actually predict cardiovascular risk go completely unchecked.

ApoB

The particle that causes heart attacks — not tested by your GP

ApoB counts the dangerous particles that stick to artery walls. It predicts heart attack risk far better than standard cholesterol — and it's absent from every routine NHS panel.

Lp(a)

A genetic risk 1 in 5 carry — and most never find out

Elevated Lp(a) significantly raises your lifetime risk of heart attack and stroke. It's inherited, can't be changed by diet, and almost nobody in the UK has been tested for it.

hs-CRP

Silent inflammation quietly damaging your arteries for years

Chronic low-grade inflammation is one of the main drivers of cardiovascular disease. hs-CRP detects it early — long before symptoms appear or routine tests flag anything.
