Your Cholesterol Test Is Counting the Wrong Thing

Your cholesterol test came back normal, so your arteries are fine, right? Drew, why are you making that face?

Because that test measures the cargo, not the vehicles. It's judging traffic by counting passengers.

Same passengers, different traffic?

Exactly. Twenty big buses or fifty tiny ones. Same people aboard, but way more fender benders with the fifty.

So what should we be counting instead?

ApoB. Apolipoprotein B, an ID badge stamped on every artery-clogging particle. Each particle wears exactly one, so counting badges counts particles.

And what's the particle itself?

A lipoprotein, a fat-and-protein bubble ferrying cholesterol through your blood. LDL, VLDL, the leftovers, and Lp(a) all carry the badge. HDL doesn't.

Why do the badge-wearers cause trouble?

Some slip into the artery wall and stay put, like a burr on a wool sweater. More particles, more burrs.

Honestly, that's the most relatable thing about arteries I've ever heard.

I peaked. Okay, Monday morning: ask your doctor to add an ApoB test to your next blood draw. It's just a blood test.

And Lp(a)? You said inherited.

Right, it's mostly genetics, so it's worth checking once. Lifestyle barely moves it.

What about lowering the regular particles? Please say it's not kale smoothies.

Research points to the boring stuff: less saturated fat, more fiber, regular exercise, and a healthier weight. Statins are the main medication, and your doctor decides that based on your risk. Supplement evidence is thin.

So what's the takeaway?

Next blood draw, ask for ApoB. Don't just count the passengers, count the buses.
