Signal · ApoB

LDL is the amount. ApoB is the count.

LDL-C measures the total cholesterol packed into your "bad" lipoproteins. ApoB counts the particles themselves. It is the particles — not the cholesterol inside them — that enter the artery wall and drive atherosclerosis. That's why ApoB is the more honest cardiovascular risk signal, and why it belongs on every Radar.


The ranges that matter

Fewer particles. Less risk.

Standard lab reference ranges top out much higher than what is metabolically healthy. These targets reflect coaching practice for people who want to extend healthspan, not just avoid immediate diagnosis. Your Radar scores every marker 0–100 on the same four-band continuum you see on your report: Fit (90+), Well (50–89), Short of well (26–49), Sick (25 and under). A score of 25 is the diagnosable line at any age. The values below are the age-40 reference — the bands shift with your age and sex, so use the calculator underneath for your own numbers.

Fit
≤ 76 mg/dL (M) · ≤ 73 (W)
Low particle burden. The strongest long-term cardiovascular signal on the panel.
Well
76 – 109 mg/dL (M) · 73 – 106 (W)
Inside typical lab “normal” but above optimal for a long healthspan. Particle count still accumulating arterial exposure.
Short of well
109 – 130 mg/dL (M) · 106 – 130 (W)
The Radar scores 25 at 130 mg/dL. High particle burden with meaningful atherosclerotic risk over decades.
Sick
≥ 130 mg/dL
Very high particle count. Worth a lipidology conversation as well as the coaching levers below.

What it reveals

Every particle carries one ApoB.

Every atherogenic lipoprotein — VLDL, IDL, LDL — is wrapped in a single molecule of apolipoprotein B. So when you measure ApoB, you are literally counting the number of those particles circulating in your blood. That count is what determines how many chances a particle has to lodge in an artery wall and start the atherosclerotic process.

LDL-C reports the total cholesterol inside those particles. Two people can have the same LDL-C with very different particle counts — and very different cardiovascular risk. The person with many small, dense particles is at much higher risk than the person with few large, buoyant ones. ApoB tells you which you are.

This is why ApoB is increasingly recommended as the primary lipid marker for cardiovascular risk. It reflects the physical reality of atherogenesis: a particle is what hits the wall, not the cholesterol inside it.

Why it belongs with Regulate Energy ApoB is where the other three Regulate Energy markers eventually show up. When insulin resistance develops, the liver produces more VLDL particles. When TG:HDL drifts, particles become smaller and denser. ApoB is the downstream consequence — the cardiovascular expression of fuel regulation over time.
