Why this test

ApoB reflects the number of cholesterol-carrying particles that can enter artery walls, while LDL cholesterol measures the cholesterol carried inside LDL particles.

In about 20% of patients, LDL cholesterol and ApoB results disagree. ApoB reflects all of the particles that can lodge in artery walls, including LDL, VLDL, IDL and Lp(a). The Australian cardiovascular risk guideline does not include ApoB in routine risk assessment and sets no ApoB target, so your GP reads ApoB alongside your standard cholesterol results.

Understanding your results

Elevated

Worth discussing with your healthcare practitioner - lifestyle factors may help

Typical range

Your ApoB is in the ideal range for cardiovascular health

High

Recommend discussing management options with your healthcare practitioner

Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.

ApoB is newer to clinical practice. Many cardiologists now consider it the superior marker, but it's not yet part of standard testing. We include it because the evidence supports its value.

LDL-C measures the amount of cholesterol in LDL particles. ApoB measures the number of atherogenic particles. You can have normal LDL-C but elevated ApoB if your particles are small and dense.

No fasting is required for ApoB testing.

Results are typically available in 3 to 5 business days via your dashboard.

Is a Lipid Panel Worth It?

Half of heart attacks occur in people with "normal" cholesterol. Standard lipid panels miss critical risk markers—ApoB counts the particles that actually matter, not just the cholesterol they carry.

ApoB: why 2026 ACC/AHA and NLA guidelines centre it for heart risk

The 2026 ACC/AHA dyslipidemia guideline (co-authored by the National Lipid Association) gave ApoB an official seat in the heart-risk algorithm. With 10-20% of people having "normal" LDL but elevated particle numbers, this is the test that catches the risk cholesterol misses.
