Should I use LDL or ApoB?

ApoB is mechanistically more accurate (counts the atherogenic particles directly). LDL is the legacy standard and still widely used. Run both if you can.

LDL Cholesterol (LDL-C)

LDL cholesterol is the most-tracked cardiovascular risk marker. It correlates with — but is not the same as — atherogenic risk; ApoB is the better single read. LDL targets depend on overall cardiovascular risk profile.

Category: Lipids
Units: mmol/L
Reference range: <3.0 mmol/L (general); <2.0 mmol/L (high CV risk)

What does a high LDL Cholesterol result mean?

Genetic (familial hypercholesterolaemia), diet, low thyroid, nephrotic syndrome, ageing.

What does a low LDL Cholesterol result mean?

Often genetic. Very low can suggest malabsorption or liver dysfunction.

Why does LDL Cholesterol matter?

Single best-validated lipid lever. Always interpret alongside HDL, triglycerides, and ideally ApoB.
