How to understand cholesterol types

Total cholesterol is the sum of all cholesterol types. LDL ("bad" cholesterol) is linked to vascular risk; HDL ("good" cholesterol) is considered protective. Triglycerides are blood fats. Reference ranges vary by lab; targets depend on your cardiovascular risk. Discuss your result with a doctor. For a deeper marker-by-marker view, compare with our LDL cholesterol and LDL vs HDL guides, plus dedicated explainers for ApoB and Lp(a).
