Which particles are included in non-HDL cholesterol?

Non-HDL cholesterol represents the cholesterol carried by all atherogenic lipoproteins, excluding HDL. It’s effectively total cholesterol minus HDL cholesterol. The main particles that contribute to this pool are LDL, VLDL, and IDL, since they carry cholesterol that promotes atherosclerosis. HDL, in contrast, is anti-atherogenic and is not included in non-HDL. In fasting blood samples, chylomicrons are typically absent, so the non-HDL fraction mainly comprises LDL, VLDL, and IDL. That’s why the option listing LDL, VLDL, and IDL best fits non-HDL cholesterol.
