a highly selective method for the removal of apolipoprotein-b-containing serum lipoproteins ( low density lipoproteins [ ldl ] and very-low-density lipoproteins [ vldl ] ) from hypercholesterolaemic patients by immunoadsorption in an extracorporeal system consists of separation of plasma from the blood cells by a blood-separation centrifuge , followed by the selective adsorption of ldl from the plasma effluent , from which high-density lipoproteins ( hdl ) and other plasma proteins are not removed , is returned to the patient with the blood cells .
