phlebotomy

noun

phle·​bot·​o·​my fli-ˈbä-tə-mē 

plural phlebotomies

: the drawing of blood (as by venipuncture) for transfusion, apheresis, diagnostic testing, or experimental procedures

Note: Phlebotomy was once widely used to treat many types of disease but is now limited to the treatment of only a few conditions like hemochromatosis and polycythemia vera.

While scientists struggle to understand the molecular subtleties of hemochromatosis, the clinical treatment of the disorder remains remarkably primitive: serial phlebotomy. That is, weekly bloodletting.
