name
descriptionVolume of blood removed during a therapeutic phlebotomy. Therapeutic phlebotomy is relatively safe and efficient at depleting iron stores in the body; thus, this procedure is effective for treating patients with hemochromatosis, polycythemia vera, and related conditions. A therapeutic phlebotomy is indicated as an integral component of the treatment of several medical conditions. It is the cheapest and most effective method for removing excess iron in nonanemic patients. A therapeutic phlebotomy is performed in a medically supervised environment. It is commonly performed in a blood donor center, apheresis unit, physician office, or at home by a well‐trained phlebotomist, but home phlebotomy is rarely performed. https://pmc.ncbi.nlm.nih.gov/articles/PMC6448745/
