What is the medical procedure that facilitates lead removal from blood?

Chelation therapy is the medical procedure that facilitates lead removal from the blood. This technique involves the use of chelating agents, which are substances that bind to heavy metals such as lead. When these agents are introduced into the bloodstream, they form a stable complex with the lead ions, allowing for their excretion through the kidneys and urine. This process is particularly effective in cases of lead poisoning, where removing lead from the blood is crucial to prevent further health complications.

Other procedures listed, such as blood transfusion, dialysis, and plasma exchange, serve different primary functions. Blood transfusions are used to replace lost blood or treat certain medical conditions, dialysis is utilized to filter waste products from the blood in individuals with kidney failure, and plasma exchange involves removing and replacing the plasma component of blood to treat specific diseases. While these may be important medical procedures, they do not specifically target lead removal like chelation therapy does.
