double red blood vs whole blood donations

  1. PAUL-E

    Double red blood vs whole blood donations effect on hematocrit, which is more effective?

    Like the title says does anyone know if double red blood or whole blood donations is more effective in keeping hematocrit lower long term? I know the difference between the two but was just curious if one was more effective than the other say if someone's hematocrit rises fast for example...
