Rosenbaum 2012 predicted daily CD34+ leukapheresis yield
Rosenbaum 2012 predicted daily CD34+ leukapheresis yield: (peripheral_cd34_per_ul * 0.30 / weight_kg) * processed_volume_l, as ×10^6 cells/kg. Uses that paper's adjusted collection efficiency of 30% only. Weight via weight_kg or weight_lb. Deterministic published arithmetic with citation. Not an apheresis order; magent does not run the collection, choose a machine, or set a collection goal.
