Systems and methods take into account that the spleen normally holds a number of platelets in reserve out of circulation. During blood procesing, the spleen releases these platelets into the donor's circulatory system, making them available for collection. The systems and methods estimate the number of platelets N SPLEEN held in reserve by the spleen in a human body. The systems and methods derive a splenic mobilization function Spleen, which can be expressed as a function of a precount of platelets Plt PRE. The systems and methods estimate N SPLEEN where: N SPLEEN = Spleen-1 x Plt PRE x DonVol where DonVol is blood volume in the body. The systems and methods can also estimate the total number of platelets N PLT in a human body, taking the Spleen function into account, where: N PLT = Plt PRE x Spleen x DonVol.
