ABSTRACT:
Methods and apparatus are disclosed for separating and collecting blood fractions or components such as platelets. A first anticoagulant solution is added to whole blood, which is then separated into platelet-rich plasma and red cells. A second anticoagulant is added to the platelet rich plasma, which is then separated into platelet-poor plasma and platelet concentrate. The rate of red cell sedimentation is increased and the time of the separation/collection procedure may be reduced when the pH of the first anticoagulant is greater than approximately 6.0.
