Review of concentration yields in commercially available

Platelet-rich plasma (PRP) is currently solely char-acterized by its absolute platelet concentration: it is a plasma volume with any platelet concentration above that of baseline whole blood, which is 150 000/µL1 to 450 000/µL.2 While PRP was first used in the 1970s for wound and bone healing in the field


elapsed, the units should be returned to the blood donor center where they can be processed into RBC units. The platelet-rich plasma supernatant must be discarded. The final RBC units can be distributed to transfusion services. The RBC units must retain the original expiration date of the collection.

Platelet-Rich Plasma: Properties and Clinical Applications

The platelets are concentrated in the platelet rich plasma at levels generally 6 to 8 times the baseline levels. The resultant PRP is stored at room temperature until needed, at which time 10,000 units of powdered bovine thrombin is mixed with 10% calcium chloride. Next, the PRP is drawn into a 10ml syringe. The thrombin/calcium-

Abstract Platelet-rich plasma (PRP) is a natural concentrate of autologous blood growth factors experi-mented in different fields of medicine in order to test its potential to enhance tissue regeneration. The aim of our study is to explore this novel approach to treat degenerative lesions of articular cartilage of the knee. One hundred con-

By 2004, approximately 25% of platelets supplied nationally were provided as apheresis platelets increasing to 37% in 2008/09 with wide variation amongst the jurisdictions.

Stimulation of IL-1ra Production From Platelet-Rich Plasma

To date, levels of IL-1ra have not been quantified from an autologous platelet-rich plasma (PRP) preparation.The purpose of this study was to quantitate the IL-1ra found in a PRP. A secondary purpose was to attempt to increase the IL-1ra found in the PRP by incubation in a plasma concentration device.
