Quantification of growth factors by using a new system for obtaining platelet-rich plasma.

Objective: To verify the performance of a new method for obtaining platelet-rich plasma, while avoiding contamination of the sample during its processing.

Study Design: Twenty healthy patients were selected, from whom 21 ml of blood was extracted. We then proceeded to study the platelets and growth factors in basal blood after centrifuging the sample by using a new closed system for obtaining platelet-rich plasma (PRP).
