Platelet rich plasma is being increasingly used in the modem medicine as a material, stimulating regeneration and accelerating tissue healing. Platelet rich plasma is an autologous platelet concentrate, which is obtained from the peripheral blood of the patient. The method of extraction is based on the isolation of platelets during centrifugation of the whole blood, drew on anticoagulant. With the difference in density between the various cellular components of blood, such as red blood cells, buffy coat and platelet poor plasma, the separation into individual fractions is possible. At the present moment no optimal method of preparation of the platelet rich plasma has been found. On the market there are a number of commercial collection systems available, differing from each other in centrifugation parameters, type of container to which blood is collected and anticogulant used. Unfortunately, this can lead to obtaining platelet rich plasma with a varying number of platelets, leukocytes and resulting in a different concentration of growth factors. This is important, because the studies show, that a positive clinical effect depends on the quality of the used platelet-rich plasma.
