Resumo
OBJECTIVE:This study is to report a manual method to obtain platelet rich plasma (PRP).METHODS:For this study 61 ml of peripheral blood was obtained and submitted to centrifugation at 541g for 5 min. The centrifugation separates the blood into three components: red blood cells, buffy coat and platelet rich plasma. Blood and platelet rich plasma samples were sent to the Hospital's Laboratory and platelets and leukocytes were measured.RESULTS:A sample of 637 blood donors was evaluated. The platelet yield efficiency was 86.77% and the increase in platelet concentration factor was 2.89 times. The increase in leukocyte concentration factor was 1.97 times.CONCLUSION:The method described here produces leukocyte-rich and platelet-rich plasma with a high platelet and leukocyte increased factor.Level of Evidence IV, Controlled Laboratory Study.
