Apheresis is the most widely used procedure to obtain high yield and quality platelet concentrates and to improve transfusion therapies in thrombocytopenic patients, oncohematological patients, surgical patients and even patients with adverse clinical factors to refractoriness. Objective. To determine the efficacy of a cell separator in the collection of platelets in a National Health Institute in Lima. Material and methods. Descriptive study; the sample consisted of 80 platelet concentrates, obtained by plateletpheresis and using American cell separator equipment. The platelet collection was performed in a Hemotherapy and Blood Bank service of a health institution in Lima, during the months of February to July 2018. Effectiveness was performed by evaluating performance, efficiency and compliance with approved quality standards. One of the parameters used was the residual platelet and leukocyte count, processed in the hematological analyzer. Results. The evaluations were: average platelet concentration per platelet concentrate (yield)= 3.4 x 1011 platelets/ml, residual leukocyte count = 0.07 x 10 6 leukocytes/ml, average volume of blood processed = 2480 ml, average final volume = 217.5 ml, collection efficiency = 56.9 to 63.9 %, average time per collection procedure = 72 minutes. Conclusions. The platelet concentrates obtained with the plateletpheresis procedure comply with national and international quality standards, therefore, it is concluded that this procedure is effective in the collection of high quality products that achieve transfusion efficiency.
