Introduction: Platelet-rich plasma (PRP) is a technology with potential application in several areas of Medicine and Dentistry. The high variability observed during the production process imposes a challenge for the regulation of its production and use. Objectives: To evaluate current practices of production, storage and use of platelet-rich plasma and related products in Brazil, allowing the identification of operational variability throughout these processes. Method: Crosssectional study with data collection carried out by using a self-applied electronic questionnaire,
with protection of anonymity. Questions were defined based on a literature review and consultation with a specialist in the field. The study questionnaire was sent to researchers and professionals who are producing PRP identified by different strategies, such as previous participation in events and publications in the area. Results: 64 responses were obtained, with 36 complete responses (56.3%) and 28 partial responses (43.7%). The rate of respondents could not be calculated, considering the means for dispatching the questionnaire. For PRP, there was a predominance of use of protocols with double centrifugation and platelet activation by different methods. Most respondents reported using PRP in the areas of orthopedics, physiatry and sports medicine. For fibrin-rich plasma (PRF), there was a predominance of responses using a single centrifugation protocol, without the use of platelet activation methods. Most respondents indicate the use of PRF in areas of dentistry. Variability of procedures and usage profile were observed for all platelet concentrates. Analyses were carried out comparatively according to the three main types of platelet concentrates. Conclusions: Findings corroborate the need to develop regulatory norms aiming at reducing variability and at promoting safety along the production and use of platelet concentrates.
