The PRP procedure may appear to take a long time. Your blood must first be drawn into syringes. The sample must next be treated in a centrifuge. Cleaning the blood to make it suitable for transfer and injection, as well as sorting the components of your blood by mass, are all part of this process. It takes very little time to draw your blood. The centrifuge will only take three to five minutes to process your blood. Finally, depending on the size and number of regions to be treated, the therapy takes anywhere from 30 to 60 minutes.
