When you come in for the O-Shot procedure, you’ll have a sample of blood drawn. Thomas Pulice, PA-C uses this blood sample to make platelet-rich plasma. Your blood goes into a centrifuge that spins quickly to separate platelets. These platelets are then made into a platelet-rich plasma gel that he injects into the targeted areas. These injections usually don’t take long. In fact, they take just 20 minutes, although this can vary from patient to patient. Thomas Pulice, PA-C will let you know how long your procedure should take.
