Centrifuge Settings For Blood - diakonie-annaberg.de

2) Separation (Vet Clinic Guide) It is clear now that the foundation of PRP therapy is the concentration of platelets from the patient’s blood. Inside a single drop of blood, there are approximately 4 platelets; after separation, a drop of plasma should contain 10 to 15 platelets. This separation process is rather simple, since it mainly involves the use of the centrifuge and …
