Factors potentially affecting platelet activation
| Collection and preparation factors |
| Flow rate of collection |
| Type and concentration of anticoagulant |
| Fractionation process (platelet-rich plasma vs buffy coat methods) |
| Centrifugation force and time |
| Resting period before suspension |
| Storage bags |
| Composition including permeability and plasticizers |
| Conditions of storage |
| Volume and cell concentration |
| Storage medium (storage solution vs plasma) |
| Type of rotation |
| Product modification |
| Concentration to reduce volume |
| Washing to remove plasma or supernatant |
| Irradiation |
| Pathogen inactivation |
| Cryopreservation |
