- Collect in citrate anticoagulant, separate plasma from whole blood within 4 to 6 hr. of collection, store frozen for up to 1 year.
- Platelet rich plasma
- Collect in citrate anticoagulant, separate platelet rich plasma from whole blood within 4 to 6 hr. of collection, process and store at room temperature, transfuse within 48 hr. of collection.
- Packed Red Cells
- Collect in citrate anticoagulant, separate from whole blood within 4 to 6 hr. of collection, combine packed cells with additives for sustained red cell viability, store under refrigeration (4 to 8 C) for up to 4 weeks.
- Plasma Cryoprecipitate
- Prepared from fresh frozen plasma, store frozen for up to 1 year, unit size varies, check with each supplier for dosage.
- Cryosupernatant
