platelet concentrate

platelet concentrate

A blood product prepared from a single donor, which transiently increases platelet count by 5-10 x 109/L/m2 body surface area (5–10,000/µL) if thrombocytopaenia (decreased platelet count) is not due to increased platelet destruction.

Thresholds
Bleeding due to thrombocytopaenia is unlikely if the platelets are > 50,000/µL, and highly likely at a platelet count of < 5,000/µL. The grey zone between these two depends on local practice, with most platelet concentrates being administered at < 10,000/µL.

Adverse reactions
Febrile transfusion reactions are related to bioreactive substances (IL-1β and IL-6) in supernatant, which increases with increased storage and increased number of leukocytes in stored unit.

platelet concentrate

Platelets prepared from a single unit of whole blood or plasma and suspended in a specific volume of the original plasma. This blood fraction must be used before the expiration date shown on its label. Platelets are stored at room temperature (22°C) either in plasma or in a concentrated form as platelet-rich plasma.
