The quality of platelet concentrates produced by COBE Spectra and Trima Accel cell separators during storage for 7 days as assessed by in vitro methods

Transfusion, 2008
BACKGROUND: The quality of platelet (PLT) concentrates (PCs) can be evaluated with various in vitro methods. A new technique, free oscillation rheometry (FOR), can be used to monitor coagulation properties of PCs and gives information on clotting time and coagulum elasticity. This study compared the quality of apheresis PCs produced by the COBE Spectra

Automated cell count for blood component quality control. [PDF]

Transfusion
Abstract Background Accurate quantification of residual leukocytes (rWBC) and red blood cells (rRBC) in leukoreduced blood components is essential to ensure product quality and transfusion safety. Conventional manual flow cytometry techniques are time‐consuming and analyst‐dependent.

Practices in platelet production: A Nordic perspective (2018-2022). [PDF]

Vox Sang
Abstract Background and Objectives The Nordic region includes Denmark, Finland, Iceland, Norway and Sweden, with a population of >27.5 million. Blood services are managed differently in each country. Current data on platelet concentrate (PC) production methods and capacity are important for developing efficiency and cross‐border preparedness. Materials

Clot formation and resolution properties of platelets during cold storage for 21 days. [PDF]

Transfusion
Abstract Background Cold storage (2–6°C) preserves the aggregatory and clot formation properties of platelets beyond the standard 7‐day shelf life. Comparatively little is known about the effect of cold storage on clot resolution functions, which are necessary to ensure normal hemostatic balance is maintained.

Characterization of the in vitro quality parameters of cold-stored platelets containing aggregates. [PDF]

Vox Sang
Abstract Background and Objectives Cold‐stored platelets (CSP) are being used more widely for the treatment of bleeding because of their longer shelf life. However, storage at low temperatures can induce the formation of platelet aggregates. We aimed to study the impact of aggregate formation on platelet quality and function.

Quality of platelet concentrates after three-day storage following 265 nm ultraviolet C-light-emitting diode irradiation. [PDF]

Transfus Med
Abstract Objectives We aimed to investigate the quality of platelets after storage following irradiation with ultraviolet C (UVC) light‐emitting diodes (LED). Background Controlling transfusion‐related infections, particularly bacterial contamination of platelet concentrates (PCs), is urgently required. UVC‐LEDs have attracted considerable attention as

Preparation of cold-stored platelets on-demand: A novel approach to inventory management. [PDF]

Transfusion
Abstract Background Cold‐stored platelets (CSP) are now being used to treat acute bleeding. However, as CSP are less suitable for prophylaxis, both room temperature (RT) platelets and CSP will be required, which complicates inventory management. The production of CSP “on‐demand” from RT platelets may be a desirable option.
