An in vitro pilot study of apheresis platelets collected on Trima Accel system and stored in T-PAS+ solution at refrigeration temperature (1-6°C).

Refrigerated PLTs stored in T-PAS+ for 18 days met FDA pH standards. Functional metrics suggest activity of T-PAS+-stored PLTs and the potential to contribute to hemostasis throughout 18 days of storage. Extending the shelf life of PLTs would increase access to hemostatic resuscitation for bleeding patients in military and civilian settings.
