Assessment of quality of platelets preserved in plasma and platelet additive solution: A Malaysian experience.

Background: A use of platelet additives solution (PAS) improves storage conditions so as to give increased shelf life to platelets and to maintain hemostatic function.

Objective: The present study was aimed to compare in vitro quality of platelet rich plasma (PRP)-derived platelet concentrate (PC) during extended period of storage in plasma and in additive solution (Composol PS and Fresenius).

Study Design: Randomized 19 PCs each were used in the study for plasma and PAS as the storage medium.

Red cell phenotyping of blood from donors at the National blood center of Malaysia.

Background: Human blood groups are polymorphic and inherited integral structures of the red cell membrane. More than 300 red cell antigens have been identified and further categorized into 30 major discrete systems. Their distribution varies in different communities and ethnic groups.
