Abstract

Certain examples describe systems and methods for increasing plasma extracted from donor blood. An example method includes receiving blood extracted from a donor connected to a blood collection machine. The example method includes filtering the blood using a filtration device to remove at least a portion of plasma included in the blood to separate the plasma removed from remaining blood. The example method includes routing the plasma removed for collection. The example method includes re-filtering the remaining blood using a or the filtration device to remove additional plasma from the remaining blood. The example method includes routing the additional plasma removed for collection.
