While the same ABO group of the patient is usually the first choice for red cells, platelets and plasma transfusions, there may be some circumstances where non-identical ABO compatible components may be provided.
Blood components must be stored in an appropriate temperature-controlled environment. Failure to follow correct storage requirements may result in decreased transfusion efficacy, potential harm to the patient or result in the component being unsuitable for use.
A range of valuable products are manufactured from plasma through a process called fractionation. This is when different types of proteins found in plasma are separated, purified and concentrated into therapeutic doses.
