Plasma is the liquid part of the blood, used for treating bleeding and other disorders. Donated plasma may go directly to hospitals after testing and labeling at the blood center. This is the type of plasma donation in which Carter BloodCare participates. Other than having an anti-clotting agent added, the plasma is not altered in

by William Crews, MD There are many FDA required quality control measurements that must be met to ensure the safety, purity, and potency of blood components before they can be labeled and made ready for patient use. One of the required measurements for every apheresis platelet is calculation of the platelet yield (volume x platelet

by Laurie J. Sutor, MD, MBA Our practice for decades has been to store platelet components at 20 to 24ºC (“room temperature”). This convention likely arose from the finding that platelets stored at refrigerator temperatures have significantly shorter lifespans in circulation after transfusion. However, there are clearly disadvantages of room temperature storage of platelet components:

Surveillance data on platelets stored up to five days have shown that the majority of platelet transfusion-related septic reactions and associated fatalities have occurred with

These include the need for quality control and bacterial testing, the short shelf life, an increase in utilization over recent years, and loss of donors with new regulations. For all these reasons we encourage transfusion services and transfusing
