Packed red cells (PRC)
Packed red blood cells.
PC
Platelet concentrate
Plasma
The non-cellular liquid component of unclotted whole blood. The liquid portion of anticoagulated blood remaining after separation from the cellular components.Plasma is the source of gamma globulin, albumin and clotting factors.
Platelet (PLT)
Thrombocyte.Colorless cells whose main function is to control bleeding. Platelets are essential to normal blood clotting. They can be profoundly depleted during treatment for cancer, leukemia, aplastic anemia and other diseases.
A component derived from fresh whole blood which contains the majority of the original platelet content. Cytoplasmic fragment of megakaryocytes (bone marrow cells).
PPP
Platelet poor plasma
Prion
An infectious proteinaceous particle that lacks nucleic acid, that is, no DNA or RNA, often considered to be the cause of various infectious diseases of the nervous system (such as Creutzfeldt-Jakob disease and scrapie.) Very resilient, not easy to kill.
PRP
Platelet rich plasma
Red blood cells (RBC)
Erythrocyte.Red blood cells transport oxygen to body cells and remove carbon dioxide. Red blood cells contain iron in the hemoglobin.
A component prepared from a single whole blood donation by the separation of the plasma and the buffy-coat layer from the red cells. The relatively large red cells in blood that transport oxygen from the lungs to all of the living tissue in the body. Normally, 40% to 45% of human blood volume consists of erythrocytes.
Red cell concentrate (RCC)
Red cells, buffy coat removed
A component prepared from single whole blood donation by the separation of part of the plasma and the buffy-coat layer from the red cells.
Red cells, cryopreserved
Red cells of a single whole blood donation with most of the plasma removed, deep frozen using a cryoprotectant solution.
Red cells, in additive solution
A component prepared from a single whole blood donation by the separation of part of the plasma with subsequent suspension of the red cells in appropriate nutrient solution.
Red cells, in additive solution, buffy coat removed
A component prepared from a single whole blood donation by separation of part of the plasma and buffy-coat, and with subsequent resuspension of the red cells in appropriate nutrient solution.
Red cells, leukocyte-depleted
A component obtained by removing the majority of leukocytes from red blood cells.
Saline
Salt water, typically isotonic with blood.
Saline adenine glucose mannitol (SAGM)
Preservative solution for red blood cells containing sodium chloride, adenine, glucose and mannitol.
Scapie
A transmissible spongiform encephalopathy similar to nvCJD that occurs in sheep, goats and other animals.
Serum
The noncellular liquid phase resulting from the clotting of a sample of whole blood or plasma. Serum is equivalent to plasma without its clotting elements.
Sickle cell disease
A disease in which the affected person makes defective hemoglobin. Sickle cell disease is inherited.
Transfusion
Replacing blood or blood components a body has lost in surgery, through an accident, or as a result of medical treatment.
Transfusion-related acute lung injury (TRALI)
A new acute lung injury (ALI) within 6 hours of a completed transfusion.
