To understand the difference between major components and minor fractions, it might help to use the example of a lemon. About 40 years ago, blood banks started moving away from keeping whole blood and began separating it into components (packed cells, platelets, plasma, etc.) Transfusion of whole blood is being used in the military setting and is being studied in pre-hospital trauma care and in the setting of massive transfusion in the civilian setting.[12][15][16][13]. 1. Whole blood recipients (2016–2019) were compared to a propensity-matched cohort who received at least 1 uncrossmatched red blood cell unit in the trauma bay (2013–2016). Plasma, white blood cells, red blood cells, platelets. Components of Whole Blood. - to prevent bacterial over growth. [2] It is used to make a number of blood products including packed red blood cells, platelet concentrate, cryoprecipitate, and fresh frozen plasma. Most in vitro models that test blood components do not use proportional volumes of these blood products and instead use large ratios compared to the patient’s blood volume. PubMed. This is done to provide a final product with a very specific hematocrit (percentage of red cells) with type O red cells and type AB plasma to minimize the chance of complications. Substances taken out of these four components are called minor fractions. Whole Blood and Components. Blood is a specialized body fluid. These include red blood cells (RBCs), white blood cells, and other components. 38% of the population in the United States are eligible to donate blood, but only 3% of us actually donate. The blood in your body is called whole blood, and it has four major components: platelets, red blood cells, white blood cells and plasma. An appointment to donate whole blood can take as little as one hour, and the actual donation is only 8-10 minutes of that time. Most blood banks now split the whole blood into two or more components,[17] typically red blood cells and a plasma component such as fresh frozen plasma. Whole blood. But what about trauma? Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues; forming blood clots to prevent excess blood … It has four main components: plasma, red blood cells, white blood cells, and platelets. Because of contaminating red cells, granulocyte components must be ABO and RhD compatible and crossmatched with the recipient. Components of blood. The components of human blood are: Plasma. This enables storage of the components under conditions that optimise their quality for as long as possible, and enables transfusion of only the required components to each recipient.
