Acid-citrate-dextrose
Acid-citrate-dextrose (pronunciation: /ˈæsɪd ˈsɪtreɪt ˈdɛkstroʊz/) is a solution of citric acid, sodium citrate, and dextrose in water. It is used as an anticoagulant in the process of collecting and storing whole blood and blood components, particularly platelets.
Etymology
The term "Acid-citrate-dextrose" is derived from the three main components of the solution: citric acid, sodium citrate, and dextrose. The term "acid" refers to the citric acid component, "citrate" refers to the sodium citrate component, and "dextrose" refers to the glucose component.
Usage
Acid-citrate-dextrose is used as an anticoagulant to prevent the clotting of blood during collection and storage. It works by chelating the calcium ions in the blood, which are necessary for the clotting process. The dextrose component provides an energy source for the red blood cells.
