Detailed explanation-1: -When researchers put the sample through a centrifuge, a machine that spins the blood, those WBCs and platelets combine to form their own layer suspended between the red blood cells (RBCs) and supernatant plasma. This thin layer is called a buffy coat because of its color (yellowish to brownish).
Detailed explanation-2: -The term “buffy coat” might make you think of a shiny car wax, but in the world of blood banking, buffy coat refers to the white layer between red blood cells and plasma in a unit of whole blood after it has been spun down in a centrifuge. The buffy coat contains white blood cells, the soldiers of the immune system.
Detailed explanation-3: -A buffy coat is a concentration of white blood cells (WBCs) and platelets. WBCs and platelets make up only around 1% of the cells in the volume of peripheral whole blood.
Detailed explanation-4: -The straw-colored fluid that forms the top layer is called plasma and forms about 60% of blood. The middle white layer is composed of white blood cells (WBCs) and platelets, and the bottom red layer is the red blood cells (RBCs).
