What does the buffy coat consist of?
The buffy coat is simply a concentration of all the white blood cells and platelets in a sample of blood . To prepare a buffy coat, a special machine spins the blood sample in a small circle at very high speed in a process called centrifugation (much like a spinning ride at an amusement park).

What percentage of blood is water?
Over 90% of blood plasma is water, while less than 10% consists of dissolved substances, mostly proteins. Blood plasma also contains electrolytes, vitamins and nutrients such as glucose and amino acids. Over 99% of the solid particles in blood are cells known as red blood cells (erythrocytes) due to their red color.
