Blood Plasma - Overview
Plasma donation is one of the ways to help people suffering from certain illnesses. It does not do any harm to a donor and is quite important for a recipient.
In a human body, blood cells are normally suspended in the yellow-colored component of the blood known as blood plasma. This substance accounts for 55% of the entire blood volume. Plasma contains approximately 90% of water and the remnant 10% is made of a variety of substances such as dissolved proteins, glucose, clotting factors, mineral ions, hormones etc. If fibrinogen and other blood clotting factors are removed from blood plasma blood serum is obtained.
There are certain criteria when it comes to plasma donation. The requirements may only slightly differ from country to country but in many countries they are basically the same.
