A plasma donor is an individual who voluntarily gives their blood plasma, a yellowish fluid that makes up about 55% of blood. Plasma contains water, electrolytes, proteins, and waste products, and is essential for various bodily functions. Donating plasma is a safe process that typically takes about 1 to 2 hours, during which blood is drawn, plasma is separated, and the remaining components are returned to the donor. Plasma is crucial for producing life-saving treatments for conditions such as hemophilia, immune deficiencies, and burns. Plasma donations are often collected at specialized centers, and donors may receive compensation for their time. Regular donations can help ensure a steady supply for those in need.
