Introduction to Blood Donation
Blood donation happens when a person voluntarily agrees for his or her blood to be extracted and donated to a person in need. It is an altruistic gesture as the donated blood may be used for an emergency transfusion or can be separated into individual components to be used later.

Donating blood is easy and safe for most people, and typically, it is mandatory for potential donors to consent to donate their blood. People who are potential donors are physically examined by a physician. Their blood is screened for diseases such as viral hepatitis and AIDS, that can be easily transmitted through these blood donations.
