In the 2017-2018 school year, high school students contributed 22% of all blood components collected by Inova Blood Donor Services. By starting to donate in the teen years, you can set up a life-saving habit that could help affect hundreds of lives in the years ahead. With each whole blood donation, a blood donor can save up to three lives. In addition, many local high schools require students to complete volunteer hours prior to graduation. We are happy to have volunteers to help us at our larger blood drives, and can sign off on volunteer hours once they are completed.
