"When the news broke of the tragedy in South Florida, OneBlood sent O-negative type blood. O-negative type blood is the universal donor and heavily used in trauma situations," said Jonathan McCoun, director of biologics manufacturing for OneBlood. "During situations like this, all hands are on deck."
McCoun said OneBlood collected about 4,500 units of blood on Thursday -- almost double the company's daily intake.
"Please continue to donate," McCoun said. "Blood is always needed 24 hours a day, seven days a week."
OneBlood representatives said employees responded immediately to the shooting Wednesday at Marjory Stoneman Douglas High School by rushing blood over to area hospitals.
The victims were taken to various hospitals, including Broward Health Medical Center, Broward Health North, Broward Health Coral Springs and West Boca Medical Center.
OneBlood has said repeatedly that there is a need to replenish the O-negative blood supply.
People with all other blood types are asked to make appointments at any OneBlood site.
