Local breweries are going head to head for a battle, seeing which location can get the most blood donations by the end of the day.

According to the Red Cross Blood, every two seconds, someone in the U.S. needs a blood transfusion. Every day, 36,000 units of red blood cells are needed.

The Coastal Bend Blood Center is encouraging anyone who is eligible to donate.

The Blood Center provides blood for patients at 20 medical facilities in 10 Coastal Bend counties.
