To combat the shortage, the Orange County Red Cross chapter is hosting two blood drives on UNC's campus this week.
The goals for Tuesday and Wednesday's drives are 55 and 50 units, respectively. The drives will be held in the Great Hall. Participants in the drive can receive a calculator, a coupon for a Chick-fil-A sandwich, Domino's pizza and, of course, the traditional cookies and juice.
The blood collection division of the Red Cross operates not by states or counties but by regions. Orange County falls in the Blood Services Carolinas Region, which extends from Wilmington across the state to Johnston City, Tenn.
Casey Copp, a representative of the Orange County Red Cross, said the area tries to keep at least a two-day supply of each blood type on hand at all times.
"We use about 1,500 units daily in the region," Copp said. "We are currently at a two-day supply for most types."
Copp said the Red Cross has less than a two-day supply in blood types O+, O-, B+ and B-.
Jeff Davis, the donor resources development representative for the Blood Services Carolinas Region, said the blood shortage is not unprecedented.
"During the summer, we're always seeing our lower levels," he said. "When our supply level drops below three days, we start to get concerned."
Davis said the lack of blood is brought about by schools being out for the summer and not holding blood drives, potential donors being on vacation and a larger number of deferrals due to iron deficiencies.
