LifeStream will conduct a community blood drive on Tuesday, December 19, at Hi-Desert Medical Center, from 10 to 2. Due to a nationwide blood shortage, all blood types and all types of blood donations are needed. Donors will receive incentives. In addition, Desert Blood Services now offers donors free cholesterol screening with every blood donation. All prospective donors should be free of infections or illness, weigh at least 110 pounds, and not be at risk for AIDS or hepatitis. To make an appointment to donate blood, call 800-TRY-GIVING.
