LifeStream will conduct two community blood drives at Walmart in Yucca Valley. The first blood drive is set for Saturday, December 23, and the second one is Tuesday, December 26. Both blood drives will be held from 10 to 3. Due to a nationwide blood shortage, all blood types and all types of blood donations are needed. Donors will receive incentives. In addition, LifeStream 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.
