As part of tomorrow’s Health Fair, LifeStream will conduct a community blood drive on Saturday, May 13, at the Yucca Valley Community Center, from 9 to 2. 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. The Health Fair will see some 30 different health and safety providers and offer free testing and a free healthy meal.
