The community blood supply has reached dangerously low levels that could potentially affect patient well-being. In particular, there is less than a one-day supply of blood. LifeStream will hold a community blood drive on Friday, May 31, at Walmart in Yucca Valley, 58501 29 Palms Highway, from 10 a.m. to 3 p.m. LifeStream 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
