Desert Blood Service will hold a blood drive tomorrow in Twentynine Palms at Little Church of the Desert, 6079 Adobe Road, from 2 to 6:30 p.m. Donors receive free cholesterol screening and donor reward points that may be redeemed in the online donor store at www.desertbloodservices.org. Healthy individuals at least 15 years of age may donate blood. All prospective donors should be free of infections or illness, weigh at least 110 pounds, and not be at risk for AIDS or hepatitis. Donors receive a free mini-physical as part of the donation process. Donating blood takes about an hour, yet gives someone a lifetime. For more information, please call 760-777-8844.
