Blood drives are considered an essential service, and blood donations are way down due to the pandemic. Blood is desperately needed; a blood drive will be held tomorrow from 9 a.m. to 2 p.m. Saturday, April 24, in Yucca Valley at the Center for Healthy Generations (57121 Sunnyslope Drive). All blood donors must wear a face mask and undergo a COVID-19 health screening on arrival. All donors should be free of infections or illness, weigh at least 115 pounds, and not be at risk for AIDS or hepatitis. Donors will receive a free cholesterol screening and incentives. To make an appointment to donate blood, call 800-TRY-GIVING.
