The American Red Cross of Utah and Calvary Baptist Church are asking Salt Lake City residents to give blood during the church’s Getting in the Know Health Fair on Saturday, May 9, part of a community effort to strengthen the blood supply and support the health and well-being of local families. The Red Cross blood drive will be held from 8 a.m. to 2 p.m. at Calvary Baptist Church, 1090 S. State Street in Salt Lake City. The health fair runs from 8 a.m. to noon and will bring residents together with health providers, wellness organizations and community partners for screenings, resources, a 1-mile walk and information focused on improving community health. There will also be a free sickle cell trait screening for a limited time.
