Summer Blood Drive in Support of the American Red Cross 07/13/2015 Spectrum Healthcare Resources holds a quarterly blood drive, in support of the American Red Cross, at our corporate office in St. Louis, Missouri. Our most recent blood drive was held on July 13 and we are pleased to announce that 21 people signed up to participate in the event. Each person typically donates 1 pint of blood, which can save up to three lives. A total of 30 million blood components are transfused each year, and 41,000 blood donations are needed daily. Spectrum is proud of our employees for donating and supporting the efforts of the American Red Cross. In the past 6 years, Spectrum has recruited 328 total donors, held 28 blood drives, and donated 560 units of blood.
