  • The need for blood donations is constant.  Patients in Oklahoma hospitals have needs 365-days-a-year, whether it's for scheduled treatments or for emergencies.  Since there is no substitute for human blood, supplies must be constantly renewed.
  • Of the 38% of those who are eligible to donate blood in the U.S., less than ten percent actually donate each year. 
  • Every two seconds someone needs blood.  Each unit of blood donated can save the lives of up to three people.
  • Although all blood types are needed, those with O Negative type blood are especially encouraged to donate.  According to American Association of Blood Banks (AABB), those with O Negative blood type make up only nine percent of the national population; however, O Negative blood can be used by anyone in emergency need when a patient's blood type has not yet been identified.
