(KAIT/NBC) - Blood donations for all blood types are critically low.
The American Red Cross is dropping the letters from its logo, hoping the glaring illustration of the missing letters will encourage blood donations.
Mastercard, State Farm, and Oreo are doing the same thing.
Officials say 38 percent of the population is eligible to donate blood but only three percent ever do.
Dagny McDonald says her son, Jensen, has sickle cell disease. Blood transfusions, every three weeks, help him avoid the excruciating pain associated with sickle cell.
"Without that -- he would be in the hospital," McDonald said. "He would have pain. The blood transfusions have kept him out of the hospital."
Blood donations help many kids of patients, not only sickle cell, but also cancer patients and accident victims.
