Is
donating blood safe?
How long does it take? 56 Blood Facts
1. Anyone in good health, at least 17 years old, and at least 110 pounds may donate blood every 56 days, or every two months. There is no upper age limit. We have donors in their 80's!
15. Shortages of all blood types happen during the summer and winter holidays.
25. People donate blood out of a sense of duty and community spirit, not to make money. They are not paid for their donation. 26. Much of today's medical care depends on a steady supply of blood from healthy donors. 27. One unit of blood can be separated into several components: red blood cells, white blood cells, plasma, platelets and cryoprecipitate. 28. Red blood cells carry oxygen to the body's organs and tissue. 29. One billion: the number of red blood cells in two to three drops of blood. 30. Red blood cells live about 120 days in the circulatory system. 31. Platelets support blood clotting and give those with leukemia and other cancers a chance to live. 32. Apheresis (a-fer-EE-sis) is a special kind of blood donation that allows a donor to give specific blood components, such as platelets. 33. 42 days: the shelf life of donated red blood cells. 34. Five days: the shelf life of donated platelets. 35. One year: the shelf life of frozen plasma. 36. Plasma is a pale yellow mixture of water, proteins and salts. 37. Plasma, which is 90 percent water, constitutes 55 percent of blood volume. 38. Healthy bone marrow makes a constant supply of red cells, plasma and platelets. 39. Car accident and blood loss victims can need transfusions of 50 pints or more of red blood cells. 40. Bone marrow transplant patients may need platelet donations from about 120 people and red blood cells from about 20 people. Can you be one of them? 41. Severe burn victims can need 20 units of platelets during their treatment. 42. Children being treated for cancer, premature infants and children having heart surgery need blood and platelets from donors of all types. 43. Anemic patients need blood transfusions to increase their iron levels. 44. Cancer, transplant and trauma patients, and patients undergoing open-heart surgery require platelet transfusions to survive. 45. Sickle cell disease is an inherited disease that affects more than 80,000 people in the United States, 98 percent of whom are of African descent. Some patients with complications from severe sickle cell disease receive blood transfusions every month -- up to 4 pints at a time. 46. 500,000: the number of Americans who donated blood in the days following the September 11 attacks. 47. Females receive 53 percent of blood transfusions; males receive 47 percent. 48. 94 percent of blood donors are also registered voters. 49. 60 percent of the U.S. population is eligible to donate blood -- only 5 percent do. 50. 17 percent of non-donors cite "never thought about it" as the main reason for not giving, while 15 percent say they're too busy. The #1 reason donors say they give is because they "want to help others." 51. After donating blood, you replace these red blood cells within four weeks. 52. It takes approximately eight weeks to restore the iron lost after donating. 53. Granulocytes, a type of white blood cell, roll along blood vessel walls in search of bacteria to eat. 54. White cells are the body's primary defense against infection. 55. There is no substitute for human blood. It cannot be duplicated in a laboratory. 56.
Since a pint is a pound, you lose a pound every time you donate blood.
