World Blood Donor Day

People who donate blood to patients save lives, and World Blood Donor Day was established in their honor. This day focuses on the importance of mutual assistance, responsiveness, and awareness about blood donation.

History

Blood donation has an ancient history and has been known since times when medicine and science were not yet well developed. The first experiments were conducted on animals, and the process was a success. The discovery of blood groups is credited to the outstanding scientist Karl Landsteiner. His groundbreaking work made efficient blood transfusion possible. World Blood Donor Day was first observed in 2005, with the date chosen to coincide with Landsteiner’s birthday on June 14.

Interesting Facts

Blood donation is crucial for the healthcare system.

1. Blood consists of cells: erythrocytes, platelets, and leukocytes, with plasma being the essential component.
2. To raise awareness, public organizations and volunteer associations organize events and distribute informational materials.
3. Blood can have a positive or negative Rh factor, reflecting the presence of a specific protein on red blood cells. A positive factor means compatibility with different types, while a negative factor means compatibility with identical types.
4. Blood has a shelf life: plasma can be frozen for a year, and red blood cells remain active for up to 42 days.
5. There are 8 blood types, with type O considered a universal donor type suitable for all others.

Every year, 5 million Americans require blood transfusions.
