On June 14, 2023, World Blood Donor Day will be celebrated again around the world. Officially proclaimed as an annual event by the World Health Assembly in 2005, the day celebrates voluntary blood donors around the world, provides a special occasion to thank blood donors, and promotes universal support for safe blood transfusions. It has become a key focus of action to achieve access. .

Life is in blood

Blood is the thick scarlet soup of proteins and cells that keeps us alive. A few nights in the emergency room will convince you that your body is just a giant bag of blood. In fact, in an average 70 liter human body, there is only 5 liters of blood, or 7% of his volume. Blood normally resides in the heart, blood vessels, sinusoids of the bone marrow, liver, and spleen. Of the average 5 liters of blood, only 2.25 liters, or 45%, are made up of cells. Red blood cells, white blood cells, and platelets are the forming components of blood. The rest is plasma, 91.5% (by weight) water and 8.5% solids (mainly albumin). Out of 2.25 μl cells, only 0.037 μl (1.6%) are white blood cells (Figure 1). 2). If the entire circulating white blood cell population were purified, it would fit in a coffee cup. The total amount of circulating platelets is even smaller, about 0.0065 L, or about 1 teaspoon. We explore the relationship between blood and all physiological patterns, as blood is the fluid that connects all body systems and the substance upon which all body cells depend.

Blood reveals much about the majesty of our creator and master craftsman, the irreducible complexity, and the state of health and disease of the human body. Each donation is a precious gift that saves lives, and repeated donations are key to building a safe and sustainable blood supply.

Blood services in many countries face the challenge of supplying adequate blood while ensuring quality and safety. Especially in low- and middle-income countries, the lack of access to safe blood and blood products affects all patients, including those requiring regular blood transfusions. One of WHO's strategies is to optimize the use of plasma obtained from whole blood donations and to improve patient access to life-saving plasma protein therapy by using low- and low-cost plasma to improve the availability and quality of human plasma. to help middle-income countries.
