Usually, the amount of blood extracted is 0.5 liters. The blood is then examined, processed and used for medical, pharmaceutical and scientific purposes.

The best known form of blood donation is the full-blood donation. About half a liter of blood is extracted from a vein, usually in the crook of the elbow. This process takes about 5-10 minutes.
In addition, it is also possible to extract only individual components from the blood, e.g. platelets (platelets), erythrocytes (red blood cells) or blood plasma.

Anyone who is at least 18 years old, has a minimum weight of 50kg and has no health concerns may donate blood.

With a rest period of approximately 2 months between full-blood donations, men can donate a total of six times and women four times a year.
