There are always bottlenecks in the blood supply in Germany – for example during the holiday season. How does blood donation work, who can donate and what advantages it has for donors.

A total of 15,000 blood donations are needed every day in Germany – to treat cancer patients, blood transfusions for diseases of the heart, stomach and intestines, complications during childbirth or to treat accident victims. According to the German Red Cross, it was difficult to cover the normal need for blood supplies during the Corona crisis. Blood donation is generally done in the summer. Therefore, on World Blood Donor Day, donations are once again demanded. The most important questions and answers about donating blood.

How willing are Germans to donate blood?

One in five Germans have already donated blood, according to a representative study conducted by digital insurance director Clark in collaboration with YouGov, in which about 1,000 people were interviewed. Among people who have never donated blood, there is a willingness to do so: 25 percent of 18-34-year-olds can imagine donating blood, among people over 55, the desire to donate blood for the first time drops to 14 percent. However, nearly every fifth person in Germany has never donated blood and cannot imagine doing so in the future.

For nearly half of Germans, the most important reason for donating blood is the desire to help the general public. Financial incentives only play a role at 18 percent.

Is it enough to donate blood?

According to the German Red Cross, only three percent of the population donate blood on a regular basis.

Every year, around 100,000 active blood donors across Germany cut off due to age or disease. On the other hand, the need is increasing among the elderly.

The blood supply runs out regularly especially in the summer, when many people are on vacation. In addition, the Corona pandemic has turned away many potential donors. At the beginning of the Corona crisis, blood donations decreased significantly in some places. But demand has also fallen because clinics have canceled many operations, and the situation has stabilized again in the meantime. But the number of interventions is now increasing, also due to many catch-ups. According to the blood donation service DRK, there are hardly any reserves.

Who can donate blood?

The temporary exception also applies after many vaccinations and trips abroad to malaria regions or countries at high risk of hepatitis. It is not possible to donate temporarily after major surgeries or when taking certain medications. Anyone with iron deficiency should not donate blood until iron reserves have been replenished.

After acupuncture treatments, unless it can be shown that they were performed aseptically, as well as piercings and tattoos, you should wait at least four months before the next donation in order to rule out infection with certainty. Waiting periods also apply to people whose sexual behavior may put them at greater risk of transmitting infectious diseases such as hepatitis or HIV.
