What happens before the plasma donate?

First of all, your personal data will be recorded on the basis of your identity card or a blood donation card. You will receive a blood donation card after your first blood donation. A doctor measures before the actual plasma donate blood pressure, pulse, body temperature and the hemoglobin value. Prerequisites include a minimum of 13.5 grams per deciliter in males and 12.5 grams per decilitre in females. A completed blood donation questionnaire, which provides information on previous illnesses, medications and vaccines, is necessary. In addition, you must have donated at least once whole blood before your first plasma donation and weigh at least 50 kilograms.

Anyone whose health is safe can donate plasma. Immediately after surgery and vaccinations or taking antibiotics you should not donate plasma, but wait a few weeks. Even tattoos or piercings should be at least four months ago with a plasma donation.

In addition, there are permanent exclusion criteria for a plasma donation. HIV test, hepatitis B and hepatitis C test and evidence of other dangerous diseases must be negative.

How does a plasma donation work?

To avoid confusion, you will be prompted again by name and date of birth directly before the plasma donation. Then a suitable vein is punctured with a disposable needle and approximately 600 to 700 milliliters of blood are withdrawn in several cycles. The amount is mostly based on body weight.

With the help of so-called plasmapheresis, the plasma is now separated from the other blood components with a centrifuge or a filter and collected in a bag. The blood components and additional saline solution for fluid balance are donated to the donor after donating plasma again. This process takes about 45 minutes. Subsequently, the puncture needle is removed and a pressure dressing applied.

After donating blood plasma you can relax in special relaxation areas. For a quick recovery, it is helpful to drink a lot and eat protein-rich foods such as meat, fish, eggs and dairy products.
