The donation of plasma or "plasmapheresis" consists of extracting blood, separating the blood cells using a cell separator, retaining the plasma and returning the rest to the donor through the same route.
In the meal before donating plasma:
- Avoid eating a lot of fats, such as fried foods or heavy meals
- Avoid consuming sugary drinks or commercial fruit juices

Fats can be carried by the plasma and if you consume them in excess, your donation may not be able to be used.
During the donation
- Drink water even if you are not very thirsty.
- The donation lasts between 45 and 60 minutes, during which you can read, listen to music, or simply relax for a while.

- Avoid significant physical efforts, especially with the arm that was punctured, in the following 24 hours.
- If you are a smoker or plan to drink alcoholic beverages, wait 2 hours to do so.
- Drink plenty of liquids during the 24-48 hours following the donation.
