Blood Donation Guide: Who Can Donate, How It Works, and Why It Saves Lives

You've donated clothes, food, or money to help those in need. Now, consider saving lives through blood donation. Learn the eligibility criteria, find collection sites, and discover everything you need to know.

Why is blood donation so vital?

Each year, 1 million patients[1] receive care thanks to blood donations— that's 114 patients every hour. Despite this impact, the French Blood Establishment (EFS) faces ongoing shortages, particularly for O-, A-, B-, O+, A+, and B+ groups. Blood has a limited shelf life, making regular donations essential.

Experts estimate 10,000 donations are needed daily to treat patients with blood disorders, cancers (like leukemia, lymphoma, myeloma, myelodysplasia, and sickle cell disease), and hemorrhages.

I want to donate: What are the eligibility requirements?

To become a blood donor, meet these key criteria:

  • Be aged 18 to 70.
  • Weigh at least 50 kg.
  • Allow at least 8 weeks between donations.
  • Have no history of blood transfusions or organ transplants.
  • Be free from blood-transmissible bacteria, viruses, or parasites.
  • Have no sexually transmissible viral infections.
  • Not be pregnant.
  • Wait at least 6 months after giving birth.

Unsure about your eligibility? Complete the official questionnaire on the French Blood Establishment website.

The app that saves lives!

What precautions should I take?

On donation day, eat a light snack beforehand to prevent dizziness—avoid fasting. Skip fatty foods and alcohol in the hours prior. Expect a doctor's exam and health questionnaire to confirm no contraindications. Bring ID.

After donating, rest briefly under supervision, enjoy the provided snack, then head home. Skip sports, risky activities, or long drives that day.
