Blood donation is designed to protect donors and recipients. Donor eligibility checks include health questions, a brief physical exam (including hemoglobin or hematocrit), and confirmation of identity.
Safety measures
- Single-use sterile needles and collection bags are used for each donor.
- Trained staff monitor donors during and after donation.
- Donated blood is tested for infectious diseases before use.
Donor benefits
Many donors report a positive feeling from helping others. Some studies suggest small, short-term physiologic changes after donation; however, donation is generally safe for eligible donors. If you have medical concerns, consult your doctor before donating.
If you feel unwell after donating, contact the center that handled your donation or seek medical advice. This page is informational and not a substitute for professional medical guidance.
