Before you visit
Check the center's rules first.
Donation requirements and new-donor promotions vary by center. Use the official center link before you travel, especially when you need to confirm documents, eligibility, appointment availability or a current offer.
Confirm the address and official hours.
Read the center's current donor requirements.
Book through the official center page when it offers appointments.
Contact the center directly when a requirement is unclear.
HHS advises asking your center which health conditions or medications may prevent you from donating, getting plenty of rest the night before, drinking water or other caffeine-free drinks in the hours before your appointment, eating a healthy low-fat meal, and avoiding nicotine and alcohol before you donate. Expect to show documentation and pass a medical screening at the center.
