Donation Requirements

  • Whole blood donors can donate every 56 days.

Travel Guidelines for Blood Donation

To protect the blood supply and to comply with regulations and safety guidelines, blood banks defer donors who have travelled to certain parts of the world. These rules are in place due to a potential travel-related risk of contracting an infection that may be transmitted through blood transfusion.  If you have questions or need more information, please call 1-888-8-BLOOD-8.

Recommendations Before and After Donating

  • Stay hydrated – drink 8-10 glasses of water a day leading up to your blood donation and avoid highly caffeinated energy drinks.
  • Get a good night’s sleep.
  • Eat a substantial meal within 3 hours before giving blood.
  • After giving blood, avoid participating in strenuous physical labor or athletic activities for 24 hours. Resume normal activities the next day.
  • PLATELET DONORS: No aspirin, or products containing aspirin, for at least 48 hours before your appointment.  Tylenol is acceptable.

On Medication?

The FDA has provided a list of restricted medications that are cause for deferral. In addition, anti-infective medications such as antibiotics and anti-virals may be cause for deferral. Most other medications are acceptable, including anti-depressants. 

Diabetics can give blood provided they don’t have complications associated with the disease.
