Blood and Platelet Donation Qualifications

To ensure the safety of patients and donors, certain qualifications must be met before making a donation. Please note that units of blood and platelets collected at City of Hope are used only for City of Hope patients. We do not transfer or sell any blood products to other hospitals.
You can make an appointment online at or by calling 626-218-7171.

To make a donation:

  • If you would like to donate, you must be at least 17 years of age and weight at least 110 lbs. Donors age 16 may donate if they weigh a minimum of 120 lbs. and have a signed City of Hope Donor Center Parental Consent.
  • All donors must possess a government issued picture ID (e.g., a driver's license, passport, etc.). We also encourage you to have a healthy meal and be well hydrated (with non-caffeinated fluids) before donating.
  • Please note for platelet pheresis donors only: Do not take any ibuprofen, aspirin or aspirin-containing products 48 hours before your donation.


Patient-directed donations:

  • Directed donors must present the following information at the time of donation: the patient's name (as registered in the hospital), date of birth and/or medical record number.
  • A donor's blood type cannot be determined before donation. If the donor’s blood passes all tests, but is not the same blood type, it will automatically be released for use by other patients.
  • There is no credit system for directed units donated at local hospitals or any other collection agency.
  • Directed whole blood donations are reserved for the designated City of Hope patient for 35 days.
