Donating Blood & Platelets

Donating Blood & Platelets

Blood donor

Giving just one pint of your blood can help save lives, and it only takes about an hour.

A healthy supply of blood and platelets is crucial for people with cancer, who need more blood products than people with any other type of illness. Because red blood cells can be stored for only 42 days — and platelets for just five days — we rely on donations from friends, family members, good citizens, and others to ensure there is enough for everyone.

How to Donate

To make an appointment to donate blood or platelets, please call us at 212-639-8177 or 212-639-7648.

We ask that all donors be in good health and at least 17 years old or under age 75 (or have parental or physician consent), weigh at least 110 pounds, and show picture identification.

If this is the first time that you’re donating blood and/or platelets, you may want to review our general donor guidelines and read our information about other specific requirements such as medicines that might affect your eligibility to be a donor and how frequently you are allowed to donate.

Answers to other common questions about the donation process, the difference between donating blood and platelets, and what happens to your donation are available in our FAQs section.

Feel free to call us at 212-639-8177 with any additional questions you may have.

Along with blood and platelets donated for use by all Memorial Sloan Kettering patients, we accept donations made for your own future use as well as directed donations for specific patients.
