Be a Blood Donor

Giving blood saves lives

Every 3 seconds someone needs blood, yet less than 5% of the population donates blood. That’s why we need your help. You could save someone's life.

Donors are needed on a daily basis for the thousands of patients who require blood transfusions. A single donation can help up to five patients. The need for blood always exceeds the available supply, so you can be sure that your donation is vital.

  • The Blood Donor Program

Through voluntary blood donation you can walk-in with no appointment and give blood that directly benefits the patients at Maimonides who are part of your community. In addition to general blood donations you can donate blood for your own surgery or for a family member, or replace blood that was used during a patient’s stay.


  • Autologous (Autogeneic) Blood Donor Program

You can donate your own blood for use during your surgery. Autogeneic or autologous transfusion is considered the safest method, because receiving your own blood minimizes risk of an allergic reaction. The process involves depositing one or more pints of your own blood, one to four weeks in advance of your scheduled surgery. Remember, at least 3 business days are needed to process the blood before transfusion.


  • Directed (Designated) Blood Donor Program

Your loved ones can donate blood for you. Donors come to the hospital at least five days prior to your surgery and designate blood for you. All donations matching the required blood type will be reserved for use in your surgery.


  • Replacement Blood Donation

Your family can pay it forward by making donations to replace blood that was utilized by you.

How do I prepare to make a donation?

Eat your regular meals. You do not need to fast and should not donate blood on an empty stomach. Bring photo identification, a list of any medications you take, and your reading glasses.


What happens when I donate blood?

There are four basic steps in the blood donation process which together take between 30-45 minutes.

  • Step 1. Registration – you will receive information about donating blood and a registration form for completion.

  • Step 2. Medical History – a medical screener will ask you about your health history in a private interview area, a mini physical will be performed that includes blood pressure, temperature and blood iron level measurements.

  • Step 3. Donation – you will be asked to sit in a reclining chair. Your arm will be sterilized with a swab and a sterile needle inserted into a vein – in the crook of your arm on the opposite side of your elbow. You will only feel a small pinch when the needle is inserted. The donation process rarely takes more than 10 minutes and the quanity of blood taken is about one pint.

  • Step 4. Refreshments – you will be invited to sit and enjoy refreshments. Most donors are able to resume their normal activities immediately. You are advised not to engage in strenuous activities for 24 hours after your donation.

Is donating blood safe?

Yes! Sterile, single use and disposable equipment is used for each donation and then safely discarded. It is not possible to acquire any disease from donating blood.


How often can I donate?

You may donate every 56 days, up to six times a year. Platelets can be donated through our TRIMA apheresis program up to 24 times a year with at least a three-day interval between donations.  



Different patients require different blood components - either platelets, red blood cells or plasma.  TRIMA, the technology behind our apheresis donor program, allows for the simultaneous and separate collection of platelets, red cell and plasma from whole blood.


How is a TRIMA Apheresis donation different from a whole blood donation?

Blood is drawn from your arm and channeled through continuous, sterile, single use tubing to an automated system.  TRIMA separates and collects the needed component(s), then safely returns remaining components to you. 


TRIMA Apheresis collections are safer for patients

By donating component(s) via an apheresis donation, you ensure that the recipients of your donations are receiving a full and consistent dose of whatever component they need.  You donate the quantity needed to give the maximum benefit of that component for the patient.  For example, an effective dose of platelets for a recipient requires an average of five to six units of platelets made from whole blood from separate donors.  The same effectiveness is achieved from one apheresis donor, which is safer and reduces a patient's exposure to multiple donors.

For information on apheresis donations, or to make an appointment, please contact the Blood Donor Center at 718-283-7657.



We can help if you supply the donors and a location. We conduct blood drives in our community and provide staff, medical supplies, advertising materials and refreshments. As an alternative, we also arrange transportation for small groups to come to our Blood Center to make donations.
