Types of Blood Donations

Whether you give blood or platelets, your donation has a lifesaving impact for patients in your community.

Whole Blood

Giving whole blood is the most common blood donation. You can give whole blood at all our locations and drives.


“Whole blood” means your donation includes everything in your bloodstream: red blood cells, platelets and plasma.


Your donation can save up to three lives and is used for a wide range of patient care, including trauma, cancer treatments, caring for moms and their newborns, and more.

Fill Out Donor Doc: 5 - 10 minutes
Screening: 10 - 15 minutes
Donation: 15 - 20 minutes
How often you can donate: Every 56 days


Platelets are cells that help stop bleeding.

Platelet donation is an automated donation where your blood is passed through a device that takes out the platelet cells and returns the rest to you. You shouldn’t take aspirin or ibuprofen for two days before you donate, since they can make platelets less effective.

Most platelets have a shelf life of seven days, and they are constantly needed. Patients who have traumatic injuries need platelets, as well as those undergoing cancer treatments and transplants.

Donation time: Between 90-120 minutes
How often you can donate: Every 7 days, with a maximum of 24 times a year
Female donors: If you have had a child, you must be tested for human leukocyte antigens (HLA) before you can give platelets. The presence of HLA can cause a reaction in some patients. HLA testing is done with any other type of donation

Dual Red Blood Cell

Dual red cell donation means you give just red cells. Your blood passes through a device that takes out the red cells and returns all the other parts of your blood back to you.


More than 60% of blood transfusions are red blood cells only, and they are vital components for surgeries.


Male donors must weigh at least 130 pounds and be at least 5-foot-1. Female donors must weigh at least 150 pounds and be at least 5-foot-3.

Fill Out Donor Doc: 5 - 10 minutes
Screening: 10 - 15 minutes
Donation: 25 - 30 minutes
How often you can donate: Every 112 days
