O Negative

The Universal Donor

Type O-Negative donors are universal donors. This means that their red blood cells can be transfused to any patient, regardless of the recipient’s blood type. In the case of an emergency, doctors often do not have time to determine the blood type of the patient and depend on Type O blood for trauma patients and accident victims.

Quick Facts

7% of the population is type O-.
O- is the highest in-demand blood type because anyone can receive O- red blood cells, although O- plasma can only be transfused to another type O.
Type O- red cells can be used for any patient but are especially needed for emergencies, for babies, and for those with weakened immune systems.
Preferred donation methods: double red blood cell and whole blood.
Doctors depend on type O blood for trauma patients and accident victims.
Although anyone can receive O- blood cells, type O- can only receive type O- blood.

Blood Types Needed

Many variables can impact our blood inventories such as weather, holidays or tragic events. Every day, patients who need blood are in crisis and you can help by volunteering to donate. Less than 10% of the population gives blood, so donors that give on a regular basis are important to meet these needs. Book an appointment today!
