World Blood Donor Day is observed annually on June 14, and commemorates the birth of Dr. Karl Landsteiner, whose research identified the main blood groups: type A, type B, type AB and type O, as well as the Rh-factor in blood. Blood providers worldwide mark World Blood Donor Day by raising awareness of the need for safe blood and blood products and by thanking volunteer donors for providing a lifesaving resource in their communities.

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!
