Stanford Blood Center officials report supplies of Type O blood and blood products are critically low. Donors are urgently needed for both O Positive and O Negative blood types. 

Blood donations tend to drop during summer months, which could further strain the already low supply. All community members are encouraged to donate and bolster supplies that serve local partner hospitals and meet the needs of local patients. A single pint of blood can save up to three lives.

Individuals can make a blood donation appointment online, call 888-723-7831 or simply walk in to one of the donation centers in Menlo Park, Campbell or Mountain View. 

There are certain requirements to donate blood. Donors must be at least 17 years old, weigh at least 110 pounds and be in good overall health. Donors can be 16 years old with written consent from a parent or legal guardian. It is also important to drink plenty of fluids and eat a good meal prior to donating blood.
