“Every 2-to-3 seconds in this country, someone needs blood. And you never know when you or someone you love will be the one. We all expect blood to be available when we need it, but only a few of those who can give actually roll up their sleeves.  If you have O Negative blood, it’s time for you to get involved.” Asay said.

If you want to volunteer, you must be at least 16 years old, weigh at least 110 pounds and be in good health. Donors 16-17 must have signed permission from a parent or guardian.
