AUSTIN, Texas -- We are Blood is in need of donations Memorial Weekend, as donations are low due to traveling for the holiday.

The organization is the sole provider of blood to Central Texas, serving 40 hospitals and medical facilities in a 10 county area.

The summertime, in general, is also a difficult time for donations because a large percentage of blood comes from drives held at high schools and colleges. We are Blood is asking for donations from all blood types, but is critically low on O Positive and O Negative.

They will be open on Memorial Day from 8 a.m. until 3 p.m. at the Austin North and Round Rock locations. For more information, visit www.weareblood.org.
