It's almost summer and you are getting busy. The officials at the American Red Cross are hoping you'll take some time this summer to give the gift of life. Red Cross officials say the community blood supply has dropped to critically low levels for blood types O positive, O negative, B negative and A negative. Lisa Rhinehart is the executive director of the Yakima Red Cross office in Yakima who says overall, blood donations are down in the first five months of 2012, compared to the same period last year. As a result, there is almost half the amount of readily available blood in the red cross inventory at this point in time." to schedule an appointment go to redcrossblood.org or call 1-800 red cross (800-733-2767).
