Right now, hospitals have a four-day reserve of blood. They are required to have a seven-day reserve at minimum.
Nassau County Executive Laura Curran will join county health officials to urge residents to donate blood and help replenish the critically low supplies.
For more information on where to donate or how to set up your own drive, visit www.nybloodcenter.org/blood or call 1-800-933-2566.
