The American Red Cross is calling out for type O blood.
The organization said Tuesday it is facing a critical shortage of type O, which is the blood type most needed by hospitals. The group said emergency rooms have less than a two-day supply.
To stimulate donations, the organization is offering to email a $5 Amazon gift card to eligible donors who give blood or platelets through June 10.
Blood drives are scheduled from noon to 5 p.m. Wednesday at Furnace Brook Wesleyan Church in Pittsford, 11 a.m. to 4 p.m. Saturday at the Diamond Run Mall and in several other Rutland County locations over the next two weeks. Blood drives can be found at redcrossblood.org.
