The American Red Cross says there's an urgent need for blood donors.
The organization says donors with types O negative, B negative and A negative are especially needed.
The Red Cross says blood donations often decline during the summer months, particularly around summer holidays.
With school starting back up and summer activities coming to an end, the organization says there's still time for eligible donors to make a difference.
