The Blood Bank of Hawaii is asking donors to step up as the organization faces a shortage.
The organization called for help on social media on Wednesday, saying, "We have only about a day's supply of the universal blood types O-positive and O-negative."
The blood bank provides life-saving blood to 18 hospitals statewide for a wide range of treatments, including accident victims and surgical procedures.
To schedule an appointment, call 848-4770 or schedule online.
