Oklahoma City, OK – The Oklahoma Blood Institute needs the public's help.
Officials say the institute has a shortage of O-type blood -- both O positive and O negative.
The institute is asking anyone age 17 and older, who isn't affected by the icy weather conditions, to donate this week.
Donors can schedule an appointment at any OBI site by calling (866) 341-8728, or visit www.obi.org to see a list of blood drives and donor centers.
OBI provides blood used by most hospitals statewide.
