CHICAGO (CBS)– The American Red Cross needs your help.

They are in serious need of type-O blood donations.

There is a less than three-day supply of the blood, and if they don’t get donations soon patients may be impacted.

Type-O is the most rare blood type, just 7% of U.S. residents have it, so if you do, you’re encouraged to help out by donating.

Donors of all blood types especially types O positive and O negative are urged to make an appointment to give blood now using the Red Cross Blood Donor App, visiting RedCrossBlood.org, calling 1-800-RED CROSS (1-800-733-2767) or enabling the Blood Donor Skill on any Alexa Echo device.
