The South Bend Medical Foundation is asking for your help.
The blood bank is in critical need of blood.
Officials say they have less than a one day supply.
They are especially in need of O-positive, B-positive, A-negative and B-negative blood.
To donate, you must be at least 17 years old, be in good health and free of flu symptoms for at least 72 hours.
