United Blood Services says it's experiencing a critical shortage of O-negative blood on the Central Coast.
The blood bank is asking O-negative donors to donate blood as soon as possible.
O-negative is known as the universal blood type for red cells.
It's used in emergency situations when there is no time to determine a patient's blood type.
