People with O-Negative blood are being urged to donate by the Blood Service, as blood supplies drop to low levels.
Regular donors who are suffering from cold and flu symptoms are unable to donate, leading to a decline in supply, along with an increased demand for O Negative blood.
Spokesman Shaun Inguanzo said the Blood Service needs an extra 4,500 O-Negative donors to give blood before the end of July to increase supply.
“O-Negative is a universal blood type that can be used in an emergency situation where the patient’s blood type is unknown,” he said
“With one in three of us needing donated blood in our lifetime, the life you save could be that of a friend or family member.
“The number of people suffering cold and flu symptoms greatly impacts the number of regular donors who are able to give.
“We need others to take the place of those who will be unable to answer our call.”
If you are suffering from cold and flu symptoms, you are required to wait at least seven days after making a full recovery before giving blood.
