Most donated blood is processed into plasma, red cells and platelets, and has a shelf life of 35 days. Large amounts of plasma are needed to make special plasma protein concentrates.
About 470ml of blood is taken during the process, plus 15ml for test samples. That's about 7-8 per cent of the blood volume of an average adult. It is replaced by the body within 24 hours.
The Blood Service comes about every three months and, as well as the "casuals", there are always a large number of committed regulars. Whangārei consistently shows up as one of New Zealand's highest donor centres.
• The blood collection service will be at the ASB Lounge on January 3 from noon to 5pm and on January 4 from 9am to 5pm.
