When donating, you will give around 470mL of blood. This is about 7% - 8% of the blood volume of an average adult, or 1.5 cans of soft drink, plus 15mL for test samples.
Malaria and Tropical Arbovirus infections (which include Chikungunya, Dengue and Zika), are mosquito-borne infections which can be transmitted by blood transfusion. Trypanosoma Cruzi (Chagas' disease) is an insect-borne infection found in poor quality housing in some South and Central American countries.
When can I donate?
Most people who travel outside New Zealand are still able to donate blood when they return. However, travel to an area where there is a risk of exposure to certain diseases can result in symptomless infection(s) that can be transmitted through blood transfusion.
