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.
Please check our Donating after Travelling tool to determine how long you need to wait before donating blood after returning from a country that has mosquito-borne infections including Zika and dengue viruses, and malaria.
Female donors exposed to Zika virus:
If you have a male sexual partner who recently returned from overseas AND in the last 3 months -
1) Has had Zika infection,
2) Has tested positive for Zika infection, or
3) Is awaiting test results for Zika infection:
You will need to wait 28 days from the last sexual contact with your partner before you can donate blood.
