Donor safety

When you’re giving blood with the Australian Red Cross Lifeblood, your comfort and safety are our top priorities.


Donating blood is a very safe process

Each donor’s blood is collected through a new, sterile needle that is used once and then discarded.

Most people have between 4.5 and 5L of blood in their body, so a blood donation is usually less than just 10 per cent of that. Your body restores the lost blood volume quickly. This is because, whether you give blood or not, your body constantly makes new blood to replace the old.

To protect your health we also have restrictions on how often you can donate.

Iron levels and blood donation

Blood donation removes red cells which contain the protein haemoglobin. A key component of haemoglobin is iron and so when you donate blood you lose some iron. In most cases this can be restored before the next donation. However, over time, iron levels may drop in some donors. This may lead to iron deficiency and/or low haemoglobin (anaemia). 

We check your haemoglobin before each donation to ensure that it is safe for you to donate and if your haemoglobin level is below the acceptable range you will not be able to give blood.

Your health and comfort

Most people feel fine during and after donating blood.

In fact, many donors find donating a relaxing break from the frantic pace of everyday life, as well as being personally fulfilling.

Some people do occasionally feel a small pinch when the needle goes in, but you shouldn’t feel any discomfort during the donation. A bit nervous? Read our tips.

Very rarely, some people feel unwell during or after a donation. Our expert team members closely monitor you while you’re in the centre, and record and follow-up all episodes where a donor feels uncomfortable or unwell. We use this information to keep you safe and to improve our procedures to make donating blood as safe and comfortable as possible for all of our donors.

You can reduce any chance of this by following these steps before and after you donate.


The Lifeblood tests all blood donations in Australia for a number of serious infections to protect the patients who receive donated blood.

We also test for some indicators of blood health, like iron levels and antibodies (proteins made by our immune system to help fight infections). Some antibodies can affect how patients’ bodies respond to donated blood when it’s transfused.

If our tests show anything abnormal, we contact you as soon as possible and provide counselling, referral and support.


As with all information held by the Lifeblood, the answers on your donor questionnaire and your test results are confidential. Test results are released only to the donor and agencies, such as to state government health departments, when required by law.
