- International health guidelines state that all blood products must be tested for viruses such as HIV.
- Rare cases where blood or blood products have not been tested, such as a donated organ or tissue, could lead to HIV infection in the recipient if the donation has come from an HIV-positive individual.
- You have the right to ask your healthcare professional if a blood product has been tested for HIV or not.
- You cannot get HIV from donating blood as new, sterile and disposable needles are used.
Can HIV be transmitted through blood transfusions?
In the unlikely case that a person who is HIV-positive donates blood products which have not been tested, the person who receives the blood product is likely to develop an HIV infection too.
If you’re thinking about donating blood but are not sure about your HIV status, you can request an HIV test in advance of donating at your local clinic.
In order to prevent this, international health regulations require all blood products, such as organs or tissues, to be screened for a number of viral or bacterial contaminations before they are used.
This means that the transmission of HIV through blood products is very rare, but examples have occurred in some low-income countries which lack the equipment to test all blood.
How do I know if the blood transfusion/transplant I’m receiving is safe?
In most cases, it’s fine to assume the blood product you are receiving is safe. But if you are worried, it is your right to ask the healthcare professional if it has been tested for HIV or not.
Blood donors are asked a set of standard questions just before donating blood to help determine if they are in good health or if they have been at risk of HIV infection in the past.
Some groups of people who are considered more statistically at risk of HIV infection are not eligible to donate blood products in some countries - either for set time periods or for life. These groups include:
- Men who have sex with men
- Sex workers
- People who inject drugs
Although these rules may seem discriminatory, if you fall into one of these groups of people, tell a healthcare professional and they can advise you whether it’s safe to donate blood or not.
Other activities may also require you to postpone your blood donation, such as having a tattoo or body piercing or if you are living with a certain health condition.
If you want to know more about donor eligibility, check the guidelines in your country as they are different all over the world.
Can I get HIV from donating blood?
There is no chance of getting HIV from donating blood. New, disposable and sterile needles will be used to collect your blood, meaning there will be no blood from an HIV-positive person on the needle.
If you suspect that the needle your healthcare worker is using is not new or sterile then ask them to change the needle before agreeing to give blood.
