Frequently Asked Questions (FAQ)

Commonly asked questions about blood donation:
Why can’t I give blood if I weigh less than 50kg?

The volume of blood we draw is in direct proportion to body mass. A smaller person has less blood. A donation of 480 ml is a far larger percentage of total blood volume for a small person. This places the donor at significant risk of adverse reactions post-donation.

What blood group is needed the most?

All blood types are vital to ensure sufficient blood stocks to meet the demand.
Group O Rh-negative blood can be transfused to anyone. These donors are called “Universal Donors” (but these people can only receive group O Rh-negative blood).
Adequate stocks of group O blood are vital.

Who are the safest donors?

Voluntary, non-remunerated (unpaid) donors who give blood regularly are the safest. Their primary motivation is to help injured or sick people and they want no reward other than knowing they have helped to save someone’s life.

What tests do you use?

Since the inception of our new risk model in October 2005, we run Nucleic acid Amplification Technology (NAT) tests on every unit of donated blood.

This is a very sensitive test which detects the presence of the HI-virus (HIV), Hepatitis B, Hepatitis C and syphilis in blood. However, there is still the danger of the window period which no test in the world can detect.

South Africa is the first country to implement NAT testing for individual blood donations at this scale.

Do you test blood at random?

No. Every unit of blood collected goes through the same stringent testing. It does not matter if it’s your first donation or if you are a regular donor, every donation of your blood is tested.

Can I donate blood for a family member?

Our rigorous blood donation and testing processes imply that the blood we collect from the population is quite safe. However, if you or a family member prefer to receive blood from a specific person you must discuss this option with your doctor, thereafter with our staff who will explain the risks, benefits and process involved.

Can I donate blood for myself?

A similar process would apply as explained above.
