Safer blood has come from pairing scientific progress with a broader, more inclusive donor community in South Africa. Individual Donor Nucleic Acid Testing (ID-NAT), introduced nationally in 2005, changed how donated blood is screened; 21 years on, every donation still depends on someone choosing to give.

A difficult chapter that changed blood safety

The history of blood donation in South Africa includes hard questions as well as important breakthroughs. During the late 1990s and early 2000s, the HIV pandemic presented an urgent challenge to blood safety. SANBS had to manage the risk of infection through transfusion while working with stakeholders on improved testing approaches.

Some of the risk-management policies used at the time relied on race in decisions about donor collection and the use of particular blood products. That approach drew significant concern, including over the exclusion of Black donors and limits affecting the use of products from some Black donors. It raised a fundamental question: could the blood supply be protected through testing each donation, rather than making assumptions about risk based on a donor’s race?

In 2004, SANBS engaged with the National Department of Health and obtained approval to implement ID-NAT. In October 2005, it introduced a new donor-risk management model supported by individual-donation testing, moving away from race-based collection and utilisation policies. South Africa became the first country to introduce NAT testing for individual donations at national scale.

That change matters for more than its technical achievement. It marked a shift towards assessing each donation through laboratory evidence, while giving more people the opportunity to participate in a shared, voluntary service.

What ID-NAT does behind the scenes

A blood donation goes through a journey before it can be used for a transfusion. ID-NAT is one part of that journey: it looks for genetic material from HIV, hepatitis B, and hepatitis C in each individual donation. By detecting certain infections earlier than some other testing methods, it helps shorten the window period in which an infection may be present but not yet detectable through other tests.

No screening system can make risk disappear entirely. ID-NAT is one layer in a broader safety process that includes donor selection, honest answers to health and lifestyle questions, clinical checks, and laboratory testing. Donors are asked to answer candidly because screening works best when the information supplied is accurate as well as the science being used.

The process is a useful reminder that blood safety is a chain. Testing is essential, but so are the donor who gives honestly, the staff member who assesses the donation, and the systems that keep blood products traceable and available for patients.

A wider donor community strengthens the service

The impact of the move to individual-donation testing can also be seen in who is able to take part. According to SANBS, Black donors made up 4% of its donor base in 2005; by 2026, they accounted for almost 60% of the total donor base. A safer system should protect patients while enabling participation across South Africa’s communities. This shift shows how changes in policy and technology can help bring more people into a life-saving national service.

A larger, more representative donor community is important in a country as diverse as South Africa. Patients need compatible blood, and blood groups and other inherited characteristics vary among people. A broad donor base helps the service meet everyday demand and supports access to appropriately matched products. It also makes the act of giving feel less like a contribution from a small group and more like what it is: a shared responsibility.

The human story behind every unit

The SANBS documentary Why Blood Matters focuses on the people connected by donation: donors, recipients, and families whose lives are changed by transfusion. Its human stories sit alongside the scientific story of ID-NAT. One helps us see what a donation can mean to a person; the other shows the unseen work that takes place before donated blood is released for patient care.

Blood is needed for more than emergencies. Patients may rely on transfusions during surgery, childbirth complications, cancer treatment, and other serious illnesses. These needs do not pause when the calendar gets busy or when people leave the city for the holidays. Red blood cells also have a limited shelf life, so the supply has to be replenished continuously; a successful campaign today cannot replace regular donations over the months that follow.

That is why a call for blood donation is never just about a number on a stock report. As the holiday season approachers SANBS reported stocks below its five-day minimum target. They need around 3,500 units each day to meet demand. Group O is particularly important in emergencies where there may be little time to establish a patient’s blood group.

Blood donation in South Africa: what to expect

For a first-time donor, the process is structured and supported. You’ll complete a questionnaire about your medical history and lifestyle, speak privately with a staff member, and have your pulse, blood pressure, and haemoglobin checked. If you’re eligible on the day, a whole-blood donation is about 450 ml. The donation itself is only one part of the visit; allow time for the assessment and a short rest afterwards.

SANBS’s general requirements include being between 16 and 75 years old for first-time donors, weighing at least 50 kg, being in good health, and having eaten within four hours of donating. Whole-blood donors need to wait at least 56 days between donations. Some health conditions, medicines, recent procedures, travel, or other circumstances may mean a temporary deferral. A deferral is a safety measure, not a judgement; check the current guidance with SANBS or its donor staff if you’re unsure.

If you’re nervous about needles, tell the staff. You can ask what will happen, take a moment before starting, and stay seated afterwards. The equipment is sterile and single-use, and trained staff are there to guide you through the process. First-time nerves are common; you don’t need to arrive as an expert donor.

Make your next donation count

Technology has helped make blood donation safer, and wider participation has helped make the donor community stronger. But neither can substitute for a steady flow of willing donors. The story of safer blood is still being written each time an eligible person gives, answers honestly, and returns when they’re able.

Give Blood. Give A Tomorrow.

If you’re eligible, make a plan to donate instead of waiting for a quieter week that may never arrive. Contact SANBS on 0800 11 90 31 or visit sanbs.org.za to check your eligibility and find a donor centre or mobile blood drive near you. If you’ve donated before, consider returning; if you’ve never donated, ask the team what to expect. Every donation helps keep blood available for the patients who need it.

FAQs about blood donation in South Africa

Who can donate blood in South Africa?

SANBS’s general criteria say first-time donors should be aged 16 to 75, weigh at least 50 kg, be in good health, and consider their blood safe for transfusion. You’ll also need to meet health checks on the day. Staff make the final decision, so use the SANBS eligibility information or ask a donor centre if a particular circumstance applies to you.

How often can I donate whole blood?

SANBS advises that eligible donors can give whole blood every 56 days. The timing may differ for plasma or platelet donations, and the team will tell you when you’re next able to donate.

How long does donating blood take?

SANBS says the donation process takes about 30 minutes, though your full visit will also include registration, a questionnaire, health checks, and a short rest afterwards. Set aside extra time, especially for your first visit.

Is donated blood tested for HIV and hepatitis?

Yes. SANBS says every donation is tested, including with nucleic acid testing for HIV, hepatitis B, and hepatitis C. Testing is one part of a wider safety system and does not remove the need for honest answers during donor screening.

What if I’m temporarily deferred?

A temporary deferral means you need to wait for a specified period before donating, often because of a health-related factor. Deferral periods depend on the reason. Ask SANBS staff for guidance about when you can return; don’t assume that a delay means you can never donate.

Where can I donate blood in South Africa?

SANBS operates donor centres and mobile blood drives. Call 0800 11 90 31 or visit sanbs.org.za to find a location and check current donation information before you go.
