Who Can Donate Blood? Common Myths vs Facts

Think you’re not eligible to donate blood? You’re not alone. Thousands of people rule themselves out as donors based on misinformation—yet the truth is, most healthy adults can donate safely.

This June, during National Blood Donor Month, Affinity Health, a leading provider of high-quality health cover, is setting the record straight by busting the most common myths around blood donation.

The South African National Blood Service (SANBS) reports that fewer than 1% of South Africans are active blood donors, even though every unit of donated blood can potentially save up to three lives. Blood is needed not just for emergencies and surgeries but for patients with cancer, chronic conditions, childbirth complications, and trauma cases.

“There are so many myths out there that stop people from donating,” says Murray Hewlett, CEO of Affinity Health.

“People think they’re too old, too thin, or can’t donate if they’re on chronic meds. But the criteria are far more inclusive than people realise. If you’re healthy, you’re probably eligible.”

It’s time to separate fact from fiction. Here’s what you need to know.

MYTH: You can’t donate blood if you have tattoos or piercings.

FACT: You can donate blood if your tattoo or piercing was done with sterile equipment and it’s been at least three months. SANBS requires a short waiting period to reduce infection risks, but after that, you’re good to go.

MYTH: You’re too old to donate.

FACT: If you’re between 16 and 75, weigh more than 50kg, and are in good health, you’re eligible. First-time donors need to be under 65, but regular donors can continue beyond 75 with a doctor’s approval.

MYTH: Taking chronic medication disqualifies you.

FACT: Many people on treatment for conditions such as high blood pressure, depression, or even asthma can still donate. It depends on your medication and how stable your condition is—always speak to the SANBS or your GP.

MYTH: It takes too long and is painful.

FACT: The donation itself takes only 10 minutes. The entire process, including registration and a snack afterwards, lasts approximately 30 to 40 minutes. Most people say the discomfort is no worse than a quick pinch.

MYTH: Only people with a rare blood type should donate.

FACT: All blood types are needed. O-negative blood is universal and in high demand, but people with A, B, or AB blood types also provide lifesaving help for patients who match.

Despite these facts, donation rates remain low, especially among younger people. Cultural beliefs, lack of access, and fear of needles contribute to the hesitancy. Yet trauma-related injuries from car accidents, violence, and childbirth complications mean that hospitals regularly face blood shortages, putting lives at risk.

If you’re unsure whether you’re eligible to donate, the SANBS website offers a quick online quiz and helpful info. You can also speak to your GP or local clinic for advice. Most major shopping malls, workplaces, and universities also host regular blood drives, so donating is more convenient than ever.

Conclusion

Donating blood is one of the simplest yet most powerful ways to save lives, and chances are, you’re more eligible than you think. By busting common myths and understanding the facts, more people can step forward and make a difference. Whether you’re donating for the first time or are a long-time donor, your contribution matters. Affinity Health’s Day-to-Day Plan gives you access to healthcare professionals who can guide you on whether you’re fit to donate, manage any chronic conditions, and ensure your health stays on track before and after donation.
