Becoming a Blood Donor

WCBS needs to collect around 700 units of blood every single day to support patients across the Western Cape. To do this safely, we try to maintain a five‑day blood stock at all times. Blood is needed far beyond emergencies — it is essential for surgeries, cancer treatments, chronic illnesses, premature babies, and severe infections.

One blood donation can save up to three lives, because each unit of blood is separated into different components used for different patients.

There are more than 7.6 million people living in the Western Cape, but only 66,780 are active donors. To stay sustainable, at least 1% of the population needs to donate blood regularly.

Can I donate blood?

You can donate if:

  • You are between 16 and 75 years old (first‑time donors must be 16–75).
  • You weigh at least 50kg for whole blood or 55kg for plasma donation.
  • You are medically healthy.
  • You live a safe sexual lifestyle.
  • You are committed to helping others.

What to Do Before Blood Donation

  • Make sure you meet the donor criteria.
  • Eat a good meal 3–4 hours before donating.
  • Drink plenty of water.
  • Find your closest blood donation clinic.

What to Expect at a Blood Donation Clinic

  • Complete a confidential donor questionnaire.
  • We verify your details and check your haemoglobin levels with a quick finger‑prick test.
  • A nurse will conduct a private medical screening.
  • You will then donate one unit of blood — about 475ml.
  • Afterwards, enjoy juice and cookies.
  • The entire visit takes around 30 minutes. You can donate every 56 days.

What to Do After Blood Donation:

  • Keep the plaster on for 6 hours.
  • Avoid heavy lifting with your donation arm.
