Donating blood: You can save a life

Donate blood.

Donate blood.
One person can donate 475ml (1 unit) of blood every 2 months, or 56 days. Your 1 donation can save the lives of up to 3 people.

Blood can’t be artificially manufactured and blood donation services such as the Western Cape Blood Service (WCBS) relies on voluntary blood donors and encourages all eligible donors to donate.

There's always a need for blood donors as approximately only 1.5% of the Western Cape’s population donates blood.

Donated blood is separated into red blood cells, plasma and platelets. Whole blood is only used in cases of severe blood loss during surgery, trauma or for exchange transfusion in infants.

  • Red blood cells: Can be used for patients who experience blood loss as a result of accidents, trauma, surgery or blood loss during childbirth.
  • Plasma: Is used as a source for clotting factors, replacement of blood volume and albumin, a protein used to treat severe shock and burns.
  • Platelets: Help blood clot and are used to treat patients with bone marrow production problems and in the treatment of leukaemia.

6 Reasons why you should donate blood

According to WCBS, there are many good reasons to donate blood which include:

1. Blood saves lives
Every unit of blood donated can be separated into 3 components and used to help improve and save the lives of up to 3 recipients.

2. There’s no substitute
There’s no known substitute for blood and it can’t be replicated due to its complexity.

3. Blood is in short supply
While 75% of our population are potential recipients, less than 1.5% are donors.

4. It’s a good cause
Giving doesn’t get much better than this.

5. You could be next
It's not a nice thing to consider, but the fact is that you, a close friend, or a family member could well be the next car accident victim or surgery candidate requiring a transfusion.

6. The process is safe and quick
Sterile, disposable equipment is always used, so there’s no risk of infection. The entire process takes just 30 minutes, after which you can resume your daily activities. Finally, you won’t even miss the one unit (475 ml) of blood donated, because it’s quickly reproduced and replaced by your body.

While donors from all blood groups and communities are important, there's a need for donors with blood types O to donate regularly as stocks of these are more vulnerable to shortfalls.  There's also a need for more black African people to become blood donors to reflect the ethnic diversity of patients.

You can donate blood if you:

  • are between 16 and 75 years old,
  • weigh at least 50kg,
  • are in good health,
  • lead a safe sexual lifestyle, and
  • love helping others.
