What is whole blood?

Whole blood is the term used for blood that is drawn directly from a donor, containing all its natural components: red blood cells, white blood cells, platelets, and plasma. It is the most commonly donated type of blood and is vital for a wide range of medical needs. Whole blood is usually separated into its different components after donation, so that each patient receives only what they need most.

Why should I donate whole blood?

Every unit of whole blood can potentially save up to three lives. Hospitals rely on a steady supply of whole blood donations to treat patients who have suffered trauma, undergone surgery, or are living with conditions like anaemia, cancer, or blood disorders. It’s one of the easiest ways to make a powerful, lifesaving impact in your community.

How do you donate whole blood?

Whole blood donation is quick and simple:

  • After you fill in the donor questionnaire, we test your blood pressure and haemoglobin levels before you move to the donation bed.
  • A needle is placed in your arm and blood is collected into a sterile bag.
  • The entire process usually takes about 30 minutes including registration and refreshments.

Is whole blood donation safe?

Whole blood donation is a very safe process. All equipment used is sterile and used only once. Some donors may experience minor side effects such as light-headedness, bruising, or a slight discomfort at the needle site — but most people feel fine and return to their normal routine quickly. It’s important to eat beforehand and stay well-hydrated to help prevent these effects.

What does it take to become a whole blood donor?

  • You must be between 16 – 75 years old (first-time donors under 18 need parental consent).
  • You must weigh at least 50kg.
  • You need to be in general good health on the day of donation.
  • Your haemoglobin level should be within our acceptable range (measured at your donation).

You can donate whole blood every 56 days (8 weeks).
