pints

of blood.

Your pints of blood are made up of...

trillion

red blood cells,

Blood Cells

billion

white blood cells,

White Blood Cells

...and

trillion

platelets.

White Blood Cells

To put that into perspective, there are 7.6 billion people on our entire planet.

That's a lot of cells - all working together to perform the essential functions that keep you alive and strong.

When you give blood, you would normally donate

470 ml

(or just less than a Grande at Starbucks)

…which is % of those pints of blood contained in your body, right now.

Your blood is regenerating all the time at an astonishing rate.

You create...

2 million

Blood Cells

new red blood cells every second to replace those that have reached the end of their 120 day lifespan.

After a donation, your body simply ramps up production to replace the deficit.

The volume (or the plasma) of your blood is fully replenished in just...

24-48 hours

The construction of red blood cells takes a little longer.

Blood Cell Replenishment

You can expect to have fully replenished yours in...

6-8 weeks

You could donate at least 3 pints per year.*

*Varies between male and female donors. Always check with your doctor how regularly you can donate blood.
