Why are blood donors always in demand?

While it would be amazing if we could store blood forever, the reality is every donation has a shelf life.

Your blood has a use-by-date 

Blood is a living tissue, and like all living things, it has a limited lifespan. Red blood cells, the main component of donated blood, can only be stored for up to 42 days under refrigeration. After this time, they lose their ability to carry oxygen effectively, making them unusable for transfusions.

The constant need for fresh blood 

Hospitals require a steady supply of fresh blood to treat patients. From surgeries and trauma cases to cancer treatments and chronic illnesses, the demand for blood never ends. Since we can’t stockpile blood for long periods, regular donations are crucial to ensure there’s always enough to meet the needs of patients.

Platelets and plasma

It’s not just red blood cells that have a short shelf life. Platelets, which help with blood clotting, last only about five days. Plasma can be frozen and stored for up to a year, but it’s often needed fresh for certain treatments.

You’re in demand 

By choosing to give blood, you’re playing a vital role in saving lives. Each donation can help multiple patients, but the clock starts ticking as soon as your blood is collected. That’s why regular donors are so important—they ensure a continuous supply of fresh blood for those in need.

Next time you donate, remember, being a donor is not just a one-time act of kindness. It’s part of a larger, ongoing effort to maintain our blood supply for those who need it most. So keep donating, and help us keep saving lives!
