What is leukodepletion, and why is it important?

Leukodepletion is the removal of white blood cells from donated blood. It is important because it reduces the risk of infections and reactions in patients receiving the blood.

How is blood separated into its components in the lab?

A centrifuge machine spins the blood, separating it into layers: plasma rises to the top, red blood cells settle at the bottom, and platelets remain in the middle.

How does a single blood donation benefit multiple patients?

One blood donation can save up to three lives because the separated components can be used for different patients and medical conditions.

What is the role of hospital transfusion laboratories?

Hospital transfusion laboratories request blood and components using an online ordering system and ensure that the right products are available for patients' needs.

What is the shelf life of different blood components?

Red blood cells can be stored for up to 35 days, platelets for up to seven days, and plasma can be stored for up to three years.

How are donors informed about the use of their blood?
