Granulocyte transfusion
Granulocyte Transfusion
Granulocyte transfusion (pronunciation: gran-yuh-loh-syt trans-fyoo-zhuhn) is a medical procedure that involves the transfusion of granulocytes, a type of white blood cell, from a donor to a recipient.
Etymology
The term "granulocyte transfusion" is derived from the words "granulocyte", which refers to a type of white blood cell that contains granules, and "transfusion", which refers to the process of transferring something from one place to another. The term "granulocyte" is derived from the Latin "granulum", meaning "small grain", and the Greek "kytos", meaning "cell". The term "transfusion" is derived from the Latin "transfusio", meaning "pouring over".
Procedure
In a granulocyte transfusion, granulocytes are collected from a donor through a process called apheresis. The collected cells are then transfused into the recipient, usually a patient with a severe infection that has not responded to antibiotic treatment. The transfused granulocytes can help fight the infection by attacking and destroying the pathogens causing the disease.
