Plateletpheresis
Plateletpheresis
Plateletpheresis (pronounced: pla-te-let-fe-re-sis) is a medical procedure that involves the collection of platelets, a type of blood cell, from a donor's blood. This process is a type of apheresis, which is a broader term for the process of removing a specific component of the blood and returning the remaining components to the donor.
Etymology
The term "plateletpheresis" is derived from the Greek words "platelet", which refers to a small plate or disk, and "apheresis", which means to take away or remove.
Procedure
During plateletpheresis, blood is drawn from the donor and circulated through a machine. The machine separates the blood into its different components, and collects the platelets. The remaining blood components are then returned to the donor. This process allows for the collection of a large number of platelets, more than could be collected through a standard blood donation.
Uses
Plateletpheresis is often used to collect platelets for transfusion into patients who have low platelet counts, a condition known as thrombocytopenia. This can occur due to a variety of reasons, including certain types of cancer, chemotherapy, radiation therapy, or certain diseases of the immune system.
