apheresis

Definition

A blood-filtering procedure where specific components (platelets, plasma, or white blood cells) are separated and removed while the rest is returned to the donor. Think of it as a biological sorting hat, minus the Hogwarts drama.

Example Usage

The oncology patient required platelet apheresis to reduce their dangerously elevated platelet count before surgery.

Origin

From Greek 'aphairesis' meaning 'removal' or 'taking away'

Fun Fact

Donors undergoing apheresis can donate specific blood components more frequently than whole blood because their body replaces them faster.
