Final answer:
The process in which a donor's own blood is removed and stored for future personal use is known as autologous blood donation.
Step-by-step explanation:
The process in which a donor's own blood is removed and stored in anticipation of a future need is known as autologous blood donation. This practice can be particularly useful for planned surgeries or in situations where a person's blood type is rare, making it difficult to find compatible donors. Unlike allogeneic blood donation, where blood is donated to the general blood supply for use by anyone in need, or directed blood donation, where blood is donated specifically for a known recipient, autologous donation ensures that the blood is available for the donor themselves. During the process of apheresis, certain components of the blood, such as platelets, are collected while the rest of the blood is returned to the donor's system. This method is different from autologous blood donation and is often used for different therapeutic and donation purposes.
