Which type of Platelet collection involves a single donor?

The type of platelet collection that involves a single donor is apheresis. This procedure allows for the selective collection of specific blood components, such as platelets, from one donor while returning the remaining components, such as red blood cells and plasma, back to them.

During apheresis, blood is drawn from the donor and processed through a machine that separates the components based on their different densities. This not only maximizes the yield of platelets from the donor but also minimizes the need for multiple donations, making it an efficient and effective method for obtaining platelets.

In contrast, whole blood collection involves collecting all components of blood simultaneously from a donor without separation. Homologous refers to blood or blood components that are collected from one individual and transfused into another, which doesn’t pertain to the question about a single donor. Fractionation is the process of separating blood components after collection and does not relate specifically to platelet collection from a single donor.
