Blood Components and Processing

This topic explores the fundamental principles and technical procedures involved in the preparation of blood components, a core competency in tertiary-level biomedical and transfusion science programs in Zambia and beyond. Students will learn about the controlled physical means used in component separation, including centrifugation, timing, and temperature management. The topic covers essential equipment such as refrigerated centrifuges, blast freezers, plasma extractors, and storage units. It details the stringent donor criteria, collection protocols (volume, time limits), and mandatory testing for transfusion-transmissible infections (TTIs) like HIV, Hepatitis B and C, and syphilis. Understanding these processes is critical for ensuring blood safety, quality assurance, and effective inventory management in clinical and blood bank settings, directly supporting the training of competent laboratory scientists and technologists for the Zambian healthcare system and the broader tertiary education framework.
