Normal Haemostatic Mechanisms

This topic provides a detailed examination of the physiological process of haemostasis, encompassing the vascular, platelet, and coagulation phases. Tertiary students will study the intricate coagulation cascade, including intrinsic, extrinsic, and common pathways, and the roles of all coagulation factors. The content is fundamental for understanding how the body prevents blood loss and maintains vascular integrity. For university and college learners in Zambia, this forms the basis for diagnosing coagulopathies like hemophilia and DIC. Mastery of this topic is essential for passing hematology examinations and for practical application in clinical laboratories, enabling students to interpret coagulation screening tests such as PT, APTT, and thrombin time accurately, a core competency in tertiary medical laboratory education.
