A semi-automated coagulation analyser is a laboratory device designed to measure various blood coagulation parameters, such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels. It combines automation with manual steps, allowing for faster and more accurate results compared to traditional manual methods. While the analyser automates the process of reading and calculating test results, some aspects, like sample preparation and reagent handling, require manual input. This system is widely used in clinical settings for monitoring coagulation disorders, assessing bleeding risks, and managing anticoagulant therapy, offering efficiency and flexibility in laboratory diagnostics.
