A semi-automated coagulation analyser is a laboratory device used to test blood coagulation parameters, such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels. It automates certain steps of the process, including result calculation and sample analysis, while still requiring manual intervention for tasks like sample preparation and reagent addition. This type of analyser is widely used in clinical settings for diagnosing bleeding disorders, monitoring patients on anticoagulant therapy, and assessing coagulation function. The semi-automated nature of the device provides a balance of efficiency, accuracy, and flexibility.
