A semi-automated coagulation analyser is a laboratory instrument used to assess blood clotting functions by measuring various coagulation parameters, such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels. It combines automated features with manual intervention, allowing for precise control over testing while still reducing the amount of manual labor required. Typically used in clinical settings, this device plays a crucial role in diagnosing bleeding disorders, monitoring anticoagulant therapy, and ensuring proper blood coagulation during surgery. Its semi-automated nature offers a balance of efficiency, accuracy, and flexibility.
