ST Genesia

ST Genesia

ST Genesia is an advanced diagnostic system used in the field of hemostasis to assess the risk of thrombosis and bleeding in patients. It is a fully automated analyzer that provides comprehensive insights into the coagulation process by measuring thrombin generation. This system is particularly useful in clinical settings for evaluating patients with clotting disorders, monitoring anticoagulant therapy, and conducting research in hemostasis.

Overview

The ST Genesia system is designed to perform thrombin generation assays (TGAs), which are crucial for understanding the dynamics of blood coagulation. Unlike traditional coagulation tests that measure the time it takes for a clot to form, thrombin generation assays provide a more detailed picture by quantifying the amount of thrombin produced over time. This allows for a better assessment of both procoagulant and anticoagulant pathways.

Technology

The ST Genesia utilizes a fluorogenic substrate that releases a fluorescent signal upon cleavage by thrombin. The intensity of the fluorescence is directly proportional to the amount of thrombin generated. The system is equipped with a sensitive detector that measures the fluorescence in real-time, allowing for the construction of a thrombin generation curve.

Components

• Analyzer: The core component of the ST Genesia system, responsible for processing samples and measuring thrombin generation.
• Reagents: Specialized reagents are used to initiate the coagulation cascade and to provide the fluorogenic substrate.
• Software: The system includes sophisticated software for data analysis, enabling the calculation of key parameters such as lag time, peak thrombin, and endogenous thrombin potential (ETP).

Clinical Applications

ST Genesia is used in various clinical scenarios, including:

• Diagnosis of Hemostatic Disorders: It helps in diagnosing conditions like hemophilia, von Willebrand disease, and other bleeding disorders.
• Monitoring Anticoagulant Therapy: The system is used to monitor patients on anticoagulant drugs such as warfarin, direct oral anticoagulants (DOACs), and heparin.
• Research: It is a valuable tool in research settings for studying the mechanisms of coagulation and the effects of new anticoagulant drugs.

Advantages

• Comprehensive Analysis: Provides a detailed assessment of the coagulation process beyond what is possible with traditional tests like PT and aPTT.
• Automation: Fully automated, reducing the potential for human error and increasing throughput.
• Standardization: Offers standardized protocols and reagents, ensuring consistent and reliable results.

Limitations

• Cost: The system and its reagents can be expensive, which may limit its use in some settings.
• Complexity: Requires specialized training to operate and interpret results.
