Extended Hemostasiogram (Coagulogram): D-Dimer, Thrombin Time, Prothrombin/INR, Fibrinogen, Antithrombin III, % Activity, APTT, etc.
The extended hemostasiogram is a comprehensive study of the blood clotting system, including assessment of coagulation, anticoagulant protection, and fibrinolysis.
Test composition includes:
• PT (Prothrombin Time) — assesses the extrinsic clotting pathway
• PI (Prothrombin Index) — clotting factor activity in %
• INR — standardized assessment, anticoagulant monitoring
• APTT — assesses the intrinsic and common clotting pathways
• Fibrinogen (standard and Clauss method) — concentration and functionality
• Thrombin time — final stage of coagulation
• Antithrombin III — main natural clotting inhibitor
• RFMC — fibrinolysis activity and fibrin breakdown products
• D-dimer — indicator of thrombosis and fibrinolysis
Mechanism of abnormalities: hemostasis disorders may be related to deficiency or dysfunction of clotting factors, decreased anticoagulant protection, increased activation of thrombosis or fibrinolysis.
Biomaterial: Venous blood (plasma/serum)
• Submit blood fasting
• Avoid alcohol for 24 hours
• Avoid physical exertion and stress 30 minutes before the test
Medications:
• If taking anticoagulants, antiplatelet agents, hormonal medications, or potent drugs, inform the doctor before the test.
Prescribed for:
• Suspected thrombosis or thromboembolism
• Tendency to bleeding or increased clotting
• Liver, kidney, heart, and vascular diseases
• Inflammatory and infectious processes
• Monitoring anticoagulant therapy
• Pregnancy with thrombophilia risk
• Before surgical procedures
Recommended for:
• Patients with thrombophilia and thrombosis
• People with cardiovascular diseases
• Pregnant women with complication risk
• Before surgery or after injuries
Reference values depend on the laboratory method and are indicated on the result form.
Abnormalities require physician consultation and comprehensive assessment.
Important — the extended hemostasiogram is assessed comprehensively; individual indicators do not provide a complete picture of hemostasis status.
If abnormalities are detected: general practitioner, hematologist, cardiologist.
