Gulab Makwana: Complete Guide to Clotting Factors – Understanding the Coagulation System
Gulab Makwana, Medical Lab Technologist at University of Sindh, Jamshoro, Pakistan, shared a post on LinkedIn:
“Complete Guide to Clotting Factors: Understanding the Coagulation System
Blood clotting is a complex and highly coordinated process that helps prevent excessive bleeding after injury. Clotting factors work together in a cascade of reactions to form a stable blood clot and maintain hemostasis.
This comprehensive guide covers:
- Overview of the Coagulation System
- Intrinsic, Extrinsic and Common Pathways
- Functions of Clotting Factors I–XIII
- Vitamin K–Dependent Factors
- Role of Platelets in Hemostasis
- PT, aPTT, TT and Other Coagulation Tests
- Hemophilia A, B and C
- Clotting Factor Deficiencies
- Acquired Coagulation Disorders
- Clinical Interpretation and Diagnostic Pearls
Why are clotting factors important?
- Prevent excessive bleeding
- Maintain normal hemostasis
- Support wound healing
- Essential for surgical and trauma patients
- Help diagnose bleeding and thrombotic disorders
Disorders involving clotting factors can lead to serious bleeding conditions such as Hemophilia, Von Willebrand Disease, Disseminated Intravascular Coagulation (DIC), and Vitamin K deficiency–related bleeding.
Understanding coagulation pathways and laboratory tests is essential for medical laboratory professionals, clinicians, pathologists, hematologists, nurses, and medical students.
Know the factors. Understand the pathway. Save lives.
Can you name the clotting factor known as the ‘Christmas Factor’?
