What does the term “coagulation” primarily refer to in a medical context?

In a medical context, the term “coagulation” primarily refers to the formation of blood clots. This process is essential for hemostasis, which is the stopping of bleeding when there is an injury to a blood vessel. Coagulation involves a complex series of biochemical reactions leading to the conversion of fibrinogen, a soluble plasma protein, into fibrin, an insoluble protein that forms the meshwork of a blood clot. This process prevents excessive blood loss and facilitates wound healing by creating a stable environment for tissue repair.

Understanding coagulation is critical in various medical situations, such as surgeries, trauma care, and managing conditions that affect clotting, such as hemophilia or thrombosis. The study of coagulation pathways and assessment through tests like the prothrombin time (PT) or activated partial thromboplastin time (aPTT) helps healthcare professionals monitor anticoagulant therapy and diagnose coagulation disorders.
