clotting factor
A doctor explains the role of a clotting factor to a patient using a medical diagram.
Noun: A clotting factor is any of several specific proteins or substances present in blood plasma that are essential for the process of blood coagulation (clotting). When a blood vessel is injured, these factors activate in a complex sequence, ultimately leading to the formation of a fibrin clot to stop bleeding.
The term "clotting factor" is used primarily in medical and biological contexts to discuss the components of the blood coagulation cascade. It is often followed by a Roman numeral (e.g., Factor VIII) to specify a particular protein. - Example: A deficiency in a specific clotting factor, such as Factor VIII, can lead to a bleeding disorder like hemophilia. - Example: The doctor ordered tests to measure the levels of various clotting factors in the patient's blood.
- "Intrinsic/Extrinsic Pathway": Clotting factors are traditionally categorized based on which coagulation pathway they initiate. Factors like XII, XI, IX, and VIII are part of the intrinsic pathway, while Factor VII is part of the extrinsic pathway.
- "Factor Deficiency": This is a common medical term referring to a condition where a specific clotting factor is missing or dysfunctional.
- Example: Her clotting factor deficiency requires regular infusions of the missing protein.
- Coagulation Factor: A fully synonymous term for "clotting factor."
- Factor [Roman Numeral]: The standard way to refer to an individual clotting factor (e.g., Factor V, Factor X).
- Anticoagulant: (Noun) A substance that opposes or inhibits the action of clotting factors, preventing coagulation.
- Hemostasis: (Noun) The overall process of stopping bleeding, which involves blood vessels, platelets, and clotting factors.
- Coagulation factor
- Blood-clotting factor
- Procoagulant (in a general sense, though this can also refer to any substance that promotes clotting)
- Clotting cascade / Coagulation cascade: The sequential series of steps in which clotting factors activate one another.
- Example: Understanding the clotting cascade is fundamental to hematology.
- Clotting factor assay: A laboratory test to measure the activity level of a specific clotting factor.
- Clotting factor concentrate: A therapeutic product containing a purified clotting factor, used to treat deficiencies.
- Example: The hospital keeps a supply of clotting factor concentrate for emergency use.
