accelerator factor

Thân thiện

A scientist adds an accelerator factor to a blood sample in a laboratory.

Definition

Noun: A specific coagulation factor (a substance in blood plasma) that is involved in the process of blood clotting, specifically in accelerating the conversion of prothrombin to thrombin.

Usage

This is a technical, medical term used primarily in hematology (the study of blood) and physiology. It refers to a precise biological agent essential for hemostasis (stopping bleeding).

Examples

• A deficiency in the accelerator factor can lead to a bleeding disorder.
• The laboratory test measured the activity of accelerator factor in the patient's plasma.
• Proaccelerin is another name for accelerator factor.

Advanced Usage

• Factor V: In modern medical terminology, "accelerator factor" is most commonly known and referred to as Factor V. This is its standard designation within the coagulation cascade.
• Labile factor: An older, synonymous term for this coagulation factor, referring to its instability when stored.

Variants and Related Words

• Proaccelerin: An alternative name for the inactive precursor form of accelerator factor.
• Accelerin: The activated form of accelerator factor (Factor Va).

Synonyms

• Factor V (the standard clinical term)
• Labile factor (historical term)
• Proaccelerin (precursor form)

Notes on Meaning

This term has a single, highly specific meaning in medical science. It does not have general or figurative uses outside the context of blood coagulation physiology.
