### Definition of Factor x

1. Noun. Coagulation factor that is converted to an enzyme that converts prothrombin to thrombin in a reaction that depends on calcium ions and other coagulation factors.

Exact synonyms: Prothrombinase
Generic synonyms: Clotting Factor, Coagulation Factor

### Medical Definition of Factor x

1. Storage-stable glycoprotein blood coagulation factor that can be activated to factor xa by both the intrinsic and extrinsic pathways. A deficiency of factor x, sometimes called stuart-prower factor deficiency, may lead to a systemic coagulation disorder. Chemical name: Blood-coagulation factor X (12 Dec 1998)
