Noun: - A specific coagulation factor in blood plasma: Plasma thromboplastin antecedent is a protein, specifically Factor XI, that plays a crucial role in the intrinsic pathway of the blood coagulation cascade. Its deficiency is a known cause of a hereditary bleeding disorder.
This term is used exclusively in specialized medical and biological contexts, particularly in hematology, pathology, and clinical diagnostics, to refer to this specific clotting factor or its associated condition. - The patient's prolonged activated partial thromboplastin time (aPTT) suggested a possible deficiency in plasma thromboplastin antecedent. - Hemophilia C is caused by a deficiency of plasma thromboplastin antecedent, or Factor XI.
- In diagnostic reporting: The term is used in laboratory findings and medical reports to specify the involved factor.
- The coagulation panel indicated significantly low levels of plasma thromboplastin antecedent.
- Factor XI: The modern and more common synonym for plasma thromboplastin antecedent.
- PTA deficiency: A shorthand term for the bleeding disorder resulting from a lack of this factor.
- Coagulation factor: The general category to which plasma thromboplastin antecedent belongs.
- Factor XI: The standard contemporary term.
- FXI: The common abbreviation used in medical shorthand.
- Intrinsic pathway: The part of the coagulation cascade where plasma thromboplastin antecedent (Factor XI) is activated.
- Hemophilia C: The clinical bleeding disorder associated with a deficiency of this factor.
- Coagulation cascade: The series of steps involving factors like plasma thromboplastin antecedent that lead to blood clot formation.
