title: Half-life time and control frequency of vitamin K-dependent Coagulation factors. Theoretical considerations on the place of factor VII in the control of oral anticoagulation therapy.
abstract: A short review about the place of coagulation factor VII in the initial phase of blood coagulation is given. A theoretical model describing the relationship between the half-life times of vitamin K-dependent coagulation factors and the control frequency of oral anti-coagulation therapy is presented. The constraints that control frequency imposes on the type of determination to be carried out are discussed.
