[Current aspects on evaluation of assays of factor-VIII activity, factor-VIII associated protein and factor-VIII neutralizing antibody (author's transl)]. 1978

G Hintz

In evaluating factor-VIII activity it should be noted that regarding the remaining activity of deficient plasma a linear reference curve is achieved. In the standard population factor-VIII activity and factor-VIII associated protein are distributed approximately lognormally. Due to this distribution certain results have been gained for the optimal choice of localisation and dispersion measures. It is assumed that the proportions of neutralized factor-VIII activity in plasma are distributed according to Poisson. The applicability of the Poisson distribution was also proved for the free factor-VIII activity portion. Due to the Poisson distribution the antibody unit is clearly defined, thus eliminating a further discussion on the establishment of an arbitrary standardized antibody unit.

D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D001782	Blood Donors	Individuals supplying blood or blood components for transfer to histocompatible recipients.	Blood Donor,Donor, Blood,Donors, Blood
D005169	Factor VIII	Factor VIII of blood coagulation. Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin.
