Some sources of error in the one-stage assay of factor VIII. 1978

S Elödi, and K Váradi, and S R Hollán

The error of the one-stage assay of factor VIII activity is determined by the quality of reference and substrate (factor VIII-deficient) plasmas, as well as by the accuracy of dilution and clot observation time. Storage of the fresh normal plasma used as reference and/or of the substrate plasma for 2--3 h at 0 degrees C may cause considerable errors, which can be eliminated by the immediate use of plasma or by the determination of an appropriate correction factor. With all precautions taken into account the average error of the assay in our hands is 20%.

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.
