WebMar 27, 2014 · The chromogenic FVIII activity assay is based on a similar principle to the two-stage assay. In the first stage of the chromogenic assay, patient plasma (containing an unknown amount of functional FVIII) is added to a reaction mixture consisting of thrombin or prothrombin, FIXa, FX, calcium, and phospholipid. Factor assays are commonly undertaken when there is prolongation of the APTT or PT suggesting a deficiency of one or more clotting proteins. However, assays of other clotting factors e.g. FXIII or of the natural anticoagulants e.g. Protein C, Protein S and Antithrombin also constitute factor assays.
