A pre-publication article, Young G, Perry D, The International Prophylaxis Study Group (IPSG). Laboratory assay measurement of modified clotting factor concentrates: a review of the literature and recommendations for practice. J Thromb Haemostas pre-publication, 1-22-19 provides advice on how to measure extended half-life and B-domain-deleted factor concentrates VIII and IX. The article illustrates the wide variations in PTT-based one-stage clot-based assay results for the various new preparations related to the various reagent activators silica, kaolin, ellagic acid, or polyphenols. The writers show that the currently available chromogenic substrate factor VIII assays recover reasonably accurate results for all preparations. Chromogenic factor IX assays are approved for use in only a handful of locations but provide accurate measurement of factor IX concentrate therapy.
