Usefulness of global tests of primary hemostasis in the initial screening of mild/moderate bleeding disorders for orienting towards von Willebrand disease or inherited platelet functions disorders
Thrombosis Research(2023)
Abstract
Minor bleeding manifestations are associated with several inherited hemorrhagic disorders collectively defined mild/moderate bleeding disorders (MMBD), including type 1 von Willebrand disease (VWD), platelet function disorders (PFD) and mild to moderate clotting factor deficiencies [ [1] Rodeghiero F. Pabinger I. Ragni M. Abdul-Kadir R. Berntorp E. Blanchette V. Bodó I. Casini A. Gresele P. Lassila R. Leebeek F. Lillicrap D. Mezzano D. Noris P. Srivastava A. Tosetto A. Windyga J. Zieger B. Makris M. Key N. Fundamentals for a systematic approach to mild and moderate inherited bleeding disorders: an EHA consensus report. Hemasphere. 2019; 3e286 Crossref PubMed Scopus (46) Google Scholar ]. The differentiation of these patients from hemostatically normal subjects is a difficult task and requires a careful clinical evaluation, including the application of standardized bleeding assessment tools (BAT) and the performance of some initial laboratory screening tests [ [2] Gresele P.

Haemost. 2015; 13: 314-322 Abstract Full Text Full Text PDF PubMed Scopus (202) Google Scholar ]. Among the latter, methods measuring the overall haemostatic potential of whole blood, like the skin bleeding time (BT) and the PFA-100®, are still used for suspected mucocutaneous MMBD [ [3] Gresele P.
