    This is an international survey to understand the current practices and perspectives of hemophilia providers worldwide in diagnosing Women and Girls with Hemophilia A (WGwHA) in regards to using one stage assay (OSA) versus chromogenic assay (CSA).

    Purpose: The purpose of this survey is to collect data regarding whether hemophilia providers in different centers use OSA or CSA in diagnosing WGwHA, to assess various parameters for CSA including cost, availability and other challenges.

    Rationale: There is published literature that documents OSA:CSA discrepancies in males with mild to moderate hemophilia, and that patients with lower factor levels by CSA have more bleeding tendencies, leading to change in Hemophilia severity assignment and modification of treatment practices based on CSA values. As such literature evidence is sparse in WGwHA, collection of information on the global practices of Hemophilia providers in utilizing OSA versus CSA in diagnosing WGwHA and assessing the challenges with doing CSA for diagnosing WGwHA, will help to generate consensus recommendations and evidence-based guidelines for the future, as well as, future prospective studies in this unique patient population.
