Nonsevere Hemophilia A Profile

Clinical Use:

This profile is appropriate for the evaluation of individuals suspected of or previously identified as having nonsevere (mild or moderate) hemophilia A, in order to determine if there is a twofold discrepancy in the one stage and chromogenic factor VIII activities as has been described in discrepant hemophilia A. Evaluation for nonsevere hemophilia A using a one stage (clot-based) activity assay only may lead to missed diagnosis or misclassification of disease severity.
