my 7 year old daughter had blood tests due to extremely heavy nose bleeds and unexplained bruising. I received a letter today from a consultant haematologist. It says that her Von Willebrand Activity test RiCoF was in normal range at 74%. However it is disproportional to the antigen level. Can you please tell me what this means.
Hello, Decrease only in on Hildebrand factor Rico (WWF:Rico) levels and normal on Hildebrand antigen (WWF:Ag) levels (WWF:Rico to WWF:Ag ratio Hope I have answered your query. Let me know if I can assist you further.
