People with Type 1 vWD have low levels of vWF and may have low levels of factor VIII(8). Type is the most common form of vWD. This type is most often associated with mucosal bleeding.
In Type 2 vWD, the vWF does not work properly. Type 2 is divided into four different subtypes: 2A, 2B, 2M and 2N. Each sub-type has a different type of bleeding associated with it. Extra blood tests may be ordered to determine the sub-type. This helps the doctors know what medications work bet for the patient’s type of bleeding.
Type 3 vWD usually has no vWF and low levels of factor VIII(8). Type 3 is the most severe form of vWD. People with vWD can bleed into their joints and muscles or have more severe bleeding like someone with sever Hemophilia A or B.
