How are bleeding disorders typically diagnosed?

Blood tests. One may be suspicious due to bleeding with brushing your teeth or after blood draws, easy bruising, or red spots on the skin. Family history, heavy periods, or excess bleeding with pregnancies may also be clues. The way to make a definite diagnosis is with blood tests, such as a pt, ptt, platelet count or platelet function (von willebrand's factor).
Chance. Most patients usually have problems with bleeding only after serious injury, trauma or surgery. In many cases, mild hemophilia is not diagnosed until an injury, surgery or tooth extraction results in prolonged bleeding. The first episode may not occur until adulthood. Women with mild hemophilia often experience menorrhagia, heavy menstrual periods, and can hemorrhage after childbirth.
