Why is hemophilia called Christmas disease?
It’s estimated that two-thirds of cases are inherited. The other cases are caused by spontaneous gene mutations that occur for unknown reasons during fetal development.

Why females are not affected by haemophilia?
“Growing up, we understood that men had hemophilia and women were “carriers.” Women passed along the X-linked gene, but did not actually get hemophilia because (it was believed) that the “good X chromosome” compensated for the X chromosome that carried hemophilia.

These disorders affect males more often than females because females have an additional X chromosome that acts as a “back-up.” Because males only have one X chromosome, any mutation in the factor VIII or IX gene will result in hemophilia.
What is included in a von Willebrand panel?
Von Willebrand factor testing includes VWF antigen, which measures the amount of VWF, and VWF activity (also known as Ristocetin Cofactor), which evaluates the function of VWF. Some laboratories may offer a panel that includes both of these tests along with a factor VIII activity test.
What is meant by a female carrier?

A clot is a lump of blood that the body produces to prevent excessive bleeding by sealing leaks in blood vessels caused by wounds, cuts, scratches, and other conditions.
