To rule out bleeding disorder
Thanks for your query.
By "ix" test, I assume that you are referring to Factor IX test.
Factor IX test is a blood test
that measures the activity of factor IX, one of the substances involved in blood clotting (coagulation) & is used to find the cause of too much bleeding in an individual.
It is considered as a screening test to detect the presence of, or rule out any bleeding disorder (like Hemophilia) in a child.
If possible, kindly attach the test reports along with a brief history of the symptoms your daughter is having.
It will be helpful for us to understand your concern better & formulate an appropriate management plan.
Hoping to hear from you soon.
