Routine follow-up is appropriate for reviewing preventive treatment, new bruising patterns, ongoing joint discomfort, menstrual bleeding, dental planning or an upcoming procedure.
Arrange the procedure with the hemophilia team in advance rather than waiting until the day.
Every sign above is quoted from the sofidex article on Hemophilia A. If you are not sure, err upward — it is always reasonable to be checked.
