What is Hemophilia severity?
Severe 0% – 1% factor level. About 80% of hemophilia sufferers are considered severe. Moderate 1% – 5% factor level. About 10% of hemophilia sufferers are considered moderate. Mild 5% – 50% factor level. About 10% of hemophilia sufferers are considered mild. Severity levels do not change during the course of the disorder. These levels are genetic and tend to run the same in a given family. “Normal” levels of clotting protein are 50 – 150%. Note: Severity levels are just a benchmark. Many people with hemophilia have bleeding patterns that reflect the severity level above or below the actual diagnosis. It is believed that this is caused by how well all the other components of the blood clotting cascade are working.
