The term "factor IX" (pronounced "factor nine") refers to a specific protein in the blood that is important for blood clotting. When someone has a deficiency or absence of this factor, it can lead to a condition called hemophilia B, which makes it difficult for their blood to clot properly. This means that people with hemophilia B may bleed more easily and take longer to stop bleeding.
