What is factor XIII?

Factor XIII (thirteen) is a naturally occurring protein within the blood that assists the blood in making clots. The absence of factors that clot can lead to bleeding that is not controlled since the blood does not effectively clot. Factor XIII functions by temporarily raising the levels of these factors in the blood, which aids in the process of clotting. In fact, factor XIII can be used to reduce bleeding episodes in patients suffering from an inherited bleeding disorder caused by a lack or deficiency of factor XIII. Factor XIII cannot treat bleeding that has already started. Factor XIII could be utilized for other purposes not mentioned in this guideline.
