What is that
Factor 13 Deficiency?

 

[lee-usmle]

Factor XIII versus Factor XII

Oh yes there is
check this emedicine article

It's rare AR disease

Classical USMLE question is bleeding right after birth from umbilical stump

Don't confuse it with Hageman Factor XII, deficiency of which causes thrombotic tendency rather than bleeding

 

[matz]

it's quite simple
the question triggering factor XIII deficiency might be as follows:

an active bleeding while all coagulation tests (PT,PTT,INR,BT) are within normal range !
