Factor XIIIa by Immunohistochemistry
Also known as: FAC 13 IHC
Use
This is a technical (stain and return) immunohistochemistry (IHC) service for detecting Factor XIIIa antigen in tissue or cell specimens. It is used to characterize or classify cellular morphology by identifying the presence of Factor XIIIa protein in formalin-fixed, paraffin‑embedded tissue or cell preparations, supporting histopathologic interpretation in diagnostic settings.
