Calretinin by Immunohistochemistry
Also known as: CALRET IHC
Use
This immunohistochemistry test (Calretinin by IHC) is intended as a stain-and-return technical service, providing identification of calretinin protein expression in tissue or cells. It supports histopathologic evaluation, notably in differential diagnosis scenarios such as mesothelial versus other cell types, aiding pathologists in tumor typing or cell lineage determination.
