Use

This immunohistochemistry stain detects chymotrypsin in formalin-fixed, paraffin‑embedded tissue sections or cell blocks. It is intended as a technical “stain and return” service—enabling pathologic assessment using ARUP’s immunohistochemistry stain, performed in a CLIA‑certified lab for clinical purposes, with results returned to the submitting laboratory or institution. It has not been cleared or approved by the FDA and is offered as a laboratory‑developed test under CLIA regulations.
