Special Stain, Steiner
Also known as: STEINER SS
Use
The Steiner special stain is a histochemical stain used to detect organisms—such as Helicobacter pylori and certain bacteria—in formalin-fixed, paraffin-embedded tissue specimens. It serves as a stain-and-return (technical) service for pathologic evaluation and does not itself provide interpretive clinical results, but supports diagnosis through visualization of microorganisms identified by morphology post-staining.

Limitations
Specimens must contain representative tissue; depleted or nonrepresentative specimens are unacceptable. Slides or blocks exposed to excessive heat or improper fixation may compromise stain quality. Frozen specimens are unacceptable. Only technical staining is provided, not diagnostic interpretation.
