09 Histotechnology

The science of making tissue visible. Histotechnology covers the careful lab work that transforms tissue samples into stained slides, revealing structure, patterns, and clues used in diagnosis, research, and the development of new medicines. Fellow histotechnologists are invited to comment, question and suggest any corrections to the infographics and posts.

Protocol Transfer Is Not Copy and Paste

An IHC or histology protocol is the output of an entire laboratory environment, and when it travels, every hidden condition that shaped it stays behind unless someone deliberately carries it along.

The Wheel That Slices Gold

Oh, the wheel, how it turns! Round and round in the gold, with a block in its jaws and a secret to hold.

Diagnostic Staining and Biomarker Staining Are Not the Same Task

IHC tends to get discussed as one craft, measured against one idea of a good slide, even on benches that handle both kinds of work and feel the difference daily. The stain is not the deliverable. The answer is.

The Last Section: Tissue Stewardship and the Hidden Cost of Block Exhaustion

Block exhaustion is where decisions made long before the microtome, and long after the first slide is read, finally come due. The histotech just happens to be standing at the blade when the bill arrives.

The Hidden Judgment Work of Histotechs

A finished slide can make histotechnology look deceptively straightforward.
