Every cellular diagnosis begins with precise formalin timing and steel blades. When preservation falters at the grossing bench, diagnostic clarity unravels before wax embedding begins.

Three stages of tissue preparation

Macroscopic dissection

Surgical specimens are measured, inked for surgical margins, and sectioned with scalpels under downdraft exhaust. Tissue slices are placed into labeled plastic cassettes for dehydration.

Four-micron ribbons

Embedded paraffin blocks meet razor-sharp rotary knives. Continuous tissue ribbons float onto heated water baths to eliminate micro-chatter before lifting onto charged glass slides.

Hematoxylin and eosin

Selective dyes bind chromatin in midnight blue while counterstains turn cytoplasm vivid eosin pink. Cellular architecture emerges in sharp microscopic detail under optical lenses.
