    "description": "A preparation step used when a specimen contains bone or other calcified material that is too hard to slice on a microtome. The tissue is soaked in an acid or chelating solution until the mineral is dissolved and what remains can be cut into thin sections and stained. It is reported alongside the pathology examination it supports, not on its own, because it is extra laboratory work performed before the slides can be read.",
