==Biopsy bags==
==Biopsy wraps, bags and sponges==
Put the following types of specimens in these:
[[File:Biopsy wrap, biopsy sponge and biopsy bag.jpg|thumb|Items used for submitting specimens: (Biopsy) wrap, (biopsy) sponge, (tissue processing) cassette and (biopsy) bag.]]
*Tiny fragments that need to be poured out from their contianers.
Put the following types of specimens in '''bags''':
*Bloody specimens such as endometrial curettages or [[products of conception]]. For products of conception, chorionic villi may otherwise contaminate other specimens.
*'''Tiny''' specimens that need to be poured out from their containers.
*Friable tissue such as urinary bladder biopsies.
*'''Bloody''' specimens such as endometrial curettages or [[products of conception]]. For products of conception, chorionic villi may otherwise contaminate other specimens. Bloody specimens may stick to wraps, so generally avoid that situation.
*'''Friable''' tissue such as urinary bladder biopsies.
 
Put the following types of specimens in '''bags, wraps or sponges''':
*Other '''tiny''' specimens
*{{Comprehensive-begin}}Any important small piece of tissue, since specimens occasionally get lost from cassettes, and the absence of a biopsy bag in the cassette of such cases points towards a mistake made at gross processing.{{Comprehensive-end}}

Specimens must be fixed enough to be put on sponges.
