Abstract

The utility of saving core biopsy specimens in sterile gel tubes was evaluated with 30 liver and 30 kidney core specimens obtained at open biopsy with an 18-gauge needle during autopsy. The core specimens were saved with one of three methods: gel tube, formalin swirl, or scalpel retrieval. The combined-organ mean time for the radiologist to save core specimens was not statistically significantly different with gel tubes (3.8 seconds) and the formalin-swirl method (4.5 seconds). Both of these methods, however, were significantly faster than the scalpel-retrieval method (11.2 seconds) (P < .001). The combined radiologist and cytotechnologist time was greatest with the gel tubes (35.1 seconds vs 14.7 and 21.2 seconds, respectively). Core specimens were broken with the formalin-swirl and scalpel-retrieval methods but not with the gel-tube method.
