Cytopathology and More | FNA cytology: Rapid on-site evaluation—how practice varies
May 2014—Rapid on-site evaluation, or ROSE, is a service that pathologists and cytotechnologists commonly perform to check the cellular content and adequacy of fine-needle aspiration smears and biopsy touch imprints. ROSE can inform the operator of the need to obtain additional samples and, in this cost-conscious age, make it possible to avoid having to repeat the procedure. ROSE allows for preliminary diagnosis so that additional material can be requested for ancillary studies such as flow cytometry, microbiology cultures, or molecular studies.
