The eROSE Device

AMCYT aims to provide rapid onsite evaluation (ROSE) service to all fine needle aspiration (FNA) providers. Through our state-of-the-art eROSE device, we hope to solve the unmet need for ROSE.


About ROSE


• Rapid onsite evaluation (ROSE) is an adequacy procedure that mitigates sampling error during a fine       

   needle aspiration (FNA) biopsy.

• Involves smearing of the tissue sample into a glass slide, staining, and real time microscopic evaluation

• Proven to improve the sensitivity and diagnostic yield of FNA​

• Assists further diagnostic triage (assess whether extra material is needed, decide how to preserve material for

   further ancillary studies)​

• Reduces the need for additional sampling with a lower risk of procedure complications

Unmeet need for ROSE


• 20-25% of FNA biopsies are insufficient for diagnosis due to lack of ROSE. ​

Large medical facilities are forced to staff pathologists during routine biopsy procedures to       perform ROSE. ​

• Small and rural facilities are unable to perform ROSE due to lack of manpower resources.

There is currently a growing trend in the ordering of molecular markers on FNA specimens.

• ROSE has evolved to help maximize the material recovered from FNA for molecular

   analysis, adding further to the ROSE demand .
