Intraoperative tests (RD‑100i OSNA system and Metasin test) for detecting sentinel lymph node metastases in breast cancer

The RD‑100i OSNA system (Sysmex UK) and the Metasin test (TIB MOLBIOL) are intraoperative molecular tests that are designed to indicate if cancer has spread to the lymph nodes in people diagnosed with invasive breast cancer.

The Metasin test was developed within the NHS at the Princess Alexandra Hospital in Harlow, Essex. It was CE marked by TIB MOLBIOL in December 2012.
