## Indications for use
The Bayer Immuno 1™ Her-2/neu Assay is an in vitro, diagnostic device intended for use in the quantitative determination of HER-2/neu in human serum. HER-2/neu values obtained may be used in the follow-up and monitoring of patients with metastatic breast cancer. HER-2/neu values should be used in conjunction with information available from clinical and other diagnostic procedures in the management of breast cancer. The clinical utility of the serum measurement of HER-2/neu as a prognostic indicator for early recurrence and in the management of patients on immunotherapy regimens has not been fully established.
