The QCA device is intended to detect and classify cells of clinical interest based on

recognition of cellular areas of particular color and chromatic intensity. In this software

application, the QCA device is intended to measure and quantitate the percentage and

intensity of positively stained nuclei in formalin-fixed, paraffin-embedded tissue specimens

immunohistochemically stained for estrogen receptors.

It is indicated for use as an aid in the management, prognosis and prediction of therapy

outcomes of breast cancer when used with reagents validated for those indications.

The QCA system is an adjunctive computer-assisted methodology to assist the reproducibility

of a qualified pathologist in the acquisition and measurement of images from microscopic

slides of breast cancer specimens stained for the presence of estrogen (ER) nuclear receptor

protein. The accuracy of the test result depends upon the quality of immunohistochemical

staining. It is the responsibility of a qualified pathologist to employ appropriate morphological

studies and controls to assure the validity of the QCA ER scores.

Indications for use as stated in the FDA summary.
