Chapter 1: Intended Use and Indications for Use
This chapter shows comparison and reproducibility studies for the ER marker.
Intended Use and Indications for Use
The Virtuoso system provides automated digital slide creation, management, analysis, and viewing. It is intended for in vitro
diagnostic use as an aid to the pathologist in the display, detection, counting, review and classification of tissues and cells of clinical
interest based on particular morphology, color, intensity, size, pattern and shape.
The IHC ER (SP1) Digital Read and Image Analysis applications are intended for use as an aid to the pathologist in the detection
and quantitative measurement of estrogen receptor (ER) protein in formalin-fixed, paraffin-embedded normal and neoplastic tissue.
ER results are indicated for use as an aid in the management, prognosis and prediction of therapy outcomes in breast cancer. When
used with Ventana Medical Systems, Inc. CONFIRM anti-Estrogen Receptor (ER) (SP1) Rabbit Monoclonal Primary Antibody, it
is indicated for use as an aid in the assessment of breast cancer patients for whom endocrine treatment is being considered (but is
not the sole basis for treatment).
Note: The IHC ER (SP1) Digital Read and Image Analysis applications are adjunctive computer-assisted methodologies for the
qualified pathologist in the acquisition and measurement of images from microscope glass slides of breast cancer specimens
stained for the presence of estrogen receptor protein. The pathologist should verify agreement with the Image Analysis
software application score. The accuracy of the test results depends on the quality of the immunohistochemical staining. It is
the responsibility of a qualified pathologist to employ appropriate morphological studies and controls as specified in the
instructions for the CONFIRM anti-Estrogen Receptor (ER) (SP1) Rabbit Monoclonal Primary Antibody assay used to assure the
validity of the iScan System for IHC ER Digital Read and Image Analysis scores. The actual correlation of CONFIRM anti-Estrogen
Receptor (ER) (SP1) Rabbit Monoclonal Primary Antibody to clinical outcome has not been established.
Summary and Explanation
The Virtuoso system for ER SP1 is an instrument and software system designed to assist the qualified pathologist in the consistent
quantitative assessment of protein expression in immunohistochemically (IHC) stained histologic sections from formalin-fixed,
paraffin-embedded (FFPE) normal and neoplastic tissues. The Virtuoso system can be used for review of digitized images of
histologic sections with image analysis algorithms (Companion Algorithm Virtuoso image analysis applications), or without
Companion Algorithm image analysis algorithms (Virtuoso Digital Read applications).
Digital Read applications present images on the computer screen in the same manner as one would see with a manual microscope,
inclusive of the pathologist's ability to select any areas of interest and the option of various magnification levels. For the Companion
Algorithm image analysis applications, the pathologist may use the system software to select and outline one or several field of views,
(FOVs), and each FOV may be viewed at various magnifications and then analyzed by the software (analysis at 20x magnification);
a count of the total number of target cells and the number interpreted by the algorithm as positive and negative is generated. The
pathologist can accept the score provided by the algorithm, or may override the score with a different score. The system requires
competent human intervention at all steps in the analysis process, and the software makes no independent interpretations of the data.
The Virtuoso system consists of a slide scanner, computer, monitor, keyboard, mouse, Companion Algorithm image analysis
algorithms, and software with a user interface. Virtuoso is an end-to-end digital pathology software solution that allows pathology
laboratories to acquire, manage, view, analyze, share, and report on digital images of pathology specimens. Using the Virtuoso
software, the pathologist can view digital images at various magnifications (as previously stated), add annotations, make tissue section
measurements, perform image analysis, and generate reports.
For in vitro diagnostic (IVD) use.
