No
The document describes image analysis capabilities but does not explicitly mention the use of AI, ML, or related terms like deep learning or neural networks. The analysis is based on "color, intensity, size, pattern and shape," which can be achieved with traditional image processing algorithms.
No
The device is described as an aid to the pathologist for diagnosis (display, detection, counting, and classification of tissues and cells; semi-quantitative measurement of HER2/neu) and assessment for treatment consideration, not for treating a condition itself. Therefore, it is a diagnostic device, not a therapeutic one.
Yes
The device "is intended for in vitro diagnostic use as an aid to the pathologist in the display, detection, counting and classification of tissues and cells of clinical interest" and includes an "IHC HER2 Image Analysis application is intended for use as an aid to the pathologist in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2)". These statements clearly indicate its use in providing information for diagnosis.
No
The device description explicitly states that the system components include an automated digital microscope slide scanner, computer, color monitor, keyboard, and digital pathology information management software. This indicates the device is a system with both hardware and software components, not software-only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use Statement: The "Intended Use / Indications for Use" section explicitly states: "It is intended for in vitro diagnostic use as an aid to the pathologist..." This is a clear declaration of its intended purpose as an IVD.
- Accessory to an IVD: The IHC HER2 Image Analysis application is described as an "accessory to the Dako HercepTest™," which is a known IVD used for HER2 testing. This further reinforces its role within the in vitro diagnostic process.
- Clinical Decision Making: The device is intended to aid pathologists in the "display, detection, counting and classification of tissues and cells of clinical interest" and specifically in the "semi-quantitative measurement of HER2/neu" to aid in the assessment of breast cancer patients for whom HERCEPTIN® treatment is being considered. This directly relates to providing information for clinical decision-making based on in vitro analysis of biological specimens.
- Analysis of Biological Specimens: The system analyzes digital images derived from "formalin-fixed, paraffin-embedded normal and neoplastic tissue," which are biological specimens.
All these points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or treatment.

Intended Use / Indications for Use
The ScanScope System is an automated digital slide creation, management, viewing and analysis system. It is intended for in vitro diagnostic use as an aid to the pathologist in the display, detection, counting and classification of tissues and cells of clinical interest based on particular color, intensity, size, pattern and shape.
The IHC HER2 Image Analysis application is intended for use as an aid to the pathologist in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2) in formalin-fixed, paraffin-embedded normal and neoplastic tissue.
The IHC HER2 Image Analysis application is intended for use as an accessory to the Dako HercepTest™ to aid in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2) in formalin-fixed, paraffin-embedded normal and neoplastic tissue. When used with the Dako HercepTest™, it is indicated for use as an aid in the assessment of breast cancer patients for whom HERCEPTIN® (Trastuzumab) treatment is being considered. Note: The IHC HER2 Image Analysis application is an adjunctive computer-assisted methodology to assist the reproducibility of a qualified pathologist in the acquisition and measurement of images from microscope slides of breast cancer specimens stained for the presence of HER-2 receptor protein. The accuracy of the test result depends upon 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 Dako HercepTest™ to assure the validity of the IHC HER2 Image Analysis application assisted HER-2/neu score. The actual correlation of the Dako HercepTest™ to Herceptin® clinical outcome has not been established.

A multi-site study was conducted at two clinical sites to compare the performance of Aperio's IHC HER2 Image Analysis to manual microscopy. 180 formalin-fixed, paraffinembedded breast tissue specimens immunohistochemically stained using Dako's HerceptTest™ were used for this study; 80 specimens with approximately equal HER2 score distribution from site 1, and 100 routine specimens from site 2. At each site, three pathologists performed a blinded read of the glass slides using a microscope and reported the HER2 score for each of the slides. The glass slides were scanned at Aperio using a different ScanScope for each site, and after a wash-out period of over one week and randomization of the slides, the same three pathologists remotely viewed and outlined a representative set of tumor regions to be analyzed by the IHC HER2 image analysis. The pathologists received feedback on the way they outlined tumor regions for their first 3 to 7 slides before the slides were analyzed. The algorithm itself was run in batch mode blinded from the pathologists to avoid any influence of the pathologists in their choice of the tumor regions. The algorithm was used "out of the box". The algorithm reported the HER2 score for each of the three pathologists for each of the slides.

§ 864.1860 Immunohistochemistry reagents and kits.
(a)
Identification. Immunohistochemistry test systems (IHC's) are in vitro diagnostic devices consisting of polyclonal or monoclonal antibodies labeled with directions for use and performance claims, which may be packaged with ancillary reagents in kits. Their intended use is to identify, by immunological techniques, antigens in tissues or cytologic specimens. Similar devices intended for use with flow cytometry devices are not considered IHC's.(b)
Classification of immunohistochemistry devices. (1) Class I (general controls). Except as described in paragraphs (b)(2) and (b)(3) of this section, these devices are exempt from the premarket notification requirements in part 807, subpart E of this chapter. This exemption applies to IHC's that provide the pathologist with adjunctive diagnostic information that may be incorporated into the pathologist's report, but that is not ordinarily reported to the clinician as an independent finding. These IHC's are used after the primary diagnosis of tumor (neoplasm) has been made by conventional histopathology using nonimmunologic histochemical stains, such as hematoxylin and eosin. Examples of class I IHC's are differentiation markers that are used as adjunctive tests to subclassify tumors, such as keratin.(2) Class II (special control, guidance document: “FDA Guidance for Submission of Immunohistochemistry Applications to the FDA,” Center for Devices and Radiologic Health, 1998). These IHC's are intended for the detection and/or measurement of certain target analytes in order to provide prognostic or predictive data that are not directly confirmed by routine histopathologic internal and external control specimens. These IHC's provide the pathologist with information that is ordinarily reported as independent diagnostic information to the ordering clinician, and the claims associated with these data are widely accepted and supported by valid scientific evidence. Examples of class II IHC's are those intended for semiquantitative measurement of an analyte, such as hormone receptors in breast cancer.
(3) Class III (premarket approval). IHC's intended for any use not described in paragraphs (b)(1) or (b)(2) of this section.
(c)
Date of PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the Federal Food, Drug, and Cosmetic Act is required for any device described in paragraph (b)(3) of this section before this device may be commercially distributed. See § 864.3.

Overview of System Operation: The laboratory technician or operator loads glass microscope slides into a specially designed slide carrier with a capacity of up to 120 slides. The scanning process begins when the operator starts the ScanScope scanner and finishes when the scanner has completed scanning of all loaded slides. As each glass slide is processed, the system automatically stores individual "striped" images of the tissue contained on the glass slide and integrates the striped images into a single digital slide image, which represents a histological reconstruction of the entire tissue section. After scanning is completed, the operator is able to view and perform certain analytical tests on the digital slides.
21 CFR 807.92(a)(5): Intended use and labeled indications for use:
The ScanScope System is an automated digital slide creation, management, viewing and analysissystem. It is intended for in vitro diagnostic use as an aid to the pathologist in the display, detection, counting and classification of tissues and cells of clinical interest based on particular color, intensity, size, pattern and shape.
The IHC HER2 Image Analysis application is intended for use as an aid to the pathologist in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2) in formalin-fixed, paraffin-embedded normal and neoplastic tissue.

Indications for Use
510(k) Number (if known): _ K07 | | 28
Device Name: ScanScope® XT System
Indications for Use:
The ScanScope System is an automated digital slide creation, management, viewing and analysis system. It is intended for in vitro diagnostic use as an aid to the pathologist in the display, detection, counting and classification of tissues and cells of clinical interest based on particular color, intensity, size, pattern and shape.
The IHC HER2 Image Analysis application is intended for use as an aid to the pathologist in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2) in formalin-fixed, paraffin-embedded normal and neoplastic tissue.
The IHC HER2 Image Analysis application is intended for use as an accessory to the Dako HercepTest™ to aid in the detection and semi-quantitative measurement of HER2/neu (c-erbB-2) in formalin-fixed, paraffin-embedded normal and neoplastic tissue. When used with the Dako HercepTest™, it is indicated for use as an aid in the assessment of breast cancer patients for whom HERCEPTIN® (Trastuzumab) treatment is being considered. Note: The IHC HER2 Image Analysis application is an adjunctive computer-assisted methodology to assist the reproducibility of a qualified pathologist in the acquisition and measurement of images from microscope slides of breast cancer specimens stained for the presence of HER-2 receptor protein. The accuracy of the test result depends upon 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 Dako HercepTest™ to assure the validity of the IHC HER2 Image Analysis application assisted HER-2/neu score. The actual correlation of the Dako HercepTest™ to Herceptin® clinical outcome has not been established.
