Figure 4: Results of applying the software analysis on whole slide images of HbH blood smears obtained at ×40 objective on the Hamamatsu NanoZoomer S60™ slide scanner. (a) Screenshot of the Qritive Pantheon™ user interface depicting the results of software analysis. The red dots on the whole slide image are the software identifications of HbH-positive cells detected above a prediction confidence threshold of 0.2. The right-hand column shows the list of identifications. (b) A higher magnification view of the same slide showing details of a confirmed HbH positive identification (red box). In this case, the identified cell had a prediction confidence score of 0.999. (c) False-positive identification of artifacts (black boxes) occurring particularly at the edges of the slide and likely representing stain precipitates. (d) False-positive identification of reticulocytes (light green box) occurred sporadically throughout the slide. HbH: Hemoglobin H
