The present disclosure includes methods of assessing a histologically stained specimen based on a determined color signature of a region of interest of the specimen. Such assessments may be performed for a variety of purposes including but not limited to assessing the quality of the histological stain, as part of identifying one or more biologically relevant features of the image, as part of differentiating one feature of the image from other features of the image, identifying an anomalous area of the stained specimen, classifying cells of the specimen, etc. Also provided are systems configured for performing the disclosed methods and computer readable medium storing instructions for performing steps of the disclosed methods.

Methods and systems for assessing histological stains

Systems and methods for analyzing blood samples, and more specifically for performing a nucleated red blood cell (nRBC) analysis. The systems and methods screen a blood sample by means of fluorescence staining and a fluorescence triggering strategy, to identify nuclei-containing particles within the blood sample. As such, interference from unlysed red blood cells (RBCs) and fragments of lysed RBCs is substantially eliminated. The systems and methods also enable development of relatively milder reagent(s), suitable for assays of samples containing fragile white blood cells (WBCs). In one embodiment, the systems and methods include: (a) staining a blood sample with an exclusive cell membrane permeable fluorescent dye; (b) using a fluorescence trigger to screen the blood sample for nuclei-containing particles; and (c) using measurements of light scatter and fluorescence emission to distinguish nRBCs from WBCs.
