“…All this envisages the devising and validating of various on‐field, pen‐side point‐of‐care tests (POCT), charts, and palettes, which may be cheaper, quicker, and reliable for estimation of physiological attributes which may provide a prognostic/diagnostic approach to the animal's health. In human medical sciences, many such color charts have been validated and are being used profusely such as reference charts for serum chemistry parameters (Bakar et al, 2017; Ni et al, 2021), mobile‐based color indicators (Archibong et al, 2017), Centers for Disease Control and Prevention (CDC)‐devised reference hemolysis palette (Control & Prevention, 2019), and bilirubin color cards (Singh et al, 2022). However, to the best of knowledge, no such charts/color palettes are in vogue for veterinary practice except FAMACHA© chart for detecting anemia through color matching of the mucus membranes of the sheep eyes (Grace et al, 2007; Moors & Gauly, 2009).…”
