PLS-DAscores plots for dog breed data collected for three sample types applying the HILIC positive ion mode assay. The sample classes were Norfolk terrier: yellow, Labrador retriever: turquoise, Beagle: dark blue, and Petit Basset Griffon Vendeen: purple. The two blinded DBS samples, blind sample 1: orange and blind sample 2: green, were overlaid on the relevant DBS plots. The 95% confidence ellipses were plotted for each breed class. Components 1 and 2 variances were 34 and 12% (DBS 20 μL), 33 and 13% (DBS 40 μL), and 32 and 10% (plasma).
