S100A12 and bacterial urinary tract infection: Compared to treatment-naïve TCC/PCA dogs, urinary S100A12 concentrations were also lower in TCC/PCA dogs undergoing treatment, but the difference was only significant for S100A12Cre (P = 0.0416; P = 0.0664 for S100A12USG), whereas dogs with a UTI had numerically higher (but not significant) S100A12USG and S100A12Cre (both P = 1.0000).
